I am a water scientist who has dedicated my career to bringing safe and clean drinking water to the developing world. Marin faces its own water challenges. I am running for water board to use my expertise to ensure our water system is resilient to drought and climate change, responsive to Marin residents and has a strategic plan moving forward.



•    Rely on science, not politics, to establish a safe, affordable, and sustainable water supply for Marin.
•    Manage our watershed to reduce wildfire risks.
•    Collaborate with scientists, policy experts, and the public to ensure decision-making is transparent.
•    Improve public education and access to the watershed and its surrounding natural resources.



To win this election, we need to get our positive message to voter’s mailboxes and inboxes, on the screens they watch, over their phones and at their doors.

This effort is only possible with your financial support.

Please consider contributing today.

Ranjiv and Kristina moved to San Anselmo in 2008 where they enjoy biking, hiking, and running on the trails that make Marin such a special place to live. Kristina is a Director and Senior Scientist at the Exploratorium. Their daughter, Zara, a fifth grader at Brookside Elementary School in San Anselmo, is a passionate soccer player with the Ross Valley Breakers Football Club and a fearless mountain biker.
