Mark Doucette

Originally from Halifax, Nova Scotia, Mark has had extensive experience working with plants in diverse regions. He worked in Nova Scotia, Ontario, Alberta, and British Columbia in Silviculture, planting just shy of 1,000,000 seedling trees in his 5 year forestry career. He later moved to Victoria, BC, where he worked with local gardeners. It was during this time that Mark developed his interest in farming and a garden design method known as Permaculture. His exposure to Permaculture and the urban-farming/gardening community is what rooted his passion to pursue a career in Horticulture.

In 2014 Mark immigrated to Washington State where he married his wife, Hannah. From 2015-2018 Mark had the honor of working with the incredibly knowledgeable and hardworking staff of the Bloedel Reserve located on Bainbridge Island. The Bloedel Reserve is a nationally recognized botanical garden and forest preserve, and this is where Mark received his CPH certification.

Mark currently resides in Suquamish with his Wife, Son, Dog, Cat, and Flock of Chickens. You can usually find him digging in the garden, or wandering the woods hunting for wild edibles, medicinal plants, and mushrooms.


Hannah Blankenship

Hannah has spent the majority of her life in Suquamish, Washington. She was lucky to grow up playing in the woods and splashing in the Puget Sound. After several years of traveling and working on various organic farms and homesteads through WWOOF, she settled down in her hometown to start a life with Mark.

Hannah has always had a deep interest in the natural world, and has finally found a way to combine her love of nature with a passion for design, to form the other half of Wassail.

She cares deeply about traditional methods of food preparation and preservation, herbal medicine, swimming and sailing on the salty waves, foraging, playing harp, and hanging with her absurdly cute family, and did we mention food?!
