I’ve been seeing Dr. Robles for 2 year, but this time I saw Alexandra and she was amazing as well! I had a terrible eczema flare postpartum and explained that I’m currently breastfeeding. She made sure to research what treatment wShow moreould work best to control my flare while still being able to carefully breastfeed my baby. She listened to all concerns that I had and as very detailed about treatment. She’s given me relief while trying to figure out the next step. Highly recommend!

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.
