Our founder, Ed Olson, believed in the power of Hawai’i agriculture in sustaining its land and people. The Olson Trust continues the commitment to supporting sustainable agriculture.

Where it Started:
O.K. Farms

O.K. Farms was founded by Edmund Olson and Troy Keolanui, in 2002, with a mission to perpetuate sustainable agriculture in Hawaiʻi.

Edmund Olson and Troy Keolanui partnered to fulfill their vision of a diverse tropical fruit farm that would be a part of their community for generations to come. Twenty years later, O.K. Farms is one of the largest tropical fruit producers in the U.S. and is an incremental stakeholder for food independence in the State of Hawaiʻi.

Located on the rolling hills of Puʻueo Mauka, and home to the Wailuku river that curves around the edges of the land, O.K Farms is truly a magical place. The farm ʻohana has taken initiative to be caretakers of the land and have made efforts to use sustainable practices, improve soil health, and manage invasive species along the river. There are over 1,000 acres that make up the land managed by O.K. Farms and other Olson Trust ventures.

O.K. Farms grows a variety of tropicals; such as lychee, longan, rambutan, citrus, macadamia nuts, coffee, chocolate, heart of palm, and spices, cinnamon, cloves, and nutmeg. Along with O.K. Farms’ day-to-day produce sales, they also created a CSA (Farm Box) which provides other farmers a direct market, as well as feeds local families healthy, fresh, and local produce.

Complete with scenic overlooks and walking paths, O.K. Farms welcomes visitors for farm tours and foodie experiences. O.K. Farms also invites local schools to bring their students to experience a real operating farm and hopefully inspire the next generation of farmers. 

O.K. Farms is now owned by Troy Keolanui and continues to partner with the Olson Trust.

Thanks to Ed Olson, O.K. Farms took abandoned sugar cane land and grew food for their community.

“Keep Hawaiʻi beautiful by using its natural power for good.”
