Kenny holds a B.S. in Biology and a minor in chemistry. With more than a decade of experience evaluating tools, his analytical and scientific mindset helps him design repeatable testing methods for Pro Tool Reviews’ head-to-head testing and offers highly objective comparisons in his reviews.

Kenny’s life around power tools started early. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago.

At home, Kenny’s dad made the family budget stretch further by doing many DIY repairs around the house. From his dad, he was able to learn irrigation, landscaping, car maintenance, basic electrical, and more. He even rewired their bass boat for fun one weekend as a young teenager.
