Marin County Supervisor Steve Kinsey says his job is less a job than a “lifestyle.” He regularly works more than 50 hours a week between office activities, community events and meetings; he and his colleagues sit on multiple regional, countywide and nonprofit boards—for Supervisor Kinsey, those include the Metropolitan Transportation Commission, the Marin Agricultural Land Trust, the Marin County Housing Authority Commission and Marin General Hospital’s advisory board, to name a few. He spends his evenings attending community fundraisers, meetings or public hearings. “I keep my running shoes with me so that if an hour long run is possible, I can take it,” he said. “My trail running is where I am able to do most of my original thinking.” Yet both candidates for District 4 supervisor, vying for the seat he will vacate at the end of the year, are business owners who, if elected, will have to prioritize their responsibilities come January. Olema resident Dennis Rodoni has been running his contracting business for the last 35 years; Dominic Grossi is a fourth-generation dairyman west of Novato. Mr. Rodoni said if he wins the election, he will shift ownership of the business over to his wife, Judy, and daughter Megan, who he said has been doing bookwork for him for the last 10 years and has begun to take over control of the company in the last year. “I’ve been backing out slowly,” he said. If the election favors Mr. Grossi, his plan is to remain on as a partner with his parents in the dairy. He would work on the ranch sparingly, as time permits. “Early mornings and computer work [for the dairy] in the evenings is what I foresee myself doing,” he said. Mr. Grossi said the dairy is in the process of becoming certified organic, which will reduce his herd by about half; that change will allow one of his employees to stay on full time and assume many of his own responsibilities.
