Leanne Atchison
Patient Care Coordinator – South Fort Collins, Loveland, Loveland-Orchards

I was born and raised in Western Nebraska. I moved after High School to attend college at the University of Nebraska at Kearney. I have a 10 year old daughter named Dylan, and a six year old son named Miles. I moved to the Fort Collins area earlier this year. Away from work I enjoy live music, wakeboarding, being outside and spending time with my family. And FOOTBALL!! Especially cheering on the Nebraska Cornhuskers!


I am very happy for a chance to review RMPT. After a bone breaking fall , on hard ground, they were able to rid me of the pain and make it possible for me to walk again. As i have no car, Stacey worked carefully to coordinate my rides and available appointments and Kaleb’s unusual expertise, patience, and encouragement, gave me a new start in only 3 months. What a joy to work with such professionals!

Rocky Mountain PT has turned out to be an excellent choice in doing my therapy. From the ease of scheduling through the office to the way they make you feel throughout the entire process is great. I had Derrick for the majority of my appointments and he was able to help alleviate so many of the post surgery issues I was having. He was always open ears to how I was feeling and I could tell he has a passion for really trying to "help". From one small business to another its nice to see a company that truly cares. Thank You Derrick!
