Dr. Ilya Igolnikov is a dual-board-certified, fellowship-trained physical medicine and rehabilitation specialist (physiatrist). He specializes in nonsurgical care of the musculoskeletal system, as well as the spine, including a wide array of spine, peripheral joint, and musculoskeletal injuries and conditions. He is seeing patients at the Boulder location.

As a physiatrist, Dr. Igolnikov’s focus is on treating the underlying biomechanical, nutritional, rheumatologic, or other medical problems that may contribute to an injury to help his patients get the best functional outcome long-term. 

After finishing his undergraduate studies at the University of Colorado Boulder, Dr. Igolnikov completed a master’s degree in advanced chemistry at the University of Colorado-Denver with a thesis on how the antioxidant Resveratrol can affect cancer progression. Dr. Igolnikov then went on to medical school at Tel Aviv University. He completed his residency at Temple University Hospital/Moss Rehabilitation Hospital, where he was elected to be chief resident and garnered the award for resident educator of the year. He prides himself on taking the time to educate his patients to be more involved in their own care so they can be better advocates for themselves. Afterwards, he went on to complete a fellowship in musculoskeletal sports and spine medicine at the renowned University of Pennsylvania, the oldest hospital in the country.

Immediately following training, he became the assistant fellowship director at the University of Pennsylvania’s musculoskeletal, sports, and spine fellowship, where he became known for developing a diagnostic ultrasound program. He also teaches diagnostic and interventional ultrasound techniques at conferences nationally. In 2021, he moved back to Boulder, Colorado, to continue his academic pursuits but also his love for alpine skiing, rock climbing, and other outdoor adventures.
