Dr. Samuel Oltman


Expertise in athletic injuries and regenerative medicine


Dr. Samuel Oltman, an Oregon native and all-state athlete in football and track, graduated with a Bachelors of Science from Oregon State University in Exercise and Sport Science where he also played wide receiver for the Beavers football team. He attended the National College of Natural Medicine, graduating with his Naturopathic Doctorate (ND), and then completed a rigorous 2-year primary care residency at Grain Integrative Health in Southeast Portland. He has advanced training in pain management, orthopedics, and regenerative injection therapies.

At Oregon Regenerative Medicine Dr. Oltman brings his unique experience and expertise to serve patients’ needs in regenerative medicine and primary care. His emphasis on a holistic approach to joint health sets him apart from the majority of other orthopedic practitioners. As a former collegiate football player, Dr. Oltman brings personal experience and intellectual passion to the study and treatment of all forms of sport injuries, aging joints, and degenerative arthritis.

For athletes at risk for traumatic brain injuries, Dr. Oltman provides ImPACT testing, a comprehensive and holistic brain injury screening, evaluation, prevention and treatment program offered at Oregon Regenerative Medicine. Our comprehensive programs are designed for athletes at all levels of competition as well as anyone at risk for a brain injury.

Dr. Oltman treats patients with the underlying presumption that the body contains the wisdom to heal itself. He believes our bodies simply need the requisite inputs for enhanced healing and the removal of certain barriers that prevent healing. Dr. Oltman’s views symptoms not as aberrations to be suppressed but rather wise expressions of nature pointing to where imbalance lies.

Dr. Oltman is currently undertaking specialized training in musculoskeletal ultrasound diagnostics and guided injection techniques. When he is not treating patients or learning more about medicine, he enjoys skiing, bouldering, running, swimming, being in the forest, and laughing with friends and family.

Patients of all walks and stages of life are encouraged to schedule a consult, whether to address a specific pain or to establish primary care, building the foundation for a long and vibrant life.
