As the CEO of The Gathering Inn, Keith comes to his position with a history of service to some of the most disadvantaged populations across the United States. Keith traces his affinity for helping those that are less fortunate to an experience he had when he was just 14 years old. At that age, Keith visited the historic campus of Boys Town, Nebraska and learned firsthand that not every child grew up to live in a two-parent household with middle income means. It was during this time that Keith learned to appreciate what he had and felt compelled to have a career helping those who were less fortunate. Keith attended Wayne State College in Wayne, Nebraska and received a dual major in both business economics and sociology. After a brief stint in Denver, Colorado as a manager of a Bennigan’s restaurant, Keith returned to Omaha, Nebraska and began working at Boys Town as a youth care worker in one of the residential programs. Over the next five years, Keith worked in this position while putting himself through graduate school at the University of Nebraska- Lincoln with a major in child and adolescent development. Over the next 20 years, Keith moved to various Boys Town locations across the country at the request of the organization, including New Orleans, Louisiana; Tallahassee, Florida; West Palm Beach, Florida; and LA/Orange County, California. With each move Keith’s responsibilities grew; in both West Palm Beach and LA/Orange County, Keith was the President/Executive Director. Due to his leadership, all of the various locations saw an increase in program and budgets by at least 200%. Keith was recognized internally within the Boys Town organization as a skilled change agent that rejuvenated the mission, vision, and values of the Boys Town locations in which he served. After his 20 year career at Boys Town, Keith was recruited to Stanford Home for Children and presided over an organization-wide strategic planning process which led to a complete rebranding of the agency and renaming of it to Stanford Youth Solutions. Keith left Stanford Youth Solutions after successfully transforming that agency over a period of five years and opened his own consulting business. Keith’s skills in organizational cultural transformation have helped numerous clients including both for-profit and non-profit businesses such as Brooklawn and Bellewood youth agencies located in the state of Kentucky, Irvine Public Schools, government agencies in California, as well as AH Wines located in Lodi, California. Keith came to The Gathering Inn with a desire to build upon the good work that had been done over the years and position the agency for the next phase of growth. Keith values community partnerships and collaboration and is working to strengthen The Gathering Inn’s relationships in the community. Since 2015, under Keith leadership, The Gathering Inn’s budget has grown over 270% and the number of clients served per day has increased over 235% during the same time period. On any given night, 188 homeless clients are served in what now is four separate programs serving the homeless in Placer County. The Gathering Inn is now the largest homeless services program in Placer County.

Keith has served on numerous nonprofit boards in the throughout the United States, including both local and statewide organizations that served children in the educational and foster care settings as well as being a Board member of the Homeless Resource Council of the Sierra’s serving the homeless here in Placer/Nevada Counties. Keith has six children and is currently married to the love of his life, Jennifer, who is the CEO of Make-A-Wish Northeastern California Northern Nevada.
