Our Board of Directors

Nancy Riggle - Board Co-Chair

Nancy is the Executive Director of Valley Residential Services (VRS), a large nonprofit organization operating in Walla Walla and Columbia Counties. She has worked in housing services in this region since 1978. Nancy’s favorite part of her job at VRS is working with Washington’s Department of Children, Youth, and Families. Her clientele at VRS earns very low incomes and VRS staff earns low incomes. Through her work, Nancy has seen the difference safe secure homes make in people’s lives. She became a Common Roots founding board member after participating in Community Council’s Affordable Housing Study. From the study, Nancy saw that we have an affordable housing crisis, so she wanted to put her money where her mouth was. She has served on several of Community Council’s Affordable Housing Implementation Task Force’s sub-committees in addition to Common Roots’ board of directors. A foster mom for 14 years, Nancy now has 13 adult children who call her “Mom,” and 27 grandchildren.

Wyatt Rolfe - Board Co-Chair

Wyatt was proudly raised in the Walla Walla Valley and has witnessed its dynamic changes over the last several decades. His support of Common Roots is driven by a belief that vibrant and successful communities must have affordable homes. Our housing crisis was recently exemplified in Wyatt’s neighborhood where a 1950 ranch-style home sold for $850,000. Through Common Roots, Wyatt hopes our community can provide affordable homes to the families and individuals that make our region special. In his professional life, Wyatt is a practicing attorney who focuses on estate planning, business law, elder law, and natural resources law.

Riley Clubb - Board Treasurer

Riley is the owner of Harvust, a developer of software for farms and farm workers. He is a former Walla Walla City Council member, and he has spent the last several years working on affordable housing policies and the creation of our region’s first community land trust.

Patricia Divine Wilder

Trish is a semi-retired technical and grant writer/editor. She has lived in Walla Walla most of her life and calls it home. In the past few years, however, Trish’s rent has increased to the point that she isn’t sure she can afford to stay here. When she heard about the plan to start a community land trust (CLT) in our region, she learned that this model could be an exciting solution for herself and others worried about their fast-rising rents. Trish and other board members have participated in multiple training sessions and have been guided through many tough decisions by seasoned CLT consultants. She appreciates that Common Roots Housing Trust will create permanently affordable homes in this region for those with low to moderate incomes and that Common Roots’ homeowners will be members of the organization and have a voice in its governance. Trish notes that there is so much to recommend about community land trusts that she is grateful to have the opportunity to help get our region’s first CLT started.

Mike Rizzitiello

Mike has served as the College Place City Administrator for six years, following two and a half years as the City Administrator in Colfax. He currently chairs the Walla Walla County Council on Housing. Mike’s main concern is the lack of affordable housing here, and what that is going to mean for the community in the long term. He finds it telling that as College Place's top city executive, he couldn’t afford to buy a home in the city until recently. Currently, it is hard to find staff for the city of College Place’s administrative jobs. His fear is that due to the lack of affordable homes here, our region’s main employers may move to the Tri-Cities to find workers there.

She believes everyone deserves a safe, affordable place to call home.

Joy Marie Smith - Board Secretary

Joy is the past president of the Waitsburg Commercial Club Chamber of Commerce. She was one of the early advocates for Community Council’s Affordable Housing Study. In her Commercial Club role, Joy receives many inquiries about housing availability, particularly in relationship to employment or business recruitment. She sees how the lack of affordable homes can negatively impact Waitsburg’s economic growth. In February 2020, Waitsburg had a flood that displaced many of the city’s low-income residents. Working with the Waitsburg Flood Recovery Group, Joy realized that the reason so many people with low incomes were living in flood zones was because the only homes they could afford were there. She is committed to the process of creating permanently affordable homes in her community and throughout our region.
