Lance M. Tigyer, D.O.

Lance M. Tigyer, D.O.

Board Certified Orthopedic Spine Surgeon

Board certified by the American Osteopathic Board of Orthopedic Surgery, I specialize in the diagnosis and treatment of surgical and non-surgical spine disorders. I am an expert in treating spine conditions such as spinal stenosis, cervical and lumbar disc herniations, sciatica, degenerative disc disease, arthritis of the spine, fractures, adult scoliosis ,continued pain after spine surgery and many others. I provide numerous conservative treatments such as epidural injections, facet injections, sacroiliac joint injections and physical therapy for my patients that do not require surgery: however if surgery is required I provide expert care with minimally invasive techniques to ensure the best possible result. When I am not treating my patients, I enjoy traveling and spending time with my wife and three children.
