She is a certified pilates teacher with over 400 hours of training in the STOTT method with a focus in rehabilitation and has taught yoga nationally to students of all ages for 10 years.

Christina Kernan-Donley
PMA Certified Pilates Instructor
Polestar© Pilates Pactitioner

Christina first discovered Pilates while at physical therapy recovering from 2 back surgeries. Her physical therapist at the time had a small amount of Pilates equipment, and though she never experienced Pilates during her physical therapy sessions, she was introduced to the importance of core control. Always keeping Pilates in the back of her mind, Christina completed her physical therapy and then continued to use swimming as her sole source of exercise due to some residual weakness in her right leg; traditional forms of exercise seemed almost impossible due to these symptoms. 3 years later, Christina was still frustrated with her exercise restrictions and finally decided to pursue Pilates. She noticed huge improvements in her strength and function after just a short time, and the rest is history! Christina’s love for Pilates led her to complete the Polestar Pilates teacher training program in 2017 and she is now focused on helping others who think they cannot accomplish their goals due to an injury.

Christina and her husband Curtis enjoy spending time doing any outdoor activity possible with their 4 children. When outside the Pilates studio, you will likely find Christina playing “chauffeur” to her kids, going from 1 school activity to the next.
