Is Dr. Trager accepting new patients?

Yes — Dr. Trager is currently accepting new patients through the GentsMed network. New-patient consultations are typically scheduled within 1–2 weeks; same-week appointments are sometimes available depending on the clinic's current load.

Does Dr. Trager offer telehealth visits?

Initial consultations with Dr. Trager are conducted in person so a thorough intake, exam, and any required labs can be completed. Follow-up visits for established patients can typically be conducted via telehealth where state regulations allow, with the exception of controlled-substance prescribing, which generally requires periodic in-person visits per federal law.

What should I expect at my first visit with Jonathan?

Your first visit is a thorough intake and clinical conversation covering your symptoms, goals, medical history, and any prior workup. Depending on the treatment you're considering, Jonathan may order baseline lab work or arrange a brief physical exam at that visit. You'll leave with a clear next step — not a same-day prescription pad. Expect 30–45 minutes.

Does Dr. Trager accept insurance?

Dr. Trager runs a cash-pay practice for Dermatology services. HSA and FSA cards are accepted at the time of service. Some labs and consultations may be eligible for insurance reimbursement depending on your plan and the indication — the clinic can provide a superbill on request.

Don't go to a chain clinic. Go to a real physician like Jonathan Trager, MD. The difference in care is night and day — labs, follow-ups, dose adjustments based on actual data.

Solid provider, good bedside manner, and clearly cares about getting the protocol right. Appointment availability could be better but the care quality makes up for it.

I'd been to my PCP for years about the same issues and getting nowhere. One visit to Upsize New York and I had labs, a diagnosis, and a plan. Six months in and the difference is real.
