“In November of 2014 I had major back surgery to insert a metal rod and attach my spine back together.My main crew at Foothills of Kacie, JJ, and Dillon provide a very competent and professional service to help me return to assuming a normal life style.I felt like I was in very good hands and could see results right away. I felt like they listened to me and always had answers and encouragement.

I would have to say that it wasn’t just the technical part of the recovery that was important but who they were as individuals and as human beings.They showed me that they cared for me as a person and my emotional needs as well. I would come back in the future to use their service if the need arises.”

“Following shoulder surgery the first part of February 2013, I began Physical Therapy at Foothills Sports Medicine on Kyrene Rd., Tempe (Formally Performance Physical Therapy), the second week of March, 2013. All therapy personnel, Carlos, Kacie, Crystal and Daniel have gone above and beyond to attend to my recovery. They have treated me like family and as if they are my personal trainers.

I have nothing but high regards for their professional demeanor during this extremely difficult time for me. They all have pushed me, and pushed me to the limit. It has all paid off! My Doctor advises that I am recovering at a faster rate than expected. All of that is due to the attention that I have had and continue to receive from everyone at the facility.

Thank you one and all!!”
