San Antonio's independent Medicare agent — by phone, by Zoom, on your schedule.
Mark Steinberg has been a licensed insurance agent for more than two decades. In that time, he's watched a lot of San Antonio seniors sign up for the wrong Medicare plan — not because they were careless, but because nobody walked them through it. Medicare has too many moving parts to figure out alone, and most agents are too busy chasing the next sale to stick around after enrollment.
That's why Texas Hill Country Medicare works differently. As an independent Medicare agent, Mark isn't tied to any one insurance company. He works for you. That means he compares Medicare Advantage, Medicare Supplement, and Part D plans across all the major carriers and gives you honest advice about what fits your situation — even when the answer is "stay with the plan you already have."
Mark is based in San Antonio at 17803 La Cantera Terrace, San Antonio, TX 78256, and is licensed across 16 states. Most of his clients are right here in the Texas Hill Country — San Antonio, Stone Oak, Boerne, Bulverde, Spring Branch, Fair Oaks Ranch, New Braunfels, and Fredericksburg. Everything is done by phone or video, so you never have to leave your house, fight traffic on 281 or 1604, or sit at a kitchen table with a salesperson.
Why work with an independent agent?
Insurance carriers employ two kinds of agents: captive (work for one company, can only sell that company's plans) and independent (contracted with many carriers, can compare across the market). Mark is independent. Here's what that means in practice:
- No bias toward any single carrier. If Humana isn't the best fit, you won't get sold a Humana plan.
- Side-by-side comparisons. Mark runs your specific medications, doctors, and ZIP code against every plan he represents.
- You don't pay extra. Independent agents are paid by the insurance carrier on enrollment — the commission is the same whether you go through Mark or directly through the carrier.
- Year-round support. Mark reviews every client's plan during the Annual Enrollment Period (October 15 – December 7) automatically. No surprises.

2. Side-by-side plan comparison
Mark runs your specifics against every plan available in your ZIP code and brings you the two or three that actually fit.
3. No pressure to enroll

4. Year-round service
Annual plan reviews, claims help, network questions, prescription changes. You get an agent, not a transaction.
