"I enjoy building relationships with my patients and helping them regain function and maintain their quality of life. I am dedicated to helping each individual understand his or her condition and treatment options, both surgical and non-surgical. I strive to help my patients achieve their desired level of function and pain relief whether they are elite athletes, weekend warriors or older adults."

Dr. Bader grew up in the Bay Area and attended the University of California, Davis, where he majored in neurobiology, physiology and behavior and graduated with the highest honors. Dr. Bader went on to complete medical school at the University of California, Davis, and completed his Orthopedic Residency at Harbor-UCLA Medical Center in Los Angeles.

Dr. Bader then completed a one-year fellowship in Sports Medicine, Knee, Shoulder and Hip Arthroscopy at the world-renowned Cleveland Clinic Foundation. While at the Cleveland Clinic, he gained extensive experience as a team physician for local high schools, club teams and Cleveland State University. He was also a member of the medical team for the Cleveland Indians, Cleveland Cavaliers, Cleveland Browns and the NFL Combine, gaining experience in the management and care of athletes at all levels.

After his fellowship, Dr. Bader returned with his wife and three children to settle in the East Bay area. For the past five years, he has served as Chief of Orthopedic Surgery at Contra Costa Regional Medical Center in Martinez.
