About our Instructors & Staff
Healing Tide, is functional medicine based community healthcare.
We envision a world where access to healthy food, herbal medicine, education, nature, and support ushers transformation internally, community-wide and beyond.
Healing Tide is a 501(c)(3) non-profit that seeks to live in harmony with the Earth,
while we explore traveling from a sustainable lens.
Currently, we are focused on producing seaweed wild-tending tours in Northern California.
Healing Tide acknowledges that we live in the Huchiun, Lisjan Ohlone, Carquin, and Awaswas territories. Healing Tide believes in rematriation of the Land, reparations, and restoration. It is important to acknowledge the lands we live on, travel across, and visit. Healing Tide is in continued communication with local tribes. We donate seaweeds to tribal Elders, volunteer on the Ramaytush Muchia Te' Indigenous Land Trust Farm, and donate 10% of the proceeds of Healing Tide towards these Tribal collaborations. If you are a tribal member and would like to collaborate, please let us know.
