Before contacting us, please understand:
Stem cell and PRP injections for musculoskeletal conditions are NOT FDA APPROVED. While research has shown that stem cell and PRP therapy may offer benefits to patients with orthopedic issues, many of these same studies conclude that further evaluation is needed from large, well-controlled clinical trials to verify possible benefits. We only treat orthopedic issues. We do not treat disease. We do not offer IV treatments.

We do not promise stem cell or PRP therapy as a cure for any condition. We provide stem cell and PRP therapy as a same day procedure, without manipulation, stimulation, or culturing of cells. Stem Cell and PRP therapy does not work for everyone. Results achieved by some patients may not be typical for other patients. There are no guarantees that this treatment will help you. All information on this website including reference to current research journals is for educational purposes only. There is controversy in the medical community about whether umbilical cord blood stem cells are alive or dead. You are encouraged to speak with your private medical doctor to help you decide if our treatments might be beneficial for you.

There is controversy in the medical community about umbilical cord blood stem cells. Some insist that the injectable solution contains abundant live umbilical cord blood stem cells. Some suggest that the stem cells are not alive. Some research shows that stem cells may release cytokines and growth factors that awaken native stem cells. We also use PRP and bone marrow depending on the patient’s pathology and requirements. We are in the process of doing a large study on cord blood stem cells to ascertain which treatments are the most successful. Short term results show cord blood stem cells and bone marrow concentrate to be statistically equal in efficacy on the scales we record..
