Marin's New Public Health Officer Working With Mill Valley to Tackle the County's Health Disparities

Health factors such as life expectancy shouldn’t be determined by a zip code in Marin, yet that appears to be the case, says Dr. Matthew Willis, the county's new public health officer.

Marin may be ranked as the healthiest county in California, but it also varies greatly between cities. And Dr. Matthew Willis, the county’s new public health officer, has already started working with the Mill Valley City Council to tackle those health disparities.

“Mill Valley expressed an interest in partnering with Health and Human Services to review that data to help guide their initiatives and priorities,” he said, adding he hopes other Marin municipalities follow suit.

Willis has started working with the city council to address data on leading causes of death, smoking rates, alcohol use and domestic violence rates.

“Marin has consistently had some of the highest health rankings of any county in the state and that’s certainly something to be proud of,” he said in a recent interview in his new San Rafael office in the county's Health and Human Services department.

But the county also has one of the highest degrees of health disparities in the state. Willis said there are significant portions of the Marin population that don’t enjoy the health benefits enjoyed by the majority.

“When I see the life expectancy varying by 17 years in Marin, it’s clear that’s a main issue to address,” he said.

Towns with high expectancies include Kentfield (87), and Larkspur, Tiburon, Belvedere and Mill Valley, which are all at 85. A study recently reported that Marin men have the highest health expectancy in the U.S.

But life expectancy varies greatly between some Marin towns that are just miles apart; parts of San Rafael have the lowest expectancy in the county — 77 — while the nearby Ross has the highest expectancy at the average age of 94.

“Your life expectancy should not be determined by your zip code. But in Marin it appears to be,” Willis said.

The least healthy regions of Marin include portions of West Marin, Marin City, the canal neighborhood in San Rafael and Hamilton in Novato.

“Some people living in certain areas don’t have the opportunity to make healthy choices in everyday life,” he said. This can include a lack of access to green space, safe bicycle paths and health foods options in some areas.

“I see it as my responsibility, as public health officer, to raise the bar for all of Marin’s residents,” he said.

Willis said Marin also has higher than usual rates of exemptions from vaccinations and higher than usual rates of alcohol use and binge drinking, including adolescent drinking.

He said his job — which he started at the beginning of December — largely involves maintaining basic public health responsibilities including:

  • Controlling communicable diseases
  • Disaster preparation
  • Ongoing disease surveillance
  • Maintenance of a high-quality public health laboratory
  • Protection against threats to health from our environment


Even though Willis, 47, returned to Marin a few years ago, he grew up in Marin. It's where he developed a passion for road cycling.

He went to Wade Thomas Elementary and Hidden Valley Middle School in San Anselmo, where his father taught at the San Francisco Theological Seminary. His family moved to New Jersey before he started high school and since he has traveled extensively, first as a professional road racer on the United States National Cycling Team from 1987 to 1990 and then throughout earning his education and during his career that has “straddled public health and clinical medicine,” he said.

Before he went to the medical school he studied medical anthropology and spent a year in Africa volunteering in health clinics. After earning his medical degree from Temple University he earned a Masters in Public Health from Harvard University.

He had been working with the U.S. Centers for Disease Control and Prevention, researching tuberculosis and HIV while spending a lot of time abroad in places including Haiti, Kazakhstan, India and Rwanda.

In Haiti, he spent a month living in a tent on the embassy compound after the 2010 earthquake to build a surveillance system for disease outbreak detection in the tent camps.

He started as an internal medicine provider in Marin Community Clinics in September 2011.

His wife, Heather — a physiatrist in Marin — and their three children, 13-year-old Lily, 9-year-old Thomas and 2-year-old Basil, settled in San Anselmo.

“I came back mainly for quality of life reasons,” Willis said. “We wanted to live in a healthy environment and a place where my wife and I could raise our family surrounded by the values that we’ve come to hold after moving around a lot.”

i'm a perfect example of this. 48, almost 49 years old, with some of the most staggering health results you could possibly imagine (ekg, eeg, blood samples, iq, you name it), yet when i became jobless & homeless 2 years ago, the townspeople of mill valley have happily watched me almost perish out in the streets (& don't seem to have gotten their fill yet) for almost 800 days. the docs used to think i was a triathlete (when all i was doing was sitting around). but, now i'm likely to die of starvation before christmas. not only should your health not be dictated by your zip code; it shouldn't be determined by some of the most incompetent doctors & politicians around. let's hope 'our' new public health officer is successful, for the sake of ALL who deserve better!!!
