Service area

An office in Anthem, and a patch that runs across the Valley.

Medicare plan availability is set county by county, and within a county the differences between neighboring ZIPs are real — Glendale and Peoria alone span several. That is the entire argument for working with somebody who covers this specific patch rather than a call center three states away.

Maricopa County

What people here are actually managing.

Plan comparisons get abstract fast. These are the conditions most likely to be sitting behind a Medicare decision in this county — and each one changes which part of a plan matters.

  • 72.9% Taking blood-pressure medication

    Among adults with high blood pressure. A maintenance prescription is the single most common reason a drug plan that looked cheap in January turns out not to be — formulary tier, not premium, is what decides the cost.

    CDC PLACES, 2023
  • 36.5% High cholesterol

    Another long-term prescription, and another one whose tier can move between plan years without the premium moving at all.

    CDC PLACES, 2023
  • 30.8% High blood pressure

    Common enough here that it is worth checking your specific medications against a plan formulary rather than assuming they are all covered the same way.

    CDC PLACES, 2023
  • 23.5% Arthritis

    Points at orthopedics and rheumatology — specialties where which practice a plan contracts with matters more than what the plan advertises.

    CDC PLACES, 2023
  • 10.6% Diagnosed diabetes

    Brings both a drug plan question and a supplies question, and the two are not always answered by the same part of your coverage.

    CDC PLACES, 2023
  • 5.7% Coronary heart disease

    The clearest case for checking a named cardiologist against a network before enrolling rather than after.

Crude prevalence among adults 18 and over in Maricopa County — not a Medicare-age figure, and the real rate among people over 65 is higher for most of these.

Beyond the map

Not on the list?

I also work Desert Hills and Cave Creek — Desert Hills (85086); Cave Creek (85331). Those do not have a page of their own, which says something about how much I have written rather than about whether I cover them.

The pages above are the communities I work in most, but I am licensed in 18 states. If you are elsewhere in Maricopa County, elsewhere in Arizona, or somewhere else entirely and you have been referred here — call and ask. The worst case is that I point you to somebody better placed, which is a perfectly good outcome.

What I will not do is take on a market I do not know well enough to be useful in. Medicare advice that is not grounded in the specific plans, networks and providers available where you live is not advice; it is a brochure.

Meeting in person

The office is in Anthem, AZ. In-person appointments happen at kitchen tables, libraries, coffee shops and wherever else suits you across the Phoenix metro. Plenty of people would rather do the whole thing by phone or video, and that works equally well — the comparison is the same either way.
