About
Terry Giles is president and founder of Giles Engineering Associates, Inc., the Waukesha geotechnical, environmental, drilling and materials-testing consultant first-party and directory copy date to 1976.
The firm's Wisconsin page publishes the Central/Eastern Region office at N8 W22350 Johnson Drive, Waukesha, WI 53186, phones 262.544.0118 and 800.782.0610, and a general info inbox. ACEC Wisconsin lists the same Johnson Drive suite A1 lock and names Terry and Joyce Giles among the contacts.
The Daily Reporter's February 7, 2003 profile said Giles started the firm in 1976 with his wife Joyce, then secretary/treasurer, after a bounced paycheck ended a prior job; they worked from a dining-room table, rented a Waukesha office after about nine months, built their own offices in 1980, and a decade later moved onto Johnson Street. That piece said the company then employed about 150 people in seven offices (Waukesha, Madison, Anaheim, Atlanta, Washington, D.C., Dallas and Orlando) and that son Troy was also in the business. A Colorado PE listing names Terry Lee Giles at the Johnson Drive suite.
Named president and founder of a single Waukesha-headquartered national soils-and-environmental shop with a documented 1976 start and a published Johnson Drive lock makes Giles the engineering principal on this slate. Joyce Giles remains in the founding-generation contact list. Work email locked from the Apollo-first pass.
