A great firm requires clear vision and strong leadership. Vision gives a company its reason for being, its core values and defines its passions. Leadership provides a company with inspiration and energy, and nurtures its talent.

Senior Principals

Michael E. Hickok, FAIA, founded the company 30 years ago and has guided the firm through its continuous growth and transformation. His extensive design experience and thoughtful management style provides continuity for the firm and is the firm’s foundation.

Yolanda Cole, FAIA, IIDA, LEED AP, merged her company with Hickok’s firm in 2003. She brings over 30 years of base building and interior design experience ranging from large-scale, international mixed-use projects to small specialty projects in the DC region. Her enthusiasm and spark are catalysts for action which drives the firm toward its goals.
