John CoghlanOwner & Designer

After graduating with a degree in International Business, John spent eight years learning Spanish and pursuing social-focused businesses in areas dealing with systemic poverty. That journey led him to studying permaculture at the Bullock’s Homestead on Orcas Island with his wife in 2011.  In the summer of 2012 John completed an intensive course in edible forest gardening with Dave Jacke.

To continue his education in natural systems and wildlife processes, John moved to Vashon Island, where he puts a practical application to his studies in edible forest gardening, mushroom cultivation and integrated holistic landscape design. John’s main concern is designing and building gardens that people can use for food, pleasure and medicine. John enjoys soccer and bicycling.  He and his wife have two young daughters, who specialize in eating berries and digging holes in the garden.

Special expertise: Permaculture, Food Forests, and Edible landscape design.  Plant education. Spanish.

Julia’s first gardening experience was removing asphalt in her family’s backyard with other 10 year olds using croquet mallets found left out for trash on the street. She loved planting beans, carrots and tomatoes and watching them grow! Her first landscaping job was on the grounds crew of the Scott Arboretum on the campus of Swarthmore College in Pennsylvania. After studying tropical ecology in Costa Rica, she wrote her undergraduate thesis on the ways in which indigenous methods of organic agriculture are more efficient than petroleum-based, colonizing/settler methods. With an MBA in sustainable business from Pinchot/Presidio, Julia is thrilled to bring all these passions together for HGO!
