Preston Donjon spent his childhood in St. Louis, Missouri before joining the United States Air Force Reserves in 2013. During his service, Preston was deployed to Afghanistan. Upon returning to Missouri, he felt a strong desire to help others improve their quality of life and movement. This led him to pursue his Health Studies degree from the University of Central Missouri, where he met his wife, Emily. Following graduation, he moved to North Carolina to attend High Point University where he received his doctorate in physical therapy in 2022. After graduation, Preston and Emily began traveling as contract physical therapists until September of 2024 when they joined JCMG Physical Therapy.
