Alejandro Cerna

PT, DPT, FAFS

Alex, a San Diego native, received his Bachelor of Science in Kinesiology and Doctor of Physical Therapy from San Diego State University. In 2018, Alex decided to take his passion for 3 dimensional biomechanics to a higher level, as he spent 42 weeks earning his Fellowship in Applied Functional Science (FAFS) and 3D MAPS, from the Gray Institute for Functional Transformation. His clinical experiences have allowed him to work with a wide spectrum of patients, including children, geriatrics, orthopedic injuries, as well as D1 and professional athletes. He has taken his passion for functional rehabilitation into the academic setting, and is an assistant instructor for future Physical Therapists in Movement Science at the University of St. Augustine for Health Sciences.

In his spare time, Alex enjoys playing recreational sports, surfing, backpacking, and spending quality time with his daughter.

Kevin Carey

PT, DPT, FAFS

Kevin is originally from Fairfield, Connecticut but moved to San Diego to attend the University of San Diego where he received his Bachelors in Marketing. His passion for physical therapy began when he first came to G3 as a patient for hip impingement that prevented him from playing hockey without injury. Once treated, Kevin was able to continue to do the things he loves; hockey, surfing and snowboarding while remaining pain free. Kevin’s love for physical therapy continued when he began working as a physical therapy aide at G3 from 2014-2016. In 2016, Kevin started his DPT program at San Diego State University and finished his last round of clinicals working as a student here at G3. He is now hired as a full time physical therapist and has come full circle from patient to physical therapist all within the G3 family!
