Dr. Simas is an amazing, caring intelligent man. Him and his staff are wonderful and very caring. I would like to say thank you to Miss Maddie, Jackie, Lilly and Dr. Simas. Without your help who knows where I would be right now. I have been seeing Dr. Simas for almost 2 years now and paid self pay due to not having the correct insurance. I could easily go to a provider that takes my insurance but why would I do that. Dr. Simas is worth more then words can describe.

Unprofessional and unwilling to consider patient needs. Poor communication concerning billing and nonexistent follow up. This practice apparently exists simply to push suboxone on desperate patients without regard.

Dr.Simas and his staff are so amazing and caring. They have always been there for me whenever I have needed anything and they do both my Suboxone treatment and my mental health treatment. They prescribe for both. The staff really cares and makes me feel like I am an individual not just a number like most offices. When I am going through a hard time they even call and check on me to see how I am doing. I have been clean for 2 years with their help. I am a miracle because of this office.
