Ernest H. Sponzilli, MD

Dr. Sponzilli feels a genuine honor to have the opportunity to serve you. As a reflection of this, he has been awarded three separate board certifications to offer you exceptional care and expertise. Experience is critical when performing precision percutaneous spinal interventions and incisionless/ bloodless surgeries.

Dr. Sponzilli esteems himself as one of the highest volume providers of intervention spine care in northern California. Specializing in interventional pain care management, Dr. S has successfully performed over 1000 interventional pain procedures annually for the past 15 years since beginning his career at California Orthopedics & Spine in 1999. His special clinical skills include neurodiagnostics, peripheral nerve and joint blocks, cervical thoracic and lumbar epidural steroid injections, radiofrequency desensitization, fracture augmentation, percutaneous discectomy, thermal annuloplasty, and spinal stimulator implantation.

Dr. Sponzilli’s current research interest centers on novel regenerative therapies involving the use of advanced orthobiologic therapies, including IRAP1, PRP, BMAC, and ADSC for the treatment of arthritis, tendinosis, and degenerative disease. While these treatments can play a role in one’s recovery Dr. Sponzilli firmly believes in taking a broader whole life perspective identifying modifiable lifestyle factors that contribute to the development of injury and disease.

Dr. Sponzilli is a native of the bay area and lives with his wife and four young children.
