About our company & the people who complete it.


Cornerstone Services, Inc. was initially founded in July 1998 to support small-to-medium sized non-profit organizations who felt using a third-party vendor was beyond their fiscal grasp. Starting small allowed us to remain humble while becoming an authority in USPS postal regulations. True to our roots today, we still do not turn down any work due to low mailing volume or data size, and we still pick up materials, free of charge, within our regional vicinity.

James Davila James Davila

Systems Administrator

James keeps watch over Cornerstone's flock of servers. He is adept at using virtualization to simplify this task, as well as automation to give himself thousands of eyes and ears on the machines he oversees; "Security" is his watchword. Although raised on Long Island, James honors his birthplace by remaining a dedicated New Jersey Devils fan, and he proudly displays his Spanish heritage with his perfectly accented Castillan and love of fine coffee. Indeed, James could be described as a complex machine that transmutes caffeine into elegant code in a variety of languages.

Andrew Kozak Andrew Kozak

Special Projects

Andrew was born and raised at the Jersey Shore although his fair skin wouldn't hint at it. He is conversant in all modern technologies, has been programming since the third grade, remembers life before HTML had a version number, and prefers the hose for chasing kids off his lawn. He enjoys writing and is an outspoken advocate of English spacing, Oxford commas, and Roman quotes. Andrew also enjoys traveling, training, and studying a variety of subjects. When not in front of a screen or under a bar, he practices calligraphy, judges costuming competitions, and continues to work on trying to speak as many languages as he feels he should.

Doug Griffin Doug Griffin

Customer Service

Overseeing much of Cornerstone's progression as an organization, Doug is coincidentally something of a father figure here. He supervised the construction of this very website, and is working on a solo project to get Exact JobBoss to help the company progress.
