“As many of HNTB’s clients are being challenged to address inequities at an increased level of accountability and transparency by the constituencies they serve, we want to assist in strategizing and delivering effective, innovative solutions that lift historically underserved communities for a sustainable future,” Mendes said.
With more than 35 years in the industry, including five years with HNTB, Mendes has held numerous significant leadership positions.

She advocates changing the conversation around diversity and inclusion from a requirement to a competitive advantage, emphasizing the linkages between diversity and innovation.
Throughout her career Mendes has been appointed to many professional association boards and committee leadership positions. Her notable achievements include serving as chair of the APTA’s Legislative Committee to develop Federal Transportation Bill Reauthorization recommendations; receiving the American Road and Transportation Builders Association’s Ethel S.
