Dr. Thomas Charles Knopp, DO

Dr. Knopp is an exceptional gastroenterologist. He listens carefully to all my concerns, explains my conditions in depth and has solutions to my problems. The office staff is very professional and welcoming. I highly recommend this establishment!

I had a wonderful experience with Dr. Knopp today, 8/10/2026 and I honestly cannot say enough good things about him and his staff. He is so much more than someone who simply has a medical degree. He is a doctor who truly listens when you speak, hears your concerns, and makes you feel like your health genuinely matters to him. From the moment I made my first phone call to his office until the moment I walked out the door, I was treated with kindness, compassion, and respect. Everyone I encountered was friendly, personable, and genuinely caring. I could tell that patient care wasn’t just something they were doing—it truly seemed to matter to them. Dr. Knopp took the time to listen to everything I had to say and never once made me feel rushed or like I was just another patient on a schedule. He asked questions, explained things in a way I could understand, and took my concerns seriously. Most importantly, I felt like he genuinely cared about finding answers and helping me feel… better. What stood out to me the most was his compassion. When you are worried, hurting, or unsure about what is happening with your health, having a doctor who treats you with patience, kindness, and understanding means more than words can express. There is such a sense of comfort in knowing you have a doctor who is willing to listen, investigate, and go the extra mile for you. I walked out of the office feeling heard, respected, and reassured. That says so much about the kind of doctor Dr. Knopp is and the kind of team he has surrounding him. Thank you, Dr. Knopp, and thank you to your entire staff for making what can sometimes be an uncomfortable or stressful experience feel so much easier. Your kindness and compassion did not go unnoticed. I am truly grateful for the care I received today and feel blessed to have found a doctor who genuinely cares about his patients.

Terrible, arrogant doctor!!! Did not even offer to treat!

Awesome dr he really care about his patients

I love him and his staff been going to him for 5 years very professional and great bedside manners he really cares about his patients.

Dr. Knopp is knowledgable, understanding and straightforward. My prognosis was grim the first time I saw him and 2 years was the max. But thanks to Dr. Knopp and CSGA I'm here almost 5 years later. I recommend him to everyone.

he listened with care and took his time it seemed like I was the only patient for the day. Then he quickly ordered tests to get a quick diagnosis so my six year problem is now resolved.

Dr did not seem to listen. Nice staff but dr prescribed medication I did not need or want as opposed to alleviating pain. In notes listed he suggested lifestyle modification which I never needed. I don’t drink soda, or alcohol or smoke. All modifications he suggested. Also I had already given up tomatoe based products. Pain was intermittent not constant. Meds were debilitating not helpful.

Dr Knopp is a genuinely kind and caring physician. His staff are friendly and helpful as well. They are the best!

I found Dr. Knopp to be a caring and knowledgeable physician. He is very easy to talk to, listens carefully, and explains the issues and choices clearly and succinctly. I experienced a high level of trust in his judgment and approach. I would recommend him to anyone seeking a gastroenterologist.
