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.

Dr Merriman is a great doctor who listens and cares about his patients.

Expert care
As a long term patient with a chronic liver condition I’ve been seeing Dr Merriman for several years. He always takes the time necessary to explain what’s going on. He’s a wealth of knowledge far and above any that I’ve seen in the past.

Outstanding physician
I had the pleasure of being under Dr. Merriman’s care for over a year. I’m grateful to have had him as my liver specialist. He consistently took time to listen and answer my questions. Dr. Merriman is thorough, kind, and has excellent bedside manner. His staff were also pleasant and helpful. My primary care provider highly recommended Dr. Merriman, and I agree— he is outstanding. Thank you, Dr. Merriman.

Dr. Merriman is amazing. He's a great listener, explains everything thoroughly, and in terms my husband and I can understand. He also encourages questions and dialogue. I never feel rushed when we are with him, he values the time. He's also sharp and one of the leaders in his field worldwide. I have literally put my life in his hands and know that he has the experience and intelligence to treat the best way possible with what's available today.

I was referred to Dr Merriman after being diagnosed with liver disease due to Alfpha 1 Antitrypsin Deficiency in Montana. I just had my initial evaluation yesterday. My cousin, who is a physician in the area, and my son who flew in from NYC, accompanied me to the appointment. I wondered if my showing up with a team would be a problem but we were all welcomed with open arms! Excellent information, excellent interaction, couldn't be more pleased. Looking forward to continuing in his care!
