 Trustindex verifies that the original source of the review is Google. Shock wave therapy is the most effective method to relief tennis elbow, tendinitis, and pain from muscular overuse.  Can’t recommend this method or Dr Ryan more!! Simply the best.

 Trustindex verifies that the original source of the review is Google. Dr. Ryan Bonnebaum is amazing! I had a great deal of pain in my neck and upper back from trauma. In two months, the pain was gone. I also have my daughter seeing him also for her back pain. I can’t give enough praise to him. Thank you Dr. Ryan!

 Trustindex verifies that the original source of the review is Google. I absolutely love going to Spine Body Collective for adjustments. Ryan is really kind and gentle. He listens to my concerns and makes me feel really comfortable. I highly recommend Spine Body Collective with Ryan for great care! He also provided me with exercises and stretches I can do at home to help reduce pain and mobility which I am loving.
