Leo Chapman, Farm Institute Land Match Manager

Leo moved to Nevada City from Sacramento with his wife and daughter in 1986.  His idea was to start a family farm and restaurant.  After 4 years he decided that the timing wasn’t right and went into general contracting.  In the year 2000, the timing was right to give farming another try. Volunteering with BriarPatch in the produce department gave Leo a look at organic vegetables. He decided we could grow better food locally.   He worked for Mountain Bounty farm as an orchard manager for 4 years, and then he worked for Riverhill Farm as a farm hand for several seasons. 

Leo’s passion for farming grew and in 2006 he started farming Blue Bird Farm. He wanted his grandchildren to know where their food came from.  Farming changed Leo’s life connecting him with seasonally delicious food.  The farming life style change quickly aligned Leo with his belief system.  In 2007 he co- founded Living Lands Agrarian Network, and educational non-profit to train the next generation of farmers.  The next 7 years he helped create 9 farm sites within the Nevada City area. He worked with local organizers and farmers to establish the Nevada City Farmers Market.   He started the farm to school visits and school to farm visits with the local elementary schools. He created a formal internship program for Living Lands, and ran a successful journeyman program with 3 participants.  In 2013 when Living Lands merged with Live Healthy Nevada County, to become Sierra Harvest, Leo established and ran the Sierra Gardens program, building backyard gardens in the community. Becoming 2017 Volunteer of The Year for Sierra Harvest was a highlight for Leo.  He has made giving back to the community a big part of his life. Currently he is running the Land Match program for Sierra Harvest matching land owners with farmers wanting to farm.
