I met Tammy while on a random trip to Arizona. In striking up a conversation on Stem Cell injections and PRP I was amazed at her knowledge and passion on the subject. Once I had my MRI results I sent them right away to her and she followed up with additional critical information. My chiropractor also spoke to her and confirmed my choice that Tammy was an excellent choice. The surgery went smoothly and I am very amazed that my back has not given me any issues in the two months since. It is a huge blessing and I am very grateful.
