The staff is always so friendly and compassionate and the Dr’s are great
Really bad experience today. Doctor took 30 minutes to get me in. Used to enjoy my visits here not sure what’s changed.
Dr Gamsey and his staff are always very professional and competent. I am very happy with this group.
Dr. Domanski was kind, very knowledgeable, helpful, and fast! He also advised me in other areas of my health.
Was a straight forward procedure. They got me in and out very quickly just how I like it.
Happy with experience doctor was professional and gave information about the procedure and the findings, waiting room was overcrowded but with could restrictions understandably
Very positive and kind and considerate group makes you feel calm and comfortable
Information was good and informative
I would encourage others to come to this office
Very kind and easy to talk to. Willing to take on a patient with unusual symptoms.
Their web site makes NO mention that, if a patient meets the requirements, it’s NOT necessary to have an in-person office consult before getting a colonoscopy. The appointment receptionist doesn’t mention that possibility either (even when …
I truly appreciate the kind and professional care received from Dr. Tiongco.
The procedure went along smoothly and on time.
Over the many years I’ve had about five and this was one of the best. No issues.
EVERYTHING WAS GREAT!! This was the first time Ive seen Dr Sullivan and je is definitely the best Gastro Dr I’ve been to!!
Friendly and polite staff Took every detail of history, experienced and good listener Dr spend max time as needed, thorough check up , very satisfying visit
Everyone was extremely warm and polite. Health conscious too. Kept masks on and wiped down everything that patients used.
I have been going to Dr Tiongco for about 20 years
And I wouldn’t go to anyone else .
Dr Tiongco has always explained everything in terms that I can understand and gives me all the time I need at an appointment. ❤️
Never get call backs after tests or to set up testing and then when you call they have a hard time pulling reports or finding your order. Then you have to wait again for nurse to see and pass on to Dr. for review. I am not impressed by the administrative staff. I am not sure if I will continue after this test result.
Was given great care by Dr. Makdisi and his staff. He was happy to hear I am feeling a lot better.
I’m not too sure what Jenny is going on about, I’ve had many colonoscopies here, and it is a very straightforward process. To my knowledge, I do not recall ever needing anyone to “verbally” tell me anything about the process. Just read the paper you are given?
Staff is very professional and friendly. All questions answered when asked. Staff introduced themselves by first name and what they were there to do. They put patient at ease.
Great Physician! Very Thorough and detailed oriented! Expertise in GI Field! Courtesy and Kind! Strongly Recommended to All who are in need of a GI Specialist!
Dr. Mendu and her staff were awesome. This was my second visit. Just like an automated carwash. In and out no wait time. 😃 …
There are not enough words to express how awesome everyone here is. From my Dr., nurses and all the staff. They truly care!!!
Dr. Domanski was very patient and showed concern. He listened to my problems. I would recommend him to my family and friends .
First colonoscapy, Dr. And staff made me feel at ease. Very satisfied with entire procedure.
Dr. Domeski is very professional, caring and kind. The office staff is very nice. I would highly recommend Dr. Domeski.
Care to explain how an esophagus can get punctured in a procedure and the “doctor” if you can even call them one doesn’t remedy or work towards a solution ? Maybe Sullivan magically has answers ?
Dr Riveria is awesome and takes his time to understand his patients needs.
The care you receive is just what you would want and expect. The entire staff are so comforting, putting your mind at complete ease.
Very friendly staff doctor was very patient and professional made me very comfortable would recommend to many more people great job
Hi Dr. Mendu, thank you so much for taking good care of me. I’m doing well with no issues at all—happy Holidays to you and your family.
It was a very comfortable experience. I greatly appreciate Dr.Shoba Mendu and her team for their excellent service. Thank you again for your kindness.
I was treated very well by all staff members at Gastroenterology Associates of Tidewater and Dr Steven Dandalides was very thorough in covering any concerns that I had with my situation.
