Blake D. Christensen D.O.

Dr. Blake Christensen of Oklahoma Pain Centers

Board Certified, Fellowship Trained Interventional Pain Management

I am from the Deer Creek/Edmond area and am proud to be a fifth generation Oklahoman. I earned my undergraduate degree from the University of Oklahoma where I competed on the wrestling team and graduated Magna cum Laude. I then attended OSU College of Osteopathic Medicine and earned my Doctor of Osteopathy Degree. I completed my residency in Anesthesiology at the University of Oklahoma Health Sciences Center. After residency, I completed an ACGME approved fellowship in Interventional Pain Management in Chicago, Illinois with a large, dynamic group of Interventional Pain faculty associated with the John H. Stroger and Rush Hospital systems. I am Board Certified in both Anesthesia and Pain Medicine. I am fellowship trained in interventional pain management. In 2016, I returned to my hometown to practice Interventional Pain Management. I opened the Oklahoma Pain Treatment Centers and hired a staff of qualified medical assistants and professionals who share my vision. It is my goal to provide the highest standard of care to all of my patients and effectively communicate treatment plans with each patient’s referring physician. My specialty is Interventional Pain Management with a focus on interventional techniques and medical management of complex pain syndromes. While approaching pain management through a conservative multimodal approach, I use the most current techniques to help reintroduce patients back to the healthy, functional, pain-free life they previously enjoyed. I believe it is possible to #LivePainFree.  I thoroughly enjoy working with my patients to manage and reduce their pain.  It is my privilege to serve as your Pain Treatment Physician.
