Dianne Lee is Associate Vice President for the Western Region Construction and Project Management business line of AECOM. As part of her role, she focuses on advancing growth across all markets by driving business development initiatives and building industry relationships while establishing market presence and visibility—creating opportunities for AECOM and securing partnerships with all stakeholders.

Dianne has spent over 12 years dedicated to the industry, with her client relationships primarily focused in Southern California. Her areas of expertise are within the Public Agencies, Education, Aviation and Healthcare markets. She has led business development pursuits both internationally and nationally and has been instrumental in the strategy and awards of several significant billion-dollar construction management programs.

She credits Guy Mehula, former Chief Facilities Executive of LAUSD and past President of Parsons, Middle East, for bringing out the best in her, which has been instrumental in her proven growth and success. In addition to her commitment to the AEC industry, Dianne volunteers with several causes that are dear to her. From fundraising for the non-profit California Hospital Medical Center (CHMC) in downtown LA, to serving the homeless at the Midnight Mission, she is relentless in her pursuit of giving back. She is also an SMPS mentor and is currently mentoring a CMAA intern from Cal Poly Pomona. She lives by her personal credo: empowerment - regardless of gender, age, race or status.