Dr. Rivera, Debbie and the whole staff were friendly and professional. Dr. took time to allay my fears about upcoming colonoscopy, and I’m truly grateful.
I luv luv😍🙏🏾Dr.Shoba Mendu so much. I’ve been with her a couple of years now,and she is really intelligent, respectful at all times that I see her. I’m always pleased with her service. …
My first time getting this test other then the prep solution causing me to barf. It was quick and over and I have no memory of the testing being done. The staff was very nice.
Dr Makdisi is very personal with you and gives quality care as well as great feedback. Services are prompt and well organized.
From the beginning of my appointment at the front desk until the moment my procedure was complete, everyone was attentive, professional, informative and kind. Thank you so much, see you in 5 years!!
Never returned phone call been 3 days
Friendly, professional, efficient. Dr. Sullivan and the whole team really put ma at ease.
Great practice. Great care.
The best choice I made switching my GI doctor to Tioncgo. He has given me comfort that no other GI could. I would definitely recommend him.
very trust worthy specialist. I’ve been in his care for close to decades
i would’nt go to any other gastro doctor. Felix is the best.
Dr Makdisi and his staff were wonderful, they explained the procedure and made you feel at ease. They really take good care of you from check in to checkout.
Worst customer service EVER. Their hours don’t match what they have listed and you won’t be able to reach them before 9 am despite it saying that they open at 8 – you’ll just get an answering machine. They want you to check your labs online …
First time for my colonoscopy. It was a pleasant experience. The staff was super friendly and helpful. I highly recommend them.
Very quick to get an appointment and treatment…Amazing service not sure how to describe the treatment butt smooth and easy thx Doc…
Very professional group. Front office very helpful with scheduling, nurses great about follow up and answering questions and Dr. Makdisi was excellent. Highly recommended.
Dr.Makdisi is a great doctor. I trust him for all of my gastroenterology procedures.
Very well organized. All my questions were answered and the staff, especially at the procedure center, were awesome.
The appointment was seamless, the technicians and nurses were friendly, and Dr. Tiongco was thorough and knowledgeable. I would highly recommend this doctor and practice!
Today was my first visit to this office. Dr. Tiongco is very professional and easy to talk to. His staff, Debbie and Tara, are an asset to his office.
Dr. Domanski is truly a great doctor.. I am a healthcare professional and so I know good care when I see it ,..this whole practice is wonderful. Every person that works there is outstanding.. I wouldn’t go anywhere else
Dr Domanski takes his time and really gets to know his patients AND their problems. Great bedside manner and you can tell he really cares about his patients.
I am very happy with my appointment and provider. Katelyn does a great job explaining everything and is very timely. Thanks for the great care.
Y’all have to get better with the phones. The online portal sometimes has errors taking payment and I’ve been trying to call in for days to make payment. Take my money please 🥺 …
Everyone was so nice. It was a clean, efficient. and caring office. Everyone took care of me and made me very comfirtzble. Dr Mendu did a good job and has a great bedside manner. Great experience!
Very nice and understanding to their patients and will make sure you get the care you needs
Dr.Meade is one of the most caring doctors I have ever met.She takes her time to explain your healthcare needs.Her demeanor is always pleasant.If you ever have a healthcare need for Gastro issue,Dr.Meadu is the go to doctor.
Another fantastic treatment with Dr. Mendu and the staff there.
Professional, caring, prompt. My family and I have multiple procedures and clinical visits over the years, and continue to be grateful and thankful for superb care.
My very first time to have a procedure done, I was very nervous but I gave my trust to Dr Felix Tionko. I had a very good experience from the reception to the procedure room. Dr Tionko was very professional and expert. He is highly recommended. Thank you GAT chesapeake.
Had a good pre procedure meeting which made it clear what I needed to do to get ready. Very professional and courteous.
I am very happy with Gastroenterology Associates and with Dr. Dandalides. The staff are very helpful and are nice. Dr. Dandalides is a caring person who answers your questions and concerns that you may have. Recommend highly for anyone who is looking for gastrointestinal specialist.
