I have worked in the fabrication/repair and design fields for the past 30 years. I am a Certified Welder, Journeyman Instrument Maker, and Certified Automotive Technician. I hold two college degrees: A.A.S. Machine Trades from Monroe Community College and a B.S. Business Administration from Gardner–Webb University. I enjoy spending time with my family and teaching my two boys all I can. There isn’t much time for hobbies but the one thing I love to do is ride - if you're gonna ride with me be prepared to haul ass and have fun! I thrive on being innovative and being challenged with projects I am told can’t be done. I like to create loud, fast, unique products, and that is exactly what I do!
