JoAnne Bailey, PTA
Physical Therapist Assistant

JoAnne Bailey was raised in North Georgia where she and her family were very active members of the community both in North Georgia and their neighboring town of Chattanooga, TN.
She attended Carson-Newman University in Jefferson City, TN where she began a love of outdoors, hiking, kayaking, etc... And fostered her sense of adventure by participating in all the intramurals her schedule would allow and by being on the dance team for the football and basketball teams.
It was also at Carson Newman that JoAnne met her future husband, Lee, and where she discovered her passion for anatomy and physiology. She earned her bachelor's degree in physical education with an emphasis in Exercise Science. Realizing that she had a love for helping people she pursued further education at Walter States Community College where she received her PTA degree and license in 1997.
JoAnne and Lee were married in 1993, and their adventure began, eventually having 4 children, Max, Levi, Emma and Audrey. Her greatest joys have been exploring the world with her family while still staying active in the local community by teaching wellness classes at the local YMCA, serving at her local church and participating and leading in the local homeschool co-op.
After graduating with her PTA degree, she worked at a nursing home before she and Lee became parents. At that point, JoAnne took several years off to help raise their family as she served her family as a stay-at-home mom, and she homeschooled all 4 children through high school.
After the youngest was old enough, JoAnne felt a pull to get back to serving the community outside the home and renewed her license.
The past 5 years JoAnne has thoroughly enjoyed getting back to helping people heal from surgery, getting them back on their feet and making new friends along the way.
Now empty nester, Joanne and Lee love to travel, hike and seek adventure but the local community is still where their heart is.