The worst experience i have ever had dealing with this office. Staff are not helpful at all and they act as is they are doing you a favor. Not going to go into details but my appointment today was a complete waste of time.
I was having a serious intestinal issue while my original GI Dr gave me an appt in march this situation could not wait an mr René and staff fit me in immediately an I thank them immensely..
Excellent Office and medical service even with the terrible outbreak of COVID 19. Services were provided in a prompt professional atmosphere as usual. I have the highest regards for Dr. Felix Tiongca and his support staff over the years. Due to their diligence, I am alive today.
Dr. Douglas Howerton is excellent. I had an emergency in another city and he took the time on a weekend to call and speak with the doctors to make sure I was receiving appropriate treatment. You can’t ask for a more dedicated doctor.
I was very pleased with the service and interaction of the staff, very friendly, warm and caring. They are very professional and efficient as well as making you feel comfortable in a procedure that makes many uncomfortable. I will use them again without hesitation in the future as an appointment may arise!
Dr Sullivan is really good – very patient and affable. Did my scope and it was a very pleasant experience start to finish. Staff was great too. Highly recommend him.
I always feel cofident leaving, knowing I had the best care. The staff and Dr Domanski are wonderful!
I have receiving at tide water gastroenterology for the last nine years there staff are are courteous and friendly they make you feel welcome from the moment you walk through the door compassionate and caring doctors if you need a colonoscopy the best place to go
Dr. Domanski and the staff were informative, friendly, efficient. This is the second time that I have been treated by Dr. Domanski and I will not go elsewhere to be treated.
I was treated courteously and professionally by all involved in my colonoscopy. Dr. Mendu put me at ease and gave me the good news upon completion. Thank you all. I would recommend you in the future.

I don’t usually leave reviews but I am disappointed with my visit. I waited a good amount of time to be seen by a doctor who was in and out in less than 10 mins, mind you this was also my first visit here. There was no examine given not …
I saw Dr. Sullivan for the first and found that he was concerned about my problem and I fly that I was not rushed thru my appointment. He let me describe my problems and asked questions along the way. I have already recommended him to a friend.
Will never return. Dr. Alan Ramsey was condescending, dismissive, and refused to listen to the things I was trying to convey about my medical history and concerns. As well as leaving me to wait for an additional hour per my scheduled …
Dr.Mendu was nice when I went to my initial appointment. I had to wait about a month and a half to get that appointment.
I was scheduled for a colonoscapy and an endoscopy for the first week of …
Dr. Domanski is a very knowledgeable and most pleasant doctor around. He takes time to explain what’s going on and all options. Very informative and makes you feel like he really cares about your health.
Even though it’s something no one wants to do it was a must for good health and Gastroenterology and their staff made it easy and got me through it. It was painless and the best nap I have had in years. Dr Gamsey was great and had a great …
I’ve been going here for several years now, ever since Dr. Dandalides saved my life by convincing my paranoid former-self, a desperately-ill and equally-petrified woman who was loath to trust anyone in a white coat, to let him try treat my …
Doctor Domanski has been my go-to-guy for issues with my innards. His demeanor and professionalism are comforting in stressful situations. His medical knowledge is encyclopedic. He gets results!
I must say this was my first colonoscopy and if I had to get another one this is where I am going. The check in was swift and the receptionist was Awesome. Dr. Sullivan and his team were great. I was in and out within an hour and didn’t feel a thing.
In the past maybe 8 to 10 years I’ve had a few problems that no doctor could figure out. I have been to several and nobody could figure it out. I went to doctor Makdisi to see if he could help me. I kept complaining about my gallbladder and …
Doctor Sullivan and the staff at Chesapeake General were all very professional, through and addressed all my concerns. My procedure went very well and quickly. I do wish I did not have to wait so long in the waiting room though.
