Catherine Leng was born in Houston, Texas as an only child. She has a lot of Texas pride and love visiting her parents, whom she is very close to.  The majority of her extended family are in Taiwan, whom she loves to visit once or twice a year. Catherine's major (and most expensive) hobby is travel. She has travelled to over thirty countries and hopes to add to this number every year.

Catherine was given the privilege of studying Osteopathic Medicine at Touro University after she completed her Economics Degree at Emory University. She immediately fell in love with the Golden State and knew that she would have to return after graduating from her Family Medicine residency in Connecticut.

She met her husband at residency the first day of orientation and they have now been happily married since December of 2016. they are both proud to be practicing physicians at Kaiser Permanente in the Central Valley and are blessed to return to California to serve its population. 

David Duncan, DO, Pioneer, COM 2001

David Duncan

Dr. David Duncan initially joined the US Navy through the Health Professions Scholarship Program, and upon graduating from family medicine internship went to flight school and aviation medicine, deploying aboard the USS Kitty Hawk stationed in Japan, and was part of the initial launch of Operation Iraqi Freedom. After two years he returned to complete Family Medicine residency in Bremerton, WA, and was again stationed in Japan as a staff physician. David transitioned to the US Public Health Service and served as Senior Medical Executive and Flight Surgeon for District 11 with the Coast Guard, and most recently transferred to work with the Federal Bureau of Prisons as Clinical Director of FCI Dublin, CA. He just returned from a deployment managing a group of 200 dialysis patients evacuated from the Virgin Islands in the recent hurricanes. Working with the Armed Forces has allowed me the privilege to serve those who put their lives on the line for our country, but even more rewarding has been helping the truly underserved inmate population that so often is neglected.
