Great Lakes Center of Rheumatology

What Great Lakes Center of Rheumatology does

Great Lakes Center of Rheumatology (GLCOR) is a privately held, single-site rheumatology specialty practice headquartered at 4052 Legacy Parkway, Suite 200, Lansing, Michigan. Founded in 2016, the practice is led by Dr. Joshua P. June, DO and Dr. Iyad Al-Shwaf, MD, supported by a team of physician assistants and a nurse practitioner. Per the firm's own materials, GLCOR is the largest privately owned rheumatology practice in Michigan, treating a broad range of rheumatic and musculoskeletal conditions including rheumatoid arthritis, systemic lupus, psoriatic arthritis, ankylosing spondylitis, gout, fibromyalgia, osteoarthritis, and osteoporosis. Patient acquisition is driven by primary-care and specialist referrals, direct phone/website inquiries, and community engagement, with services delivered exclusively at the Lansing office.

The practice operates a vertically integrated care stack that combines traditional office-based rheumatology with two non-consult revenue and service lines. First, an on-site LabCorp draw station handles the majority of patient laboratory testing, reducing leakage to outside reference labs and giving patients a single-location care experience. Second, the practice operates an on-site infusion center for administering biologic medications (Remicade-class agents and others) across rheumatic and adjacent immunology indications including Crohn's disease. Third, a sub-brand called GLCOR Research conducts FDA-regulated Phase I-IV clinical trials sponsored by pharmaceutical and biotech companies across multiple indications, providing patients access to investigational therapies and the practice a pharma-funded revenue stream. Patient-facing technology is built on third-party SaaS: a NextGen patient portal for records and scheduling, and InstaMed for online bill payment.

GLCOR's revenue model is straightforward fee-for-service ambulatory care: the practice bills in-network commercial insurance plans and government payors for office visits, infusions, and laboratory services, and explicitly states it does not participate with United Healthcare. Additional revenue accrues from pharmaceutical-sponsored clinical research studies. The practice is physician-owned, with no disclosed venture capital, private equity, or corporate parent. Distribution is single-channel and single-geography — patients are seen at the Lansing office Monday-Friday 7am-4:30pm — making GLCOR a regionally anchored specialty provider with no announced expansion plan.
