Business Owner
My nephew, Michael Hartman, and I are the owners of Thos. E. Clark. Prior to taking over the company in 1991, I owned/operated Hartman Plumbing. I have been in the plumbing industry for over 40 years where I worked my way up from apprentice.
Michael has been in the Heating & Air Conditioning industry for over 20 years. Upon his graduation from Salisbury University in 1990, Michael also started as an apprentice.
Both continue to stay abreast of the latest technologies while employing the time tested values that have made Thos. E. Clark a household name in the Washington DC area.
