Barbara Mullenex


Principal | Executive Director

"I am always focused on how people experience and explore the built environment--people who are in a space every day, people who visit, and people in the surrounding community. I also strive to enhance the experience of designers so they may learn, become better contributors to our communities, and move forward in their careers."

For over 30 years, Barbara has focused her career on people. As a Managing Principal of the Washington, DC studio, she actively supports and strengthens Perkins Eastman’s mission and values through active participation with clients, support organizations, and philanthropic associations. With expertise in organizational strategy, talent development, and outcome-based management, Barbara makes unique contributions to projects across all practice areas from hospitality and residential to large scale mixed-use and workplace. Barbara maintains focus on producing creative and innovative solutions for her clients by building teams that effectively work together to share information, make decisions, and solve problems. An active philanthropist and advocate for smart growth, Barbara currently serves on the board of many leading organizations including the Federal City Council, The Economic Club of Washington, DC, DCBIA, and Safe Shores – The DC Children’s Advocacy Center.
