When she is not in the clinic, you can find her mountain biking or trail running with her lab and husband.
Dr. Natasha Hastings DPT, CSCS, CF-L1
Athletic Edge Physical Therapy of San Diego, CA was founded on the drive to help people achieve their health and fitness goals. Dr. Natasha Hastings is a Doctor of Physical Therapy, with an extensive history of sport involvement. She specializes in Pelvic Floor Physical Therapy, orthopedic & sports rehab, combined with strength and conditioning coaching.
Dr. Hastings is from the East Coast, originating from Northeast, PA. She grew up in a rural town, started playing soccer at 6, later basketball, and then lacrosse in college & post-college. She was a travel PT for a bit, treating in North Carolina, NOVA (northern VA), and now sunny San Diego, CA. Dr. Hastings loves the outdoors: hiking, snowboarding, attending her local CrossFit box, and hanging out with husband and 2 Vizslas.
While working her first several years in the general orthopedic setting, Dr. Hastings noticed patients were treated more like a number than an actual human being. AEPT was developed in 2019 to better serve clients and give them the one-on-one attention they need.
Dr. Alyssa Dionisio DPT
Alyssa is a Doctor of Physical Therapy who has a passion for orthopedic and sports rehabilitation, strength and conditioning, and helping active individuals return to the activities they love. Originally from Philadelphia, she earned her DPT from Thomas Jefferson University.
Alyssa has experience working with a variety of orthopedic and athletic populations, with a particular interest in ACL rehabilitation, post-operative knee recovery, and return-to-sport training. She believes physical therapy should go beyond simply getting out of pain—it should help people build the strength, confidence, and capacity to return to the things they enjoy. Her approach combines individualized programming, hands on cuing and manual techniques, strength and conditioning principles, movement assessment, and patient education.
Outside of the clinic, Alyssa enjoys running, strength training, playing with her dog, and playing soccer for fun.
