About VERTEX

With three employees and a strong sense of urgency, VERTEX caught the attention of several Fortune 100 companies in 1995 as a go-to firm for traditional and forensic AEC services. In 2001, Tetra Tech, Inc., a perennial top ten AEC firm in the US, acquired the company. VERTEX flourished with Tetra Tech until 2005 when VERTEX’s management team led a buyback to take the company in a new direction with the insight gained while being a part of a multibillion-dollar public firm. VERTEX is now an ESOP with hundreds of employees that work out of 25+ offices throughout the globe and we have completed over 50,000 projects to date. Our value-focused and responsive approach will remain unchanged as we endeavor to double in size over the next decade.
