The PA, Ally DeRosa, is fantastic! I highly recommend this dermatologist. She is very knowledgeable, professional, caring, takes time to answer all of your questions, and she has great follow through in calling you personally withShow more lab results. Once when a cyst was possibly infected she called in Dr. Robles to confirm her diagnosis. He told us that she was correct and to proceed with drainingthe cyst & prescribing antibiotics. The dr. checked on the procedure and was pleased with the outcome.
