Our Story
MMP Sheet Metal was founded by Frank Varanelli, whose career began as an experimental sheet metal mechanic working on critical aerospace programs, including the NASA Apollo and Saturn projects, the B-1 bomber, and the Boeing 747. This hands-on experience in high-performance, precision-driven environments established the foundation for the company’s standards of excellence.
Today, that legacy continues as the next generation carries forward the same dedication to craftsmanship, quality, and customer service. The knowledge, discipline, and attention to detail instilled by our founder have been passed down to Mike Varanelli and remain at the core of everything we do.
