Very Professional and Super Friendly

Dr. Cantwell was very professional and super friendly. His office staff was very polite and helped me set up an appointment very quickly. I had a vasectomy done by Dr. Cantwell and it was very quick and painless. I highly recommend using him and his staff and will let all my friends family know about him.

Professional, Approachable, and Thorough

The nurse was very efficient and pleasant. Dr Merrell was very professional, approachable, and thorough. Visiting a urologist for my first time did concern me. Dr Merrell answered all my questions, provided complete information about my situation and made me feel confident with the follow-on steps. I will recommend him.

Make You Feel So Comfortable

Dr Dineen is a very over qualified urologist. You don’t need to leave town to find a good urologist there’s one right here in Daytona Beach. I am a 43-year-old female and there’s nothing more embarrassing than having to go to your first urology visit at such a young age but they make you feel so comfortable I can’t say enough good things about Dr Dineen and his staff.
