What ATI Physical Therapy does
ATI Physical Therapy is an outpatient orthopedic rehabilitation provider operating over 850 clinic locations across 24 U.S. states, employing approximately 6,000-7,000 clinicians and support staff. Founded in 1996 and headquartered in Downers Grove, Illinois, the company delivers physical therapy for musculoskeletal conditions including back, knee, shoulder, hip, neck, and pelvic issues, as well as specialty programs in hand therapy, vestibular rehabilitation, sports medicine, aquatic therapy, concussion management, oncology rehabilitation, and workers' compensation rehabilitation. Patients access care primarily through self-referral under many insurance plans, with appointments typically available within 24-48 hours.
The company's product platform combines in-clinic visits with the ATI CONNECT virtual practice for online physical therapy and a hybrid care model, plus Remote Therapeutic Monitoring as an add-on service. Underlying infrastructure is the proprietary ATI EHR v1.0, which received ONC-ACB 2015 Cures Update Edition certification in December 2025, supporting clinical documentation, transitions of care, clinical quality measures, and Electronic Health Information export. Supporting tools include the ATI Payment Portal (accepting Apple Pay, Google Pay, PayPal, Venmo, and standard payment methods) and integrations with Dynamic Health IT and MaxMD Direct for interoperability and secure messaging.
ATI generates revenue primarily through fee-for-service outpatient physical therapy billed across a broad mix of accepted insurance plans, supplemented by workers' compensation case management, the F.I.R.S.T. work conditioning program, and enterprise sports medicine contracts with over 150 organizations serving 50,000+ athletes annually. Following its August 2025 take-private transaction with Knighthead Capital Management and Marathon Asset Management at a $523.3 million enterprise value, the company operates outside public-market scrutiny with stated intent to focus on organic expansion and quality improvements.
