I’ve been at USQ Derm for 5 years with Dr. Claire Chang. She’s honest, warm and the best at her craft. Never pushes more services and explains everything I’m interested in articulately. Her staff is lovely, too. Highly recommend.

Dr Black and Dr Chang are both wonderful Dermatologists and experts in their fields and are both highly effective in using the latest modalities in aesthetics. Have been looking younger and younger since I have been coming here :-)
