Greg Allen Commercial Sales ManagerHello! I am a Certified Construction Product Representation (CCPR) with the Construction Specifications Institute (CSI) and for almost 25 years, I’ve had the pleasure and privilege of working with homeowners, builders, remodelers, commercial contractors, designers and architects to get the most out of Pella Windows and Doors. Through my years of industry experience, I have learned how to appreciate and meet the diverse needs presented by each customer, their project and members of their project team. Regardless of your project type, budget or role in the project…whether your primary concerns are with aesthetics, installation details, technical specifications or project management, I’m ready to serve you, so let’s get started.
