John DeSilvia is a tough-as-nails Brooklyn native and a former union carpenter. A licensed contractor, “Johnny D” earned a degree from the Pratt Engineering School. After graduation he learned the ropes with two of the world’s leading construction firms, then took the plunge and opened his own company, Brooklyn's Design Tech, for which he’s currently working on a high-end, two family home in Brooklyn. On DIY Network's new Run My Renovation series, John leads renovations for 13 different homeowners whose design fate is left up to DIYNetwork.com users. In Under Construction he demolishes, builds, renovates and refurbishes projects all over the Big Apple. And watch him show real homeowners how to cut up to $10,000 from their renovation and remodeling projects on DIY Network's series 10 Grand in Your Hand. In 2010, John also serves as the host of television’s first-ever interactive home building series, Blog Cabin.
