Kathryn “Katie” McCamant brings the depth and diversity of her 30 + years of experience as an architect, developer, and cohousing resident.
She is a licensed architect and coauthor of the authoritative book, Cohousing: A Contemporary Approach to Housing Ourselves which introduced cohousing to the English-speaking world. Katie co-founded McCamant & Durrett Architects/Cohousing Company with Charles Durrett in 1987. In 2006, she and Jim Leach (Wonderland Hill Development) co-founded CoHousing Partners, a development company that partnered with cohousing groups. Today, she is the sole owner CoHousing Solutions, a development consulting firm that works with cohousing groups and developers across the US and Canada.
Katie has designed and developed dozens of cohousing communities in the United States and Canada. After 12 years living in and raising her daughter at Doyle Street Cohousing in Emeryville, she now lives at Nevada City Cohousing in the Sierra Foothills.

For more than 30 years, Brad has lived in, managed, designed, and built communities rooted in social connection and ecological awareness. His architectural approach centers on creating spaces that inspire and empower—an ethos shaped in part by his formative work with sustainable design pioneer Paolo Soleri at Arcosanti in the 1990s.
As founder and principal of Emeryville-based Gunkel Architecture, Brad leads a team dedicated to designing dynamic, human-centered environments across residential, educational, mixed-use, and affordable housing projects. Guided by the belief that housing is a human right, the firm brings deep experience, thoughtful collaboration, and clear communication to every stage of the design process.
Outside of work, Brad enjoys adventuring with his wife, hiking and backpacking, exploring astronomy, and expressing creativity through poetry and oil painting.

Amber is a natural communicator and facilitator with almost 20 years of experience. As Project Manager / Project Architect for Gunkel Architecture, Amber guides clients through the process of creating homes and spaces for themselves and others. While growing up, she was often involved in helping her civil engineer dad take on a variety of home improvement projects. She has a great appreciation for design, and her love of the multitude of design styles makes it easy for her to support other people in expressing their visions.
Amber enjoys playing the accordion, singing, and writing music. She has recorded albums, and at one point took a three-year break from architecture to be a touring musician.

Christina Marshall brings more than 20 years of experience in sales, marketing, and community development to Coastside Cohousing. As founder of Coho Collab, she partners with forming and developing cohousing groups across North America to strengthen membership growth, refine messaging, and create outreach strategies that attract and engage future neighbors.
Christina’s approach combines hands-on marketing execution with a deep understanding of how communities form and flourish—from strategic branding and website development to event promotion and media outreach.
She’s passionate about helping Coastside Cohousing share its story widely and build the connections that will bring its vision to life.
