About Our Doctors

William J. Worden, DDS

"Dr. Bill" was born in Chicago, Illinois, but spent the majority of his childhood in a small town outside Vienna, Austria. After attending college in Indiana, he met his wife, Kim, in Long Beach, California. They were married in 1997, and now have three children, Connor, Cole and Ryan Kimberly.

Dr. Worden earned his dental degree at the University of the Pacific, Arthur A. Dugoni School of Dentistry in 2001. He was selected by the prestigious Children's Hospital in Cincinnati to complete his residency in pediatric dentistry. In 2003, he finished the program as a board eligible pediatric specialist.

After returning to Long Beach, Dr. Worden was privileged to come into and eventually take over his father-in-law's, Dr. Beebe, pediatric dental practice. It is source of great satisfaction that this long-standing practice remains in the family.

Outside of work, Dr. Bill is passionate about golf, coaching youth soccer and spending time with his family.
