Pain Management Center

Through the combined expertise of a multidisciplinary team, the Columbia Pain Management Center provides comprehensive evaluation, diagnosis, and treatment of acute and chronic pain conditions. With interventional pain physicians and psychologists, we incorporate behavioral health strategies alongside procedural care. We also offer acupuncture, health coaching, and nutritional support for metabolic and obesity-related contributors to pain. Our approach integrates advanced interventional techniques, medication management, psychological support, and complementary therapies to optimize function and quality of life. 

Additionally, we offer consultation for select pediatric patients (ages 10–18) with complex pain conditions and/or persistent post-surgical pain. These cases are considered on an individual basis following careful review and in close collaboration with referring pediatric teams to ensure appropriate patient selection and coordinated care.
