Thiel Engineering

Our History

Thiel Engineering was founded in 1995 as a one-person firm by Richard Thiel, and ... it has stayed that way! Resisting the ever-present pressures to grow, merge, or be acquired, Richard has managed to hold his high standards of customer service and quality while maintaining a viable business.

After doing work-study with the US Army Corps of Engineers while obtaining his Master's Degree, Richard started his first full-time job as an engineering consultant designing large rock-filled clay core dams with Harza out of Chicago. After several frenzied years in that business, the bottom fell out of the dam world (excuse the pun) and he joined what was then the nation's foremost firm in solid-waste consulting: Emcon Associates. After 8 years of very valuable experience with Emcon, time and circumstance conspired to push Richard to start his own company and service his clients on his own terms. He is now in his 8th successful year as Thiel Engineering.
