The Pendleton Historic Foundation was founded in 1960 to ensure the preservation of the historic house at Woodburn. While the funds were being raised to restore the Woodburn house, the Mead Paper Company donated Ashtabula and an additional 10 acres of land to the Foundation, similarly ensuring its preservation for future generations.

As a result of these efforts, the Pendleton Historic Foundation now owns and operates two of the largest Upcountry plantation homes as historical museums for the enjoyment and educational purposes of visitors of all ages.

Educational Programs: A major focus is providing insightfull programs for school groups along with hands-on demonstrations. Each year, the Foundation sponsors a number of educational programs at each house including two historic reenactments as well as living history tours. The Foundation hosts 15-25 special school tours each year.

Historic Pendleton:This is a new subsidiary made up of local homeowners of houses over 50 years. This organization provides preservation education and support through a historic house regristry, speakers program and bi-monthly meetings.

Fundraising: The Foundation hosts an annual fundraising gala at Woodburn benefiting the Foundation's Preservation Endowment. When fully funded, this endowment will provide operating funds for annual maintenance and further preservation projects.
