Sara Asadoorian, LAc., CSCS
Sara Asadoorian is the owner/operator of Advantage Sports Acupuncture. She’s originally from Massachusetts but moved to Arizona in 2006 to continue her education and pursue her career. Sara knew she wanted to work in the sports medicine field since the first time she sprained her ankle and had to attend physical therapy as a young athlete. She grew up playing competitive sports, so she spent a fair amount of time in PT clinics and training rooms over the years. When she’s not working, you can find her on a golf course somewhere in the east valley or at the park with her husband, Michael and their dog, Archie. Sara is a Licensed Acupuncturist; Certified Fascial Stretch Specialist – Level 3 Medical; Certified Strength and Conditioning Specialist; and Corrective Exercise Specialist.