Really poor overall experience. Most of the staff were friendly and welcoming. However, Dr. Gamsey was insensitive and did not give any additional information than I would get online regarding my symptoms. Unfortunately, if you have …
I was very pleased with my experience at Gastroenterology. I recently had a third procedure performed there by Dr. Mendu. Both she and her associates were friendly, putting me at ease and were both efficient and expert in their performance of the duties. I highly recommend this practice.
I had my colonoscopy on Sept 2nd with Dr. Tiongco. Everyone was very nice they took good care of me. Dr Tiongo came and saw me before and after the procedure and put me at ease. I would definitely recommend Dr. Tiongco to my family and friends.
Worst experience ever! My dad had an appt with Dr. Rivera. VERY RUDE! He walked in the room and first thing he said “was why are you here, everything looks fine on your scans”!!! Really????? If everything looked fine they would NOT …
I am truly grateful for the experience that I had on May 18, 2021 in the Chesapeake office. From the time I was taken to the back to get prepped the young man who worked with me the music the anesthesia doctor everything was just awesome. God bless the entire staff.
Dr Domanski was very thorough and had prior to my visit researched and reviewed my records. He explained and answered and was very attentive to my questions and concerns with very understandable explanations. He also provided several …
Review part 2: I do need to add before prepping for a colonoscopy, I noticed Diane neglected to order one of the needed prescriptions I needed Reglan. I contacted her and she blamed the pharmacy. So I had to go without the Reglan while …
Dr Makdesi has been my Dr for over 20 years and I have found him to be extremely knowledgeable, compassionate and understanding. He has brought me through some very hard times and I trust him totally with my care and that of my husband. I cannot convey how highly we think of Dr Makdesi!
The procedure was handled beautifully from check in to check out; there was literally no wait time. The medical personnel were friendly and personable and helped me relax before the procedure. They thoroughly explained what was happening …
Well the staff was very professional and courteous. Knowledgeable and explained things clearly. I would recommend all my friends and family to check them out. Dr. Sullivan and his staff will make you feel very comfortable they will take good care of you. 100% satisfaction.

I have been a patient of Dr. Dandelions for over 10 years. I have always found him to be highly competent and professional. I regret to to learn that he is retiring and will miss his professional care and advice. I wish him well as he …
Enjoy going to the Chesapeake office, the staff are always friendly. The doctor that I see will soon be retiring, to which I was sad to hear. I also see the NP there she’s always a delight to see. I would highly recommend this practice to anyone looking for excellent gastro physicians.
Dr. Rene Rivera and his staff provided great service on both of my visits to his office, he listened to my concerns and gave adequate feedback. While finding good service is rare these days, it’s good to know that there are still businesses that truly care about the standards of services they provide to their patients.
Upon my initial visit, the office was very clean and professional. Everyone adhered to social distancing practices, so I felt comfortable being in the office. Dr. Rivera was very patient and understanding. He has a great bedside manner. So thankful that he was recommended to me.
Dr Dandalides is a great doctor. He really listens to you and comes up with the proper treatment for your condition. I have seen him for many years and I have always been more than satisfied with the outcome. I would recommend him to anyone that needs his help.
Katelynn was very detailed and took time to explain my health concerns. She even went back into my record to try to determine what I was doing wrong with taking certain medications and how I should consume my medication. I just love her bedside manners.
It’s ny first time at a GA. I was very comfortable. My Dr also had great hair. Will leave more after my colonoscapy, which I’m feeling totally ok with.
I was very satisfied with the care I am given. I like that old fashion care of meeting with the doctor in his office. I was recommended to you by my sister. Now we are both sorry to see you retire I know you are ready and family grows up …
The 4 stars are because I had to wait 3 months to see Dr. Mendu as a new patient. Initially, it was 9 weeks and they called in July pushing back 3 weeks to August. GI practices I called, that were in my insurance plan, had waits that …
Dr. Domanski was the most unhurried, attentive, professional doctor I’ve encountered in a very long time, as was his entire staff. We connected by chance and I am so pleased we did. He’s a keeper.
