"Dr. Montague has the ability to ask the right questions and listens intently to get to the fix. Every time I have seen her was a great experience."

"Dr. Colton is probably the best doctor I have ever had. She listened intently, zeroed in on my condition immediately with complete understanding of the necessary steps for tests going forward, and explained things so clearly. I felt completely safe and confident in her care and ability to address my problem. Staff were excellent also."
