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!
