Elizabeth Solís; CEO & Owner

Ms. Solís has 30 years of professional experience in public works. She began her TSG career at the ground level as a Compliance Analyst and field interviewer, progressing with increasing responsibility in each operations role through Senior Project Manager and Vice President of Operations. Her passion for the work is driven by the real world impacts our services have for the people who build and benefit from our clients’ development of significant new infrastructure projects. Building on her professional development through growth opportunities like APTA’s Leadership Program and recent completion of the Stanford Graduate School of Business Latino Entrepreneurship Initiative, she looks forward to guiding the future of TSG for growth through staff development, service expansion, and new market exploration. This past year, Ms. Solís implemented the firm’s official Integrity Policy and has focused on creating a more communicative and collaborative space for all employees. Ms. Solís is also President of the TSG Foundation, a charitable enterprise focused on supporting causes in the areas of youth development, scholarships, in-need individuals, health, and animal welfare. This year’s foundation contributions were directed toward students in need facing food insecurity.
