Manager
I have been associated with Cornerstone Construction since its inception back in 1992. I’ve watched my parents start a small business on the kitchen table to renting a small office/warehouse suite all the way to owning, designing and building our own 10,000 SF commercial site with 5 rental suites. At the ripe age of 12 I started to pick up trash and basically do whatever anyone told me to do on the jobsite for half days all summer long. As each summer, Christmas, spring break vacation passed I gradually went from trash boy to lumber hauler to tool gopher (go for this go for that — get it?) to carpenter’s helper, to carpenter, to superintendent, to project manager to Vice President. This has given me a unique perspective to not only experience the work we do but to then estimate it and then manage it. I truly love to build and create things, fix things and help people out.
