W.O. Blackstone & Co., Inc. has a storied history of providing great service to our clients. Mr. Blackstone was a steamfitter by trade who established the company in 1937. Mr. McDowell partnered with Blackstone in 1946 after serving honorably in World War II. McDowell was owner and president from 1970-1982.
Mr. Lewis Caswell came on board in 1958 as a project manager. After Mr. McDowell retired in 1982, Mr. Caswell became the owner. His son Steve worked as a senior project manager and assumed the role of president from 2006 until his untimely death from cancer in 2008. Jeff Griffin came on board in 2013 and now serves as owner and president.
