Welcome to Nielsen Dermatology!

Timothy A. Nielsen, M.D. and staff would like to express our sincere appreciation for your continued support. After serving the South Florida community in a group dermatology practice for over 16 years, Dr. Nielsen began his solo private practice in 2013 with a focus on general dermatology, dermatologic surgery, and dermatopathology and a special emphasis on the treatment of skin cancer. We deliver excellent medical care for all your skin care needs.

At Nielsen Dermatology you will be greeted promptly by a friendly doctor and staff where your health care is a priority!

This website is dedicated to the local titans of dermatology: Milton Heard, Vernon Carter, Louis T. Nielsen, James Barrett and Kenneth Folsom, who cared for dermatology patients at the original Dermatology Associates of Boca Raton and Boynton Beach over the last 45 years. I knew every one of these physicians personally and was given a tremendous opportunity to practice with them. Their retirement and/or passing ushered in a new era for me. I am deeply grateful to all of those physicians and look forward to caring for you at Nielsen Dermatology. Our practice helps patients with general dermatology services and treatments, while also being home to skilled dermapathologist who can give biopsies, diagnose and treat skin cancer
