Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Unparalleled
Simply put. Dr. Marion in my estimation is unparalleled as a gastroenterologist and as a compassionate, systemic thinking healthcare provider who is able to address the body,mind and spirit of the patient. He is also most importantly a HOPE MERCHANT. I would not be alive without his expert care.

Excellent Doctor
Both my husband and I use him. He is very knowledgeable, courteous, friendly. Was particularly warm with me when I expressed concerns about my husband. He listens and answers questions. Certainly seems as though he really cares about his patients -- and their families.

BEST CHRONS DOCTOR AROUND
I went 4-5 years with various doctors putting me on multiple medications that never worked. As soon as I saw Dr. Marion, I got the help I needed immediately. My quality of life went from a 3/10 to a 10/10. He is always thorough, timely and responsive. I would never choose a different doctor.

Great doctor!
I've been under his care for almost 15 years after my Crohn's surgery. I had no quality of life pre-surgery and Dr. Marion has kept my Crohn's under control ever since. He is extremely patient, knowledgeable and will stay with me in the room until I have all my questions answered. I highly recommend him!

Dr. Marion is a truly amazing doctor and person. He truly cares about his patients beyond what is required. I'm a medical provider and I know what is the normal level of care and he far exceeds it. He saved my life. He also was a true inspiration for me to be the provider I have become to be.

Stay away from this doctor!! He treated my daughter for Crohn’s disease. Initially the humira he put her on put her in remission for a little more than two years. She started to have flare ups because it quit working. Was in and out of the hospital. All he did was keep putting her on high doses of prednisone instead of changing her medication, he kept masking the problem. Every time she would start to wean off and was nearly done with it she would start to flare again. He is over booked with patients and she couldn’t get in to see him only could correspond through email. During all this he placed her on another medication to help her with the pain she was experiencing. She finally sought a new provider.Her new doctor said at their first visit after reading over her ungodly thick medical records that she was changing her medication because it was no longer working. She is now having manic episodes due to the steroid use that she is carefully being weaned her off from It’s been horrible

This guy is literally a monster. I can think of no better adjective. He is incredibly aggressive and has an absurdly inflated ego. Should you ask him a question that he feels questions his decision making, he will go for your jugular and attempt to make you feel small. He’s a bully and a heartless, frustrated man. Please find yourself a better professional.

Without a doubt, THE BEST doctor you can have. I've been struggling with Crohn's disease with little success from the treatment prescribed prior to seeing Dr. Marion. Dr. Marion took the time to listen to my situation and developed a plan to quickly address my condition. His bedside manner is unlike any doctor you will find today. I'm now on the road to recovery thanks to Dr. Marion and a very grateful to have found him. I also want to recognize his nurse Andrina. She is outstanding!!

Dr. Marion is the best! I have been his patient for 10 years and he is the only dr that could put my UC in remission. He has an excellent bedside manor and truly takes the time with his patients. Worth the drive if he is a distance.
