Director of Programs

As a fifth generation Californian, Hannah is both proud to call this state her home and sees so much more potential to improve it for everyone who also calls this beautiful place home. She has spent her career working to translate big ideas into action, via teaching, design, and consulting, and from small organizations to large companies. Build It Green uniquely offers an opportunity to be the home for important, but challenging, conversations on how to address the intersection of so many thorny issues, but at an approachable scale: the places we live and care so much about.


Manager of Network Stewardship

Chloe feels most at home when she’s near the ocean. She loves the diversity of cultures, architecture, and climate zones that California has to offer and cares deeply about rising to the challenges of our time to protect and evolve how we live for a brighter future for all. She has been committed to social entrepreneurship, sustainability, and empowering people through professional development throughout her career.  She has traveled all over California to meet and train contractors on energy efficiency programs, supported operations for a  woman-led solar entrepreneur network in Nepal, and delivered national pop-up professional workshops for trades professionals to pursue green jobs. She graduated with an MBA from William and Mary with a focus on entrepreneurship and data analytics.


Communications Director

Sabrina is a purpose-driven storyteller and has led media, marketing, and communications strategies for local and national organizations across a range of environmental and social justice issues to drive awareness, narrative change, and brand affinity.

As a fifth-generation Californian and first-generation-born Chinese American, Sabrina considers the Golden State her home. She is the daughter and granddaughter of immigrant farmers. Having grown up alongside migrant workers, she cultivated a deep interest in food as cultural identity, organic agriculture, labor and immigrant rights, affordable housing, and environmental health and justice issues. Build It Green offers a unique opportunity to merge her interests and contribute to housing solutions that will address climate and equity issues.


Operations Manager

A lifelong native of California, Kurt has a strong fondness for California’s abundant outdoor activities and its distinguished weather makes it hard for him to imagine living anywhere else. Kurt holds a bachelor’s in Earth Systems Science and a hybrid-masters degree in Environmental Science and Management. Before joining Build It Green, he contributed to the development of Climate Action Plans for the cities of Gilroy, El Cerrito and Piedmont to help meet State GHG emission-reduction goals. He is extremely excited to expand on his work with Build It Green as it evolves from going beyond sustainable aspects of a building to further emphasizing societal health and well-being.

Program Associate

Jenny values communication and relationships, and believes that one of the best ways to tackle complex problems is by building strong community connections. She holds a master’s degree in Environmental Science and Management from the Bren School at UC Santa Barbara, as well as a bachelor’s degree in Integrative Biology from UC Berkeley. Most recently, she worked on advancing sustainability efforts at college campuses. Now, she is excited to address intersectional issues of sustainability, affordability, and equity in housing as a member of the Build It Green team.


Executive Director

Two of Jeremy’s most beloved things are great cities and awe-inspiring natural landscapes, and, living in the Bay Area over the past 20+ years, he has had no shortage of these.  A day can literally start with a hike in redwoods, followed by lunch at a sidewalk café serving local specialties, and end with an afternoon at a world class museum. What could be better than that?

Jeremy was born and raised in the suburbs of Salt Lake City, Utah by a father who owned a company that built HVAC ductwork, and a mother who was a proud environmentalist. His upbringing and lifelong interest in the intersection between the built and natural environments—and their relationships to social equity, community vitality, and, to say it simply, happiness—led him to spend 10 years as CEO of Greenbelt Alliance, the Bay Area’s leading land conservation and land use advocacy NGO.

Build It Green was a natural step for Jeremy. As it becomes an organization that doesn’t accept that there have to be trade offs between housing affordability, climate protection and other environmental issues, and social equity and justice, he looks forward to bridging and serving all of the different constituencies in the housing ecosystem to fundamentally change what this state will be like for decades to come and, in doing so, can make California a model for the nation.

In his free time, Jeremy can usually be found on a soccer field or listening to loud music ranging through all genres of rock (punk, Celtic, classic, grunge).
