Illinois Dermatology Institute

What Illinois Dermatology Institute does

Illinois Dermatology Institute (IDI) is a physician-owned dermatology group practice founded in 1989 and headquartered in Illinois, operating 15 clinic locations across the Chicago metro (Chicago Lakeview, Chicago Loop, Hinsdale, La Grange, Northbrook, Oak Park, Palos Heights, Park Ridge, Schaumburg, Skokie), broader Northern Illinois, and Northwest Indiana (Chesterton, Crown Point, Michigan City, Munster, Portage). The practice delivers a fully integrated dermatology platform across three service pillars: medical dermatology (acne, eczema, psoriasis, rosacea, hair and nail disorders, skin infections), cosmetic and aesthetic dermatology (Botox, Dysport, Juvederm, Restylane, Radiesse, Sculptra, Morpheus8, Thermage, fractional CO2, Laser Genesis, IPL, PDT, microdermabrasion, sclerotherapy, tumescent liposuction), and surgical dermatology (Mohs micrographic surgery, excision and repair, subcision, Superficial Radiation Therapy). It also operates an on-site pathology laboratory and a walk-in immediate-care service.

Beyond clinical services, IDI runs an active in-house clinical research program (DeNova Research) led by Dr. G. Michael Lewitt, conducting trials across hidradenitis suppurativa, psoriasis, atopic dermatitis, vitiligo, and prurigo nodularis, with sub-investigator Andrew Mastro, PA-C, and dedicated research coordinators. The business model is a multi-location fee-for-service dermatology practice with two revenue streams: patient services revenue (medical, cosmetic, and surgical procedures billed to patients and insurers, including higher-margin self-pay cosmetic work) and clinical trial compensation from pharmaceutical sponsors. Patient acquisition is sales-led and direct, supported by a website with a ModMed-based patient portal, a multi-language interface (Chinese, Hindi, Korean, Polish, Russian, Spanish, Urdu via Google Translate), special offers, and clinical study recruitment. The practice is privately held by physician partners, with no disclosed private equity, venture capital, or parent-company ownership.
