The Achadinha Cheese Company is a family operated ranch lead by Jim and Donna Pacheco along with their four children William, Daniel, Elizabeth and David. This family tradition began 3 generations ago in Achadinha, Portugal and Vallejo, California with both of Jim's grandfathers milking cows. In 1955 Jim's parents branched out on their own and eventually in 1969 they ended up in Petaluma where the Pachecos are currently milking cows and goats to make their own Farmstead cheeses and sell at various Farmers' Markets around the Bay.
