Dr. Hagen has been wonderful to work with. He is very knowledgeable and nice to work with. I sought treatment with him because 9 months after being being hit by a car while cycling, I was still having neck pain, headaches and numbness down one arm. He was able to quickly identify the root causes and set a treatment pan that provided pain relief and improved range of motion within weeks. He has also taught me stretching and strengthening exercises to help the issues.
