Dr. William Cullen

Meet Your Doctor

I have been through hell and back multiple times when it comes to injuries and have always been intrigued about the human body and how it works, and how to optimize potential to a human no matter the physical set back or flaw. I have experienced the frustration of bouncing between doctors and treatments, waiting for imaging results and diagnosis. I want to fix that for every patient that walks through my door. My purpose is to give the patient all of the tools to become independent with their health, whether it's the elderly or the athlete.

I had been having neck pain for the last year with no relief from PT.  Decided to look for a chiropractor and had received several recommendations  for Dr. Cullen.  Dr. Cullen was able to diagnose the problem and explained his treatment plan.   I was very impressed with his knowledge and felt totally confident in his care.  It was a wonderful feeling waking up one morning with no more pain.  I would highly recommend this practice and everyone in the office is very friendly and efficient.

My boyfriend has been complaining of significant low back pain for some time now so I suggested he see a chiropractor. He has a pretty physical job and lifts heavy weights on a regular basis. We found Dr. Cullen through the BCBS portal, did some research and decided to go with Advanced Chiropractic. I was able to get him a new patient appointment the same day I called and he walked out feeling great! He said Dr. Cullen was very knowledgeable and so helpful to him as well as his support staff. I highly recommend!

By far the best! Dr. Cullen genuinely cares about his patients, he helped me get back to normal after a severe disc injury playing ball. Any athletes in the DMV area look no further, Dr. Cullen literally has your back. Highly recommend 10/10! Since then, I have exclusively been going to see Dr. Cullen for all of my chiropractic needs. I highly recommend their practice because they are not "get in, get out doctors" that will try to sell you some plan of adjustments. They truly care in your health and their goal is to NOT see you in the office.
