Patient Testimonials

Your Trust, Our Greatest Achievement

5 stars are not enough. I could not be more pleased. After living 15 years with a bad augmentation, the breast revision that Dr Dang performed exceeded my expectations. His bedside manner was awesome and he was both responsive and attentive from consultation through the final 6week follow up. I would recommend him without reservation.

I’ve been a patient of Dr. Davis and Dr. Mussman for years. They’re very professional, caring, and provide the best care that you’ll ever receive in the Valley. I highly recommend them for your skin care!

- Steven M.

My first time consulting with Jada! She was INCREDIBLE, guiding me every step of the way with common sense methods to make me look & feel my best, as well as educating me thoroughly throughout the process & procedure. She is AMAZING & I will always return to her & Regency for any help I need cosmetically. Also, Dr. Mussman is a surgical genius, & helped me become my best self ever with the neck procedure. At 73 years old it is very rare to find health care providers that can be trusted so completely. Thank you, Jada & Dr. Mussman!
