It All Started With A Passion For Clean Groundwater Supplies.

Tetra Tech

Today, Tetra Tech (Nasdaq: TTEK) is a leading global provider of consulting, engineering, and technical services with $2.5 billion of annual revenue.

The company’s deep technical expertise spans the disciplines of water, environment, energy, infrastructure, and resource management. TTEK solves some of the most challenging problems in those areas for commercial, governmental, and military customers in dozens of nations worldwide.

But when RLH invested in the small privately-held company in 1988, revenue was just $25 million. Along the journey of 100-fold growth since that time, RLH has been a steadfast resource for the management team. Members of our team have served on the Board of Directors continuously since 1988, helping see the company through its initial public offering, numerous acquisitions, global expansion, creation of new business lines, and many other strategic milestones.
