Erin Connelly


Erin Connelly was born and raised in Bryn Athyn, PA where she attended the Academy of the New Church Girls School. Throughout her life she participated in many athletic events such as gymnastics, dance, soccer, basketball, lacrosse, and spring board diving which inspired her to further her education in the health and athletic industry. In 2011 she completed her Bachelor of Science degree in Exercise & Sport Science from Coastal Carolina University in South Carolina. After graduation she worked in a physical therapy outpatient clinic as a physical therapist aide and receptionist where she found her true passion in life was to become a physical therapist with a specialty in manual therapy. Manual therapy inspired her because she found that the techniques gave positive healing results to patients while offering quality and individual healthcare. In 2012 she moved to Saint Augustine, FL where she completed her degree as a Doctor of Physical Therapy with a specialty in manual physical therapy in 2014. Erin has now Manual Therapy Certified specializing in manual techniques for the sub-cranial/cervical spine, thoraco-lumbar spine, sacro-iliac joint, extremities, and myofascial mobilization of the entire body. Outside of work her time is well spent with fitness/athletics, running with her rescued black lab, and cooking with her husband.
