This place is the greatest!!! I have had several colonoscopies in my lifetime, at various places, and this place plus the whole experience was a vacation compared to my other experiences! I know that might sound outlandish to some but my husband just had his turn and he could not believe how easy it was and how great he felt afterwards. The workers and the doctors were so nice and made both of us feel very comfortable, for both of our visits. Both of us, had nurse Jennifer and she is so nice and caring! When you wake up from the anesthesia, you can’t believe how easy it is to wake up and how good you feel. The facility is also very clean and they are all very thorough with everything. I highly recommend this place!


Having a procedure is always nerve racking but the staff was fantastic. Answered all my questions and helped me through the entire process. During my procedure the nurse anesthetist was also fantastic. She explained everything and I honestly did not feel a thing . The doctor was amazing, he calmed my nerves , and made me feel like I could trust him . He was simply put completely professional and very empathetic. I will only go to the Gastro Group for all my care !!

Dr Ann Lee was great. Nicole at the front desk was good too. My husband had his appendix removed 2 weeks ago. On 9/5/2017 he had his follow up appointment to remove his staples I felt like the doctor wanted to get rid of us. So today I search online and found the Gastro group through another site. I called in an Nicole helped me she even check the cancellation an was able to get me in for a same day appointment. We walked in and the waiting room was packed. Our appointment was at 4pm we got into the room at 4:19pm. Dr Ann Lee came in shortly after she was great. She listened, was attentive to our concerns, she asked relevant questions then she decided to get Michael some test. Will update once we get to the next steps

I had a Colonoscopy in May 2020. All the office staff were nice. My doctor and nurses made sure I was at ease about my procedure because I was very nervous. My folks referred me to the Gastro Group. I would recommend them to My friends & other family members. They also called to check on Me to make sure I was feeling okay. Thank you Gastro Group!
