ATI

ATI Physical Therapy, founded in 1996 by physical therapist Greg Steil, is a leading national provider of outpatient rehabilitation services, headquartered in Bolingbrook, Illinois[1][2]. The company specializes in research-based physical therapy, workers' compensation rehabilitation, employer worksite solutions, sports medicine, home health, and specialty therapies[1]. ATI operates more than 860 clinic locations across the United States, making it one of the largest physical therapy providers in the country[2]. The company employs approximately 6,000 people and reported annual revenue of $713.6 million[1]. ATI is publicly traded under the ticker symbol ATIP, though it has recently faced delisting from the New York Stock Exchange due to regulatory compliance issues[1]. Despite financial challenges, ATI has maintained a strong reputation for clinical quality, earning an 'Exceptional' rating from the Center for Medicare and Medicaid Services (MIPS) for five consecutive years since the program's inception in 2019[1]. The company’s services are widely utilized by employers, insurers, and health systems, and it has established partnerships with municipalities and corporate clients to provide onsite and community-based care. ATI’s growth has been fueled by both organic expansion and strategic acquisitions, though there is no evidence of a current parent company or recent merger/acquisition activity. The company’s core differentiators include evidence-based treatment protocols, a large national footprint, and integrated care solutions that span preventive, acute, and chronic condition management. ATI’s real estate strategy focuses on accessible, community-based locations that support both walk-in and physician-referred patient populations. The company’s clinics are typically situated in retail centers, medical office buildings, and standalone facilities, with a emphasis on high-visibility, convenient access, and co-tenancy with complementary healthcare providers. ATI’s expansion has historically targeted both urban and suburban markets, with a focus on regions demonstrating population growth, employer density, and healthcare demand. While the company’s recent financial performance and stock exchange status indicate some operational challenges, its national scale, clinical reputation, and diversified service offerings position it as a significant player in the outpatient rehabilitation sector.
