About NVDC

North Valley Dermatology Center was established by Dr. Donald F. Richey and Dr. Stephen Schwartz after over 25 years of private practice. O. Jay On trained under Dr. Schwartz and took over his practice after Dr. Schwartz retired. Since then, Dr. Vannucci and Dr. Sajben joined Dr. Richey’s practice and have since started their own dermatology practices. In 2010, North Valley Dermatology Center became a partnership between Dr. Richey, Dr. Vannucci and Dr. Sajben.

Dr. Hodari, Jacqueline Hollcraft and Renee Christenson now complete the team at North Valley Dermatology Center.
