DR. AARON THOMPSON, PT, DPT
He/Him/His
PHYSICAL THERAPIST
Dr. Aaron Thompson has a passion for helping individuals return to the activities they love through evidence-based orthopedic and sports rehabilitation. He brings a thoughtful, individualized approach to care that emphasizes functional strength, movement quality, and long-term performance.
In his own words:
"As a licensed physical therapist with a passion for the outdoors, I specialize in helping active individuals and athletes return to their fields of play, the mountains, trails, and everything in between. I hold a Doctorate in Physical Therapy from Arcadia University and have experience in outpatient orthopedics, strength and conditioning, and integrated wellness settings like the YMCA.
I focus on evidence-based rehab tailored to runners, cyclists, outdoor athletes, and high school athletes across a range of sports. As a former CrossFit coach with a background in strength and conditioning, I bring a performance-based lens to rehab—emphasizing functional movement, durability, and long-term athletic development. Whether it’s rehabbing from injury or optimizing movement for adventure, I believe physical therapy should support the lifestyle you live for."
His primary interest is strength and performance training for our athletes helping them get back to what they truly want to do.
Outside the clinic, you’ll catch him riding the trails of Galbraith and exploring Bellingham on his mountain bike or having great adventures with his family!
