Board of Directors
Monthly board meetings are held the 2nd Monday of each month at noon.
Katy McLaughlin President,
Outreach Committee
I am both personally and professionally, as a resident who enjoys the opportunities provided by living close to the downtown core and as an organization that benefits from being included in the Historic Downtown area. Having a strong, connected community core is important to me as part of my family's well-being, and having options and high quality of living was a big reason we moved to Prosser. As the librarian I've worked regularly with HDP over the years on programs that benefit both organizations, and I would like to continue to bring more people to the downtown including the library.Â

John Breeze
Outreach Committee Chair
I was born in Coeur d'Alene, ID, and moved to Prosser in 1972 on my birthday. I turned 8 years old in Prosser and have loved it ever since. I started my life here in a house built in 1902, which began my love for historical architecture. After Prosser High School class of 82, I joined the Army. I served my country for 8 years, traveling the World. I was fortunate to get stationed in South Korea, and the building that I still remember fondly is a 6th-century temple. It was amazing how it was put together with ¾ in wooden pegs. I found my way back to Prosser after leaving the Army. Currently, I am the kitchen manager at the Prosser Senior Center, Junior Vice Commander for the Prosser VFW, and Volunteer for the Lower Valley Honor Guard. I enjoy meeting new people and volunteering where needed. I have always been a student of history. I love to be on the board to continue learning about my community’s history.
