What is Lunch and Learn? PKSB Architects utilizes each and every Thursday where the entire staff has lunch together. The ordering of the meal and the scheduling of the learning event is provided with great efficiency by Nancy Cusack here at PKSB. Each and every Thursday we come together face to face to discuss projects, news, learn about new products, systems, ways to build, building code compliance and design innovations. No matter what is or is not on the agenda, the PKSB Lunch and Learn is a moment for us to share knowledge related to the projects we work on, the city we live in and the profession we engage in.
