About Fiel Family & Sports

For over 20 years, Fiel Family & Sports Medicine has provided medical care from our family-friendly clinic in Tempe, AZ. Our team is experts in Family Practice/Medicare-covered services, Muscular Skeletal Injuries, Sports Medicine, Wellness Exams, OrthoBiologics, and Women’s Health. We are also proud to be one of Arizona’s leaders performing clinical trials directly from our office.

Our compassionate and experienced practitioners use leading diagnostic technology and testing to treat various medical conditions and injuries. Unlike many practices, we have in-office ultrasound and phlebotomist and pride ourselves on our accuracy and timely results. We also offer Telemedicine, utilizing easy-to-use but leading technology in that field.

Dr. Fiel’s expertise in Sports Medicine spans beyond just his practice. He has proudly served as a Team Physician for the Phoenix Suns and Milwaukee Brewers, providing medical care and treatment for some top athletes (and their families) in professional sports.

My shoulder pain was a lot like having a migraine headache. It was constant and kept me up all night. Dr. Fiel, or as I now refer to him, “Dr. Fiel-Good,” put me at ease and made the injection painless and easy. I now have my quality of life back for the first time in years, free of pain.

It was a very relaxed and down to earth experience in the clinic…the injection was over before I realized it had even begun. Not only can I finally sleep on my shoulder for the first time in 6 months, I am ready to get back to winning some team-ropings!

I just wanted to thank you for your kindness and professionalism when I had my regenerative therapy injections in my hip. It could not have been a better experience. But most of all thank you sooo much for taking my pain away. I am almost 5 weeks post and it gets better every day.
