Had a fantastic experience at UnionDerm. The facilities, front and back staff (Abbie and Kathryn) were exceptional. Dr. Humphrey is an amazing physician - extremely knowledgeable with a great bedside manner. My treatment was personalized and effective! Cannot recommend more highly!

Had a really great experience with Dr. Claire Chang at UnionDerm. As a guy new to cosmetic treatments, I was a bit hesitant, but she made the whole process feel comfortable and low-pressure. She took the time to understand what I wanted and gave honest, thoughtful recommendations.
