edicine Horse Ranch is located on a historic 1000-acre fifth generation working cattle and sheep ranch in beautiful coastal Tomales CA. The Marshall brothers journeyed from Ireland and settled the original “Home Ranch” in 1852. Today Gary Thornton and his daughter Marissa, who revitalized the dairy with her flock of sheep and jersey cows, manage the property. The Thornton Ranch is home to 350 Angus Beef Cows, 350 Dorsett Sheep, 111 East Friesian dairy sheep, 10 jersey cows, free range chickens, 2 goats, 4 guardian livestock dogs and 25 horses.

In 2013 Bleating Heart Creamery leased a newly renovated building on the property. The creamery purchases its milk from Marissa’s sheep and boutique jersey cow dairy for it’s handcrafted (and award winning) sheep and cow milk cheeses. The Deeply Rooted garden grows our family produce, including herbs and edible flowers. Guests are invited to enjoy fresh eggs from our resident hens and lush produce when in season. Our ranch guests may also enjoy hiking, and educational farm tours (by appointment), which may include cheese tasting and a visit to the dairy parlor.

We offer public equine -guided education programs for groups and individuals from February- November, (please see our Schedule Page for details.) In 2014, Medicine Horse Ranch became the Northern CA center for Adventures in Awareness™ to best provide access to AIA study opportunities for individuals seeking personal and professional development, which includes field study hours and preparatory modules for certification with the national credentialing board, CBEIP (Certification Board for Equine Interactive Professionals.)


“We spent a lot of time doing nothing.. Watching the clouds go by, picking wild flowers, looking for arrowheads down by the creek, getting our feet wet. We groomed some horses, fed the chickens and fondly recalled the unstructured time of yesteryear; the best times of our lives.” R. Spencer and B. Murphy -Ranch Guestbook 2013
