Will Seifert, MAT, ATC, is a certified Athletic Trainer at Cornerstone Clinics specializing in sports rehabilitation, injury prevention, and return-to-activity care. Prior to joining Cornerstone, Will worked in both collegiate and professional soccer, including two seasons as the Athletic Trainer for Loyola University Chicago Men’s Soccer, as well as roles with Real Salt Lake, North Carolina FC, and Coastal Carolina University.
Will earned his Master’s Degree in Athletic Training from the University of Arkansas in 2022 after completing extensive clinical education and national board certification. Athletic Trainers are licensed healthcare professionals trained in injury prevention, evaluation, rehabilitation, and return-to-activity planning. Will’s training allows him to guide patients through the full recovery process—from the initial injury through rebuilding strength, restoring movement, and safely returning to sport or daily activity.
At Cornerstone Clinics Will works with active individuals of all ages and backgrounds. His clinical approach emphasizes movement quality, progressive strength training, and patient education to support long-term recovery and injury resilience. He collaborates closely with the chiropractic and rehabilitation team to help patients move better, reduce pain, and return confidently to the activities they value most.
Will is passionate about building strong clinician-patient relationships and believes that successful rehabilitation depends on trust, communication, and individualized care. Outside the clinic, he enjoys spending time along the Chicago lakefront, attending live music events, watching soccer and basketball, and staying active.
“I want to see people moving as quickly as possible—and smiling as quickly as possible.”
