Kelly Mahaffy

I’m proud to come from a long lineage of industry expertise—over 120 years of collective generational experience in building and construction. I’ve been part of the Medallion team for a total of 12 years, with my most recent chapter beginning in 2017. I first joined Medallion in 1999, starting in the receiving department before working my way into outside sales.

Today, I specialize in providing building solutions to production builders, helping bring new subdivisions to life. With more than 25 years of customer service and sales experience, I’ve built my career on consistency, availability, and dependability—always focused on taking care of the customer. My teammates know me for my accuracy, and my clients know me for my same-day follow-up. I take pride in being a trusted and responsive sales partner.
My approach to sales is rooted in growth and perseverance. I always remind new sales reps to stay positive and remember that success in this industry is a marathon, not a sprint—never hesitate to ask questions and always stay open to new opportunities. My personal mantra, inspired by someone close to me, is simple yet powerful: “Try to do just a little bit better each and every day.” One of my proudest career milestones was taking over a flagship Medallion account from a retiring representative and continuing to serve it with excellence.

Outside of work, I enjoy both playing and watching sports—especially football and basketball. I’m a devoted fan of the Ducks, 49ers, and Trail Blazers. As a proud father to my son, Jordan (25), I treasure time spent with family, especially at backyard barbecues. At home, I share life with my wife, Diana, and our beloved cat, Theo—who I insist is the coolest cat ever known.
