Dr. Collin is Friendly with excellent bed side manners. He takes his time with his patients, and is never in a rush – he right away came up with diagnosis and treatment plan. when I left there I felt all my questions were answered. His staff is friendly and attentive. The IV suite with Dawn kept me out of the hospital ! Her reassurance and care made going through this ordeal a breeze instead of the ordeal I anticipated. recommend this office anytime.

He fought to get my insurance to cover the treatment I needed and advocated for me to help speed up my care with other specialists. He is a known charitable doctor with his own not-for-profit clinic he runs to help those living with infectious diseases.

They should all be like this guy. There are people who should be in this profession and others perhaps not. Dr. Collin imparts to both patient and family a sense of trust and sincerity for which I am very grateful.
