1948 – Jack Pitts, and his son-in-law Stan Raplee, turned their love of big beautiful trees into a business and Washington Tree was born.

1950 – More caterpillars than you’ve ever seen hit the Seattle area! Stan and Jack figure out a way to get rid of them, and the pest control side of the business takes off.

1963 – Jack and Stan expand again, this time into lawn care.

1967 – Jack retires but the business continues to thrive under Stan’s leadership.

1974 – Randy Mock, a 23-year-old friend of the family, joins the Washington Tree & Lawn Care team as a helper on a spray truck … and never leaves!

1980– Randy takes over the Lawn & Weed division.

1986 – Ed co-founds Washington Friends of Farms & Forests, to encourage and build dialogue and unity between pesticide companies and environmental advocates in Washington State.

1997 – Ed takes the helm from Stan, becoming president and CEO.
