Siggy Pfendler, LEED AP

Vice President | Improvement & Innovation

Joined Columbia in 2007   

Throughout Siggy’s 20-year career, she has held various roles in the construction industry, from laborer to field engineer, to project manager, to Director of Virtual Construction, to her current role as Vice President. In her current role, Siggy works with all departments to identify, define, and develop best practice workflows and deploy technologies that support and improve operational efficiencies across the company. With dual civil engineering degrees from Stanford University, Siggy’s background extends beyond the traditional means and methods found working at a construction management firm and includes the application of virtual construction software which is becoming increasingly necessary in the construction field as the role of technology matures across the industry. Recognized for her professionalism and open-minded work style, Siggy looks for the red flags in a project and identifies the right people to get in a room together to solve the issues before they become problems in the field. In 2022, Building Women in Construction honored Siggy with the Mentor of the Year Award. The award is presented to an exemplary woman in construction who demonstrates leadership, generosity, innovation and unwavering commitment to their careers, colleagues and industry.

Siggy’s favorite motto is aim so high that you’ll never be bored.  As she adventures out on the open road in her fifth wheel camper with her family pursuing her love of photography, Siggy doesn’t have much time for boredom.
