Who Founded Tetra Tech?
Founders and Early Ownership traces back to Henri J. Knezevich, who founded Water Resources Engineers in 1966; early equity was concentrated among a small group of senior engineers with Knezevich holding the largest stake to preserve technical direction.
Founding
Henri J. Knezevich established the firm in 1966 as Water Resources Engineers, focusing on water modeling and resource management.
Initial Ownership Model
Ownership followed a private partnership model typical of 1960s engineering firms, with equity held by senior engineers and technical specialists.
Concentration of Equity
Knezevich retained the largest share to maintain directional control; early distribution prioritized technical excellence over rapid expansion.
1977 Acquisition
In 1977 the company was acquired by a major conglomerate, becoming a corporate subsidiary and folding founding equity into the parent structure.
Management Buyout 1988
In 1988 a management buyout led by Dr. Li-San Hwang returned the firm to private ownership, with equity allocated to senior executives and managers.
Post-MBO Ownership Structure
Employee and management ownership included buy-sell clauses and vesting schedules to align technical staff with long-term profitability.
