The goal? To streamline operations and tackle pressing issues head-on.

This latest news highlights the recent expansion of the County Executive Office. Marin’s also bringing in new talent to lead key departments, from community development to our all-important climate efforts.

It’s a move that’s bound to send ripples through our vibrant communities, from the hills of Tiburon to the shores of Novato.

### A New Era for County Executive Leadership in Marin

Effective leadership really is the bedrock of any thriving community. Marin County just took a big step, revamping its County Executive Office in a move that’s more than just administrative tinkering.

This overhaul, which came out of a 2025 decision, shifts away from the old County Administrator model. Now, Marin’s using a stronger County Executive structure.

The county’s investing in 17 new staff members, costing about $2.5 million a year. With benefits, the total hits $4.1 million.

That’s a hefty price tag, but the goal is clear: give County Executive Derek Johnson more muscle to serve Marin’s diverse communities, from Sausalito to Mill Valley. Will it pay off? Only time will tell, but the intent is definitely there.

This expansion aims to spread the workload more evenly. Four Assistant County Executives are now on board.

With this support, Johnson can focus more on big-picture strategy for the county. The team now includes two new Assistant County Executives, strengthening coverage across vital services.

Key Hires to Drive Marin County Forward

The County Executive’s office has brought in three new faces for pivotal roles. These hires reflect a push for experienced leadership and specialized expertise—pretty important when you’re dealing with the complexities of places like San Rafael and Corte Madera.

Chris Zapata: A Community Development Powerhouse. Chris Zapata comes in with deep experience as a city manager in Sausalito, Anaheim, San Leandro, and National City. As Assistant County Executive, he’ll oversee Community Development, Public Works, Marin County Fire, Parks, Cultural Services, the Free Library, and the agriculture office. He’ll help shape the future of Marin’s towns and keep the natural beauty of West Marin and Inverness intact. His starting salary? $298,293 a year.
Laura Rosas: Driving Public Safety and Legal Services. Laura Rosas brings a background as CEO of Valley Health Plan and federal public health experience. She’ll be in charge of departments like the Sheriff’s Office, District Attorney, Public Defender, Probation, and Child Support Services. While she’s not from law enforcement, her public health and legal chops are a real asset for these critical areas that touch every corner of Marin, from Tiburon to Fairfax. Rosas will also earn $298,293 annually.
Nadia Seeteram: Leading Marin’s Climate Action. Nadia Seeteram steps in as the new Chief Climate Officer. She’s worked with New York’s housing agency and holds advanced degrees in earth systems and environmental science. Her job? Lead Marin’s response to climate change and rising sea levels—a pressing issue from Muir Beach to Bolinas. She’ll head a team of eight, though four spots are still open. Seeteram starts at $194,043 a year.

Strengthening the Core of County Operations

The County Executive’s office is growing fast. Right now, there are 45 employees, and 13 more are on the way.

This push includes hiring a new Budget Director to manage the county’s $902 million budget. That’s a big job, making sure money gets where it’s needed, from busy San Rafael to the quiet farmlands near Point Reyes Station.

Lisa Warhuus will keep leading Health and Human Services and add Assistant County Executive duties to her plate. There’s also a search underway for more support in homeless services—an issue that’s not going away anytime soon in Marin.
