PATIENT REVIEWS
Dr. Do is trustworthy, very thorough, and knowledgeable. I would not hesitate to have Dr. Do perform another Colonoscopy exam. I highly recommend Dr. DO.
I only spoke with Dr Jantz briefly before the procedure and I felt very confident that I was in the best of care. She is very skilled and this not being my first rodeo, I felt safe and assured with the years of experience in her gifted hands.
However, after my procedure, I received a text to comply if I was have any issues with YES or NO the day after. I replied with a YES and no one reached out to me. I had a splitting headache and my left gland under my ear had developed a painful knot. My throat felt raw and the night after the procedure I regurgitated through my mouth and nose, leaving a burning sensation from acid reflux. I live alone so I got a little panicked that no one reached out to me. I called Dr Jantz number and was referred to an assortment of buttons to push. I finally reached a kind male medical nurse to assure me this was normal and scheduled a follow up visit in two months.

The staff and Dr Kethu were very nice and helpful. The endoscopy went smooth and easy with a good outcome and explanation of my diagnosis.
Doctor Son T. Do is extremely knowledgeable and patient.
She takes plenty of time with me and answers all my questions.
I will definitely follow up. Thank you so much.💕🙏🏾
Dr. Dhavaleshwar seems knowledgeable and, caring and answered all my questions and concerns.
The only reason for not giving five stars is the medical assistant who came in and asked about my history, medications etc. She was a bit rude and displayed some contempt when I wasn’t able to answer all her questions. Despite her behavior, I would. Still return to see Dr. Dhavaleshwar.
Chandra
I always feel welcome and cared for my needs when I go for my visits! I truly appreciate him!
His recommendations have helped me manage my medical condition in a better manner. His staff is very helpful, professional and swift. I recommend Dr. Chandra without any hesitation and wish him good luck in all his endeavors.
