    Care provider is always prompt in entering examination room at conclusion of nurses work. Always listens carefully to concerns and issues, reviews the results of testing or procedures, and responds with easy to understand guidance, and arranges follow up visits and blood work for annual physical. Always courteous and friendly.

    If we didn't discuss my medications, it was because I have been taking them for several years. This visit was a follow-up to a visit to the Emergency Room.

    Dr. DeCastro spent more time with me and helped me with my rash in a way my dermatologist (2 weeks ago) did not. Very much appreciated!
