Dr. Tyler Smith, MD, is a Fellowship-Trained and Board-Certified Orthopedic Spine Surgeon, Spine Surgery Specialist, and the Founder of Sierra Spine Institute. Dr. Smith takes pride in providing the people of Roseville, California, and surrounding communities with the highest quality surgical and conservative care.

Dr. Smith focuses his practice exclusively on evaluating and treating conditions of the spine in adults and adolescents. He is widely regarded as an innovative thought leader in the field of minimally invasive spine surgery, and has published extensively in peer reviewed literature.

He has traveled the world teaching surgeons and lecturing on this groundbreaking technique. As a practiced Orthopedic Spine Surgeon, Spine Surgery Specialist, and health care professional, Dr. Smith feels he and his team have a clear obligation to provide patients with as much information about their care as possible.

“Informed patients simply make better decisions about treatment options and enjoy better outcomes,” he says.

Dr. Smith also has a healthy respect for surgery and believes it should be avoided (if possible). However, if your condition requires an operation, it should be done in a way that preserves uninvolved tissue as much as possible, otherwise known as minimally invasive.

Dr. Smith always takes a respectful and responsive approach. His sole mission is to alleviate your pain through personalized, high-quality care, and his goal is to get patients back to living their lives as quickly as possible.
