Our Physicians

physicians at Los Angeles Orthopedic InstituteOur doctors make the difference at Los Angeles Orthopaedic Institute. Every physician has completed a Fellowship and years of training in his or her specialty area. The high level of knowledge and experience assures that  patients receive expert care from our practice.

Orthopaedists Domenick J. Sisto, MD, Gregg R. Sobeck, MD, Richard E. Nussbaum, MD, Jonathan D. Botts, MD, Ehsan Saadat, MD, and podiatrist Nasim Kalhor, DPM, are trained in both surgical and non-surgical treatments, including minimally invasive surgery, joint replacement surgery, and our specially developed, non-surgical treatment regimen. Refined during years of research and supervised by our physician assistants and athletic trainers Coury Clemens and Nikki Sisto, our non-surgical treatment regimen combines exercise, nutrition, medication, and bracing to reduce pain, build muscle, and ease recovery. LAOI’s non-surgical treatment regimen enables most patients to return to an active, healthy lifestyle without surgery.
