Dr. Trahan has been nothing short of amazing treating my chronic pain. She and her staff make every visit comfortable and enjoyable. I HIGHLY recommend her!

I went to see Dr. Sarah Trahan with a shoulder/back problem that I had been dealing with for about a year. I was taking painkillers constantly and sleep was a problem. I had tried physio, muscle relaxants, Chiropractor, acupuncture, dry needling and numerous other treatments but none of them worked at all. After a thorough assessment we decided to go ahead with a number of shots into the region that was bothering me. It was a combination of a couple of drugs which I forget the name of. Within a couple of days the pain was gone and has been that way for the past 6 weeks. I've has a couple of twinges but they've resolved themselves and I continue to do the physio exercises she gave me. She followed up with a couple of phone calls to see how I was doing. Overall excellent treatment and care

I have chronic pain on my upper shoulders and neck for many years. I went to Neil Riordan Center for Regenerative Medicine because I want to see if there is an innovative solution for my pain besides taking pain medication. I saw Dr. Mareshah Dunning and she took an intuitive approach toward treatment and patient care. Dr. Dunning was genuine and respectful with my issues and went above and beyond to help me find the root cause of my pain. Dr. Dunning immediately requested blood tests and MRI that gave me the big picture of my chronic pain. Dr. Dunning found thyroid issues and decompress cervical disc. She ordered physical therapy for the 1st step into treating my pains and some additional steps in the treatment plans. Dr. Dunning is a skilled physician and I’m very thankful to have her as my doctor. I give Dr. Dunning 10 stars!!
