Your Goals Are Unique - Your Training Should Be Too

No more doing the same cookie-cutter workouts as everyone else.

Generic workout plans often lead to minimal results and decreased motivation

Improper form and technique can cause injuries and setbacks

Read what others are saying about their results

"Every session I felt truly cared for, listened to, and most of all, that both Andrew and Luke are always happy to see me. Thank you, AFI!”

Audrey Johnson

"Andrew and Luke are both PHD's in PT. They use their knowledge to help you regain your fitness by directly addressing the issues you have and designing a program to improve yourself."

Jeff Skeen

"Andrew P. did a great job strengthening & rehabilitating my son's shoulder after a dislocation. Our evaluation gave us a clear plan, how long it would take and specific costs. All of these things were met!"

Brenda DeVito

"I walked in with a limp and walked out without it! Dr Phillips and especially Dr Peterson worked with me on a plan to not only help me get back on track but also accountability when I was at home.”

Dave Paranteau

"Achilles and my trainer have been amazing! When I started my PT, I could barely use my left shoulder and had a limp due to my left knee. I’m pain free and my workouts are better than ever.

Gregory Watkins

"I started working with Andrew about 6 weeks ago and couldn't be happier with the progress. I decided to make an appointment when pain-free running turned to painful running turned to painful walking/standing."
