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.
