Rheumatologist OnCall

What Rheumatologist OnCall does

Rheumatologist OnCall is a private, founder-owned direct-pay telehealth and in-person rheumatology practice established in early 2020 by Dr. Diana Girnita, MD, PhD, FACR, and headquartered at 19712 MacArthur Blvd, Suite 100, Irvine, California. The practice provides rheumatology consultations for patients with autoimmune and inflammatory arthritis conditions — including rheumatoid arthritis, psoriatic arthritis, lupus, gout, ankylosing spondylitis, Sjögren's disease, scleroderma, vasculitis, myositis, and osteoporosis — via telehealth video visits across 20 U.S. states and in-person visits in California. The underlying platform is a secure telehealth system with a patient portal for communication, record sharing, and care management, operating without insurance intermediaries.

The practice monetizes through a layered direct-pay pricing model: one-time diagnostic consultations ($749), non-member follow-ups ($450), second opinion consultations ($797), and recurring memberships ($499/month Personalized Care with 6-month minimum; $299/month OASIS Weight Loss; $165/month Women's Hormone Optimization). Additional revenue comes from peer-to-peer physician consultations ($180-$360), discounted labs/imaging/medication pass-throughs (~80% lab discount), and add-on programs. Customers are individual SMB/consumer patients plus a small set of referring physicians.

The company employs 1-10 staff, including three physicians (Drs. Girnita, Devalla, and Titianu), a practice manager (Darren Joy, RPh), and a patient care coordinator (Pearl Bonsucan). Growth since 2020 has been funded organically without external investment, supported by Dr. Girnita's content ecosystem (15M+ YouTube views, three published books, regular podcast features, and features in NYT, NPR, Medscape) and co-founding of the Direct Specialty Care Alliance in 2021. The practice has launched adjacent product lines (OASIS in 2025, Women's Hormone & Autoimmune Balance Program in 2025) and B2B services (Peer-to-Peer, Second Opinions) to broaden its addressable market.
