About Winter

Winter is a growing leader in Bay Area community outreach and stakeholder engagement striving for sustainable and equitable transportation for all. Our team brings 45 years of combined experience engaging diverse stakeholders—from city and transit agency staff and elected officials to community leaders, business representatives, and folks from the general public. We specialize in reaching voices historically left out of the planning process through our network of CBO partnerships and community relationships forged over two decades.


Our team uses extensive in person and digital outreach, ranging from small focus groups to large panel discussions to public meetings incorporating the latest technologies in real-time audience polling and engagement software. We pride ourselves on making complex information palatable to the public and enjoyable to engage in order to maximize the amount of valuable feedback we receive from our participants.

As a boutique firm, we benefit from the infrastructure and personnel to tackle complicated endeavors, yet we’re also small enough to deliver the agile personal touch every project deserves. We bid only on projects our team genuinely believes will improve the communities in which we live and work.

Transparency & authenticity: open and honest about our process

Inclusivity: of people’s ideas, cultures, customs, & communication styles

Compassion & collaboration: patient, kind and moving at the speed of trust

Accountability: to community, to clients, and for the high quality of our work

Corinne Headshot.png

Corinne Winter 
President & CEO

Born and raised in the Bay Area, Corinne brings 20 years of professional experience supporting sustainable and equitable change in the transportation industry. In her decade as executive director of the Silicon Valley Bicycle Coalition and board chair of Transform, she helped expand membership bases, raised community awareness of the importance of sustainable transportation, and advocated for bike-able and walkable communities for all. She engaged diverse stakeholders including city and transit agency staff, elected officials, developers, community leaders, and business leaders. Corinne then founded Winter in 2015 to help ensure local community voices and concerns–especially those of historically underrepresented communities–were being heard by the agencies drafting and planning future transportation policy and projects. Corinne’s approach presupposes that continued progress toward a more sustainable transportation landscape cannot be decoupled from racial and social equity concerns.
