Rheumatology Associates

What Rheumatology Associates does

Rheumatology Associates of Long Island (RALI) is a privately-held, physician-owned subspecialty rheumatology group practice founded in 1978 in Smithtown, New York. The practice diagnoses and treats rheumatic and musculoskeletal conditions including rheumatoid arthritis, psoriatic arthritis, osteoarthritis, lupus, ankylosing spondylitis, osteoporosis, scleroderma, gout, fibromyalgia, myositis, and other autoimmune disorders. RALI serves a general patient population across the New York metropolitan area and self-describes as the largest single subspecialty rheumatology group practice in the region, growing from two founding physicians to eight board-certified rheumatologists trained at institutions including the NIH, Mount Sinai, Columbia, Yale, and Stony Brook.

The practice's core technical infrastructure consists of on-site diagnostic and treatment capabilities co-located across its offices: a full-service laboratory, a digital X-ray system (used to identify joint space narrowing, bone sclerosis, calcification, and malalignment), bone densitometry (DEXA) scanning for osteoporosis detection at the Smithtown location, and an Infusion Therapy Suite at Smithtown for IV-administered biologic medications for rheumatoid and autoimmune disorders. Patient-facing digital tools include online appointment request forms, downloadable new-patient and RAPID forms, feedback submission, and an updated HIPAA privacy notice. Multiple physicians hold clinical academic appointments at Stony Brook University Hospital, and the practice participates in the Rheumatology Fellowship Program.

Revenue is generated through fee-for-service clinical care: in-person consultations, diagnostic imaging and lab services, and infusion therapy procedures, with payment collected at the time of service including co-pays. The practice participates in Medicare and most commercial insurance plans and accepts major credit cards (excluding American Express, and not cash). Patient acquisition relies primarily on referrals from primary care physicians (many insurers require specialist referrals), online presence, patient reviews and word of mouth, and in-network insurance participation. The practice operates four office locations (Smithtown headquarters, Port Jefferson Station, Melville, and Staten Island, with the Staten Island site operating as "Staten Island Arthritis & Rheumatology") and has grown entirely organically with no disclosed funding, private equity backing, or acquisitions.

Regional players

• Northwell Health: Largest health system on Long Island, operating multiple hospitals and physician practices across the same geography as RALI, including rheumatology services. Represents both an overlapping service provider and a potential partner given its regional dominance.
• Summit Health: Large multi-specialty physician group with significant New York and New Jersey presence, including rheumatology services. Comparable in multi-site ambulatory care delivery model but with broader specialty breadth than RALI.
• Stony Brook Medicine Rheumatology: Academic rheumatology practice affiliated with Stony Brook University Hospital, where several RALI physicians hold faculty appointments. Operates in the same Long Island geography with overlapping clinical scope and shared referral pathways.

Broad incumbents

• Hospital for Special Surgery (HSS): The leading U.S. hospital dedicated to orthopedic and rheumatologic care, headquartered in New York City. Operates a large rheumatology division treating the same conditions as RALI but at academic-medical-center scale and with inpatient and surgical capabilities RALI does not offer.
• Cleveland Clinic — Department of Rheumatology: National health system with a large rheumatology department that diagnoses and treats the same conditions as RALI, including infusion therapy and bone densitometry. Comparable clinical offering but embedded in a multi-specialty academic system.
• ColumbiaDoctors Rheumatology: Faculty practice of Columbia University Irving Medical Center with a rheumatology division serving the NY metro. Comparable clinical scope (RA, lupus, osteoporosis, infusion therapy) but anchored to a major academic medical center rather than an independent group.
• NYU Langone Health — Division of Rheumatology: Major New York academic health system with a dedicated rheumatology clinical and research division serving the same patient population as RALI in the NY metro, with broader institutional backing and clinical trial infrastructure.
• Mayo Clinic — Division of Rheumatology: National academic medical center with a dedicated rheumatology division providing the same core services as RALI (consultation, infusion, imaging, lab) at institutional scale, including clinical research and complex case management.

Direct peers

• Arthritis & Rheumatism Associates, P.C. One of the largest independent rheumatology specialty group practices in the United States, operating multiple offices in the Washington, D.C. metro area. Closely comparable to RALI in business model: subspecialty physician group with on-site infusion, lab, and imaging, focused exclusively on rheumatic diseases.
• Rheumatology Associates of New Jersey: Independent multi-physician rheumatology specialty practice serving northern New Jersey. Closely comparable to RALI in being a private subspecialty group focused on rheumatic disease care with on-site infusion and laboratory services.
