About our Founder

“Since we are all just passing through… let’s leave these structures in better condition than we found them.
After receiving a BA in philosophy (O.U. 1981), I took to heart Socrates’ advice ‘know a skilled trade.’
An apprenticeship at the Restoration Masonry Co. led me to the realization I’d found my calling. Knowing a niche existed for skilled restoration masons willing to do the job right, I created Cornerstone Restoration. Thankfully many mentors, suppliers, engineers, and old timers helped me along my way. I was lucky enough to have visited with some 80-year-old-plus masons who actually helped build some of Denver’s historic homes. Their recollection of pre-Universal Building Code (UBC) technology was invaluable. Committed to clear communication, logical problem solving, and a desire to do it right, I want to share my knowledge with you.”
