After nearly two decades at St. John’s, my team and I have now fully transitioned and are thriving at USC. We are proud to share that our entire surgical team came over together, and our practice is stronger than ever.
With our main office in Beverly Hills and our surgeries in Arcadia, we now provide outstanding hip and knee replacement care across Southern California. Both facilities offer a professional and seasoned experience—with exceptional outcomes and personalized care.
While I serve as a Clinical Professor at the Keck School of Medicine of USC, my teaching is centered in the classroom and conference room—not in the operating room. I continue to personally perform all surgeries and supervise every patient’s care.
Teaching has been one of the most energizing parts of this new chapter. Working with students has challenged me with their sharp questions, inspired me with their idealism and commitment to helping patients, and impressed me with their work ethic on research projects. It’s been a refreshing reminder of why I chose this path when I graduated from Stanford Medical School 30 years ago.
Surrounded by thoughtful faculty colleagues across specialties, I’ve found this to be an environment that constantly sparks new ideas for ever improving patient care. My years at St. John’s will always hold meaning, but this new chapter at USC marks a clear and confident step forward. Thank you for your continued trust and support.
