  • "End to my Seizures

    I began having seizures after an injury to my upper neck. I saw a neurologist who prescribed Neurontin. After seeing Dr. Petersen for just a few visits my seizures stopped and I was able to stop the medication; I am now a wellness patient and will continue to be seizure free! He is the best chiropractor I’ve ever been to!"

  • "Family Wellness

    Our Family has trusted our spinal care to Dr. Brian for about 20 years now. He and his staff really care about the health and wellbeing of our entire family. Whether it’s an injury we need help recovering from or just maintaining health through regular adjustments, we can always count on Dr. Brian to give quality care. He was even the first stop on the way home from the hospital for each of our 4 children as newborns. Now, that’s trust! If you’re looking for a chiropractic office with people who will truly care about the whole body health of your loved ones then Petersen Chiropractic is the place for you!"

  • "Chronic Pain

    My hat is off to Dr. Petersen. I have been paralyzed over 34 years. My other doctors turned me against chiropractic due to the fact I have osteoperosis and arthritis. Instead, I’ve had a wide assortment of pain medications for many years. My sister, who cares for me now, insisted I see her chiropractor, Dr. Petersen. He looked at my x-rays and said he thought he could help me. I thought “Oh, Yeah!” What a wonderful surprise to at last be off constant pain medication! I have no more migraines or back pain and I sleep well now. My stroke specialist is very pleased. I am back to my artistic pursuits and am enjoying improved health. Thank you Dr. Brian."

  • "Health Assurance

    Dr. Brian, I must tell you how important your chiropractic care is to my overall health and well-being. My late husband Neal Mitchell and I became your patients 10 years ago. You made his life much more bearable during his final illness. What a blessing! Although I am now 80 years old, I am still playing accordian and electric keyboard on a professional schedule. Due to your spinal adjustments, I am able to function with ease and without pain. Hallelujah!!! Thank you for being here for me and the Belfair community."

  • "No Surgery!

    Thank you so much for saving me from surgery. I was being sent for possible surgery and after only four visits with you I have pain-free movement and NO SURGERY!!! You are the best, I will recommend anyone who suffers with back, neck or just any health problem to see what a difference a few visits can make. Thanks again! I am so grateful."

  • "Improved Health and Wellness

    Our family of 8 has been seeing Dr. Petersen for years now for improved health & wellness. We have seen great results with all of our children including amazing changes with our daughter’s Cerebral Palsy. When one child was in the hospital, Dr. Petersen traveled to Tacoma to see her and relieve her headaches with an adjustment. He referred me for a hip replacement and went in the operating room with me, holding my hand along the way. It’s wonderful to have a family doctor so committed and so caring… We’ve never been healthier."

  • "It was Amazing!

    “Our 5 year old son P.J. was in the hospital for one week. He could not walk at all. After numerous tests including blood work, x-rays and an MRI, they still didn’t know what was wrong and he was not responding to the medications or the traction. We finally carried him in to Dr. Brian’s office and within two adjustments he was back to running normally. IT WAS AMAZING !”"
