First Vice President: Ronald A. Navarro, M.D.

I was raised in the Los Angeles harbor area of Wilmington and attended the Los Angeles public school system. As a child, it was my dream to become an orthopedist/sports medicine specialist (I even wrote about it in my high school autobiography). Today, I work in the same community where I was raised. A board-certified orthopedic surgeon, I have more than 23 years of surgical experience in the operating room. My primary surgical and orthopedic training was at Harbor-UCLA Medical Center. I completed a post-residency fellowship program in sports medicine, arthroscopy, and specialized shoulder surgery at the University of Pittsburgh, and I now have more than 17 years of specialization in shoulder surgery, orthopedic sports medicine, and arthroscopy. I enjoy research especially in my subspecialty areas of interest: shoulder surgery, cartilage restoration, and orthopedic sports medicine.

My role at Kaiser Permanente is that of Regional Chief of Orthopaedic Surgery in the Southern California region, which means I help manage orthopaedic services from San Diego to Santa Barbara. I also help manage all of the perioperative services at the Kaiser Permanente South Bay Medical Center.
