MP-Squared (MP2) is marking a significant milestone this year as we celebrate 20 years of client-focused structural engineering.
Founded in 2005 by Mark Puccio (CEO) and Melissa Peyton (CFO), MP2 currently employs 15 full-time employees in Madison and one in the Fox Valley area. In addition to being a 50% woman-founded business, we employ one of the highest rates of female engineers to total engineers in the area!

Melissa Peyton and Mark Puccio, founders of MP-Squared Structural Engineers.
Since our founding, MP2 has built a thriving business by prioritizing relationships with clients, partners and employees.
Our CEO Mark Puccio sums it up best: “We treat each client as if they were our only client. We’re practicing structural engineering, but this is still very much a service industry.
“We had both worked for large companies where leaders pushed fiscal budget ahead of doing great work. We wanted the freedom to let budget take a backseat to quality and excellence.”
We’re proud to say most of our clients are repeat customers!

They are trustworthy, ethical, professional with very high moral values. Our project success is directly related to having MP2 involved in the project.
