Leadership Team

Shawn Puster
Co President – Owner
My focus is to build and maintain excellent relationships between the manufacturers we represent and the customers we serve. I achieve this by being in the field daily to understand what our customer’s needs and expectations are so we can provide solid insight to our manufacturers. After 30 years in the building materials arena, I keep an open mind in the present and look to the future to help make the adjustments needed to allow our company to be successful.

Bruce Landenberger

Focusing on Finance and Operations throughout my career in the Building Materials and Wholesale Packaging industries has given me a unique perspective when it comes to bridging the gap between manufacturers and their customers. Finding cost-effective solutions has always been a driving force for me in helping companies succeed.

Larry Miller
Territory Manager- OH, WV & Western PA
I grew up working with my dad in our family’s garage door business. Even before I finished school, I was learning to install doors. I spent the next 40+ years learning every aspect of the industry from installation, service, repair, and sales. All these skills helped me when I purchased the company and continued growing what my dad started. I later sold the business, but continued working there in sales, which is the role I love the most. In my career, I have built and maintained solid relationships with customers and suppliers alike, some beginning 40 years ago.
My wife Carol and I have two adult children, one dog, two grandchildren and one grand-puppy. When I’m not spending time with them, I enjoy hunting, fishing and playing softball.

Rebecca Popky
Territory Manager - Tennessee
My love for sales and people started when I began waiting tables to support myself through college. It of course grew from there. I have two years as an outside sales representation experience in the building industry covering the northeast states before starting my almost 5-year career as a director of sales for a heating manufacturer in Tennessee. Throughout my career I have earned the trust of several regional and national accounts and maintained strong customer relationships that generate repeat business.
For the past almost 5 years I have lived and currently reside in Tennessee after relocating from Northeast Pennsylvania. I have such a fondness of Tennessee and its people who welcomed me with open arms. In my free time I enjoy, cooking, kayaking, my mini dachshund Maisel, and visiting my young nephew.
