Roger Kasendorf, DO, is a board-certified osteopathic physician and physiatrist working in pain management, physical medicine, and rehabilitation.

His procedures include trigger point, joint, spinal, facet, and hyaluronic acid injections. He also uses Botox for migraines and muscle spasticity and relies on EMG and musculoskeletal ultrasound for diagnostic evaluation. His treatment planning considers how tendons, ligaments, joints, muscles, bones, nerves, and the brain function together.
