Welcome to the practice of William Sheppard, MD, MPH, in Santa Monica, California. As an expert orthopedic & neurological spine surgeon, I and my staff use our years of spine surgery experience to deliver lasting pain relief, improved mobility, and a better quality of life to our patients.

Our office is inside the UCLA Health Spine Center. Ample on-site parking is available, and we offer cutting-edge diagnostics, including X-rays, MRIs, and CT scans.

The collaborative treatment process we use emphasizes patient participation and feedback. Instead of making blanket treatment recommendations, we dedicate time to our patients, listening to their symptoms, concerns, and goals. We use that information to develop outcome-oriented treatment plans.

People from all over Los Angeles visit us for our spine expertise. We regularly diagnose and treat common back problems, including degenerative spinal disorders like scoliosis, spinal stenosis, and spinal disc herniation.

Rather than relying on open surgery, we primarily recommend minimally invasive surgery. This looks different for each patient, but I specialize in several techniques, including cervical spine surgery, cervical spine replacement, lumbar spine surgery, laminoplasty, robotic surgery, and endoscopic spine surgery.

Minimally invasive spine surgery provides various benefits. It requires less anesthesia, causes less blood loss, and uses smaller incisions that heal quickly. It allows patients to return to their lives quicker and risks significantly fewer complications.

Don’t let back or neck problems keep you from living your best life. Take the first step toward pain relief today. Call the practice of William Sheppard, MD, to schedule a new-patient appointment, or book your visit online.