These associates gives excellent care to their patients! They take the time to listen and really shows concern for your health. The staff is very friendly and professional. I highly recommend this Gastronterologist Associates to anyone that is experiencing stomach problems.
Visiting the facility for the first time I was late due to a natural gas leak but they took me anyways and gave me top notch attention and services. The process was not rushed and the staff was courteous and very caring and professional. I would definitely recommend this office to my family and friends. 5 stars
I am very pleased with Dr.Makdisi’s care and giving good instructions for my IBS. I am concerned with the pain I continue to have in my upper left middle. I have thinking about it and I am wondering if I could have my Endoscopy before June …
Dr. Domanski was very nice and thorough. He listen to all my concerns. Showed Empathy on how was feeling. However, the part about my experience, is I didn’t feel like I was being rushed like most doctors do. If you are looking for a doctor that truly cares HE IS YOUR GUY!!!
I was very impressed with doctor Alan Gamsey. He was very knowledgeable and very thorough. I liked his personality and he didn’t rush me through my visit, He listened to everything I had to say. The staff in the office were so courteous, friendly and sweet. I will go back in 6 weeks
Dr. D,
It has been a wonderful experience having had you as our GI for so many years. Much success as you embark on another chapter in your life.
Gastroenterology Associates will be loosing a wonderful doctor.
They are very attentive to their patients needs. Every Doctor I have had the pleasure to meet and be treated by has been very kind and listen to how the patient feels.
I have been seeing Dr. Mendu and her staff for over ten years. They have always been kind, efficient, compassionate, professional and fast. All of these are particularly appreciated when these types of procedures are involved. Thank you, GATI!
Completely disappointed and mostly let down as I care about my health and this place wasted my time.. I made a appointment with them over a month and a half ago and somehow it was canceled and nobody called to let me know. I mean it’s not …
Lately everything I call with a real issue they don’t return a call until almost a week later. Last couple years I’ve had diverticulitis flare ups. I had to run the Patient First for antibiotics before I ended up in ER
I am very happy with the service that I received from Dr. Walid Makdisi and his fabulous team at Gastroenterology Associates of Tidewater, Chesapeake office. From the time that I walked into this establishment up until I was done with my …
I am writing to review your office website rather than your practice. I saw Dr. Domanski for the first-time last week and was impressed. His professionalism and demeanor were nothing short of stellar. Unfortunately, I can’t say the same …
I went to go see Dr. Sullivan. He was so dismissive about what caused me to have certain symptoms when patients are the ones who help doctors diagnose us. The information that we provide them allow them to put it all together and then come …
The wife had blood work done at the family doctor which indicated abnormal liver enzymes. The doctor knew my wife had a gastroenterologist and advised me to make an appointment for as soon as possible. Contacted GATGI and told them about …
Giving 2 stars because all the front desk staff and nurses are amazing, but Dr. Gamsey was not at all worried about me or what was wrong. Rushed through my entire appointment just to tell me something that didn’t make any sense, was …
Everyone was very nice and considerate. The staff was genuinely concerned with my well being. They were also very helpful to each other. The doctor was very professional and thoughtful if his explanation of the experience and the results.

Scheduling my first routine appointment for a colonoscopy with Dr. Brian Sullivan’s office was easy. Rose returned my call promptly to schedule my appointment …
on my recent visit the employees were professional and courtesous. The second floor office was impressive. the first floor waiting room air supply and return are filthy and in need of maintenance. I hope this is remedied prior to my actual visit.
The staff was professional and caring. Dr Mendu was very kind and also professional and caring. I recommend her to all my friends and family.
I was referred here by my PCP, it has been well over 2 weeks, have yet to receive any phone call to talk about making appointments etc. When I called myself all I get is a voicemail that states “ Give us 24/48 hrs & we will return your …
Our experience’s only highlight was the truly wonderful front desk and medical staff we saw during my partner’s procedure at this office. But we felt rushed and dismissed by Dr. Rivera during both consults with him, and he seemed to want to …
