Jill Sippos, MPT


Jill Sippos graduated in 1999 with her Masters in Physical Therapy from Chatham College in Pittsburgh, Pennsylvania. During her schooling, Jill had an amazing opportunity to travel to Deschapelle, Haiti with a small group of students and professors. During that trip, she had a life changing experience treating patients with little to no resources. This experience allowed her to be creative in using her newly acquired physical therapy skills.
After graduation Jill stayed in Pennsylvania for three years working in an outpatient clinic and the local hospital. At that time, Jill and her husband, Rich decided to make a change and move to the beautiful Utah Mountains. For 11 years they called Utah their home and Jill worked in the sub-acute rehabilitation field, assisting patients in healing from traumatic injuries, surgeries and illness.
In August 2014, Jill, Rich and their two daughters, Natalie and Sophia realized their dream of moving to beautiful Bozeman, Montana. Jill began working at Pro Physio in September 2014. She is skilled in the evaluation and treatment of musculoskeletal injuries. She is certified in Selective Functional Movement Assessment and a certified RockTape provider.
