Gredell Engineering Resources, Inc. (GER) was founded on the principle of working closely with clients to meet their project goals while providing quality services in a timely manner. Client loyalty and referrals are proof that we have held to this principle.
GREDELL Engineering Resources, Inc. (GER) offers civil engineering design with an environmental focus. GER was founded in 2001 by Thomas R. Gredell, P.E., BSCE, MSCE. After graduation from the University of Missouri–Rolla, Mr. Gredell worked for the state of Missouri’s solid waste management regulatory permitting program for 12 years. Prior to starting GER, he worked nine years for private consulting firms, first as a project manager and vice-president of a Missouri consulting firm from 1992 through June 1998, then followed by 2.5 years as a project manager for a regional Midwest consulting firm.
GER has experienced steady, controlled growth since 2001. Based in Jefferson City, we have branch offices located in Springfield, Missouri, and Olathe, Kansas. The Jefferson City office is strategically located within 1 mile of the Missouri Department of Natural Resources (MDNR) headquarters and their Elm Street office. This location provides GER with central geographic access to the state of Missouri and the state regulatory agencies.
Since our beginning in 2001, GER has assembled a diverse team of highly qualified personnel to assist you with your environmental projects. Our senior staff represents over 200 years of combined environmental, engineering, geology, and geotechnical experience. We have completed waste facility designs, geologic evaluations and assessments, subsurface investigations, and environmental permitting and compliance services to a variety of closely held private companies, public companies, and government clients.
Diligent, conscientious project management is the key to GER’s success and to our client’s satisfaction. Our extensive technical and regulatory knowledge and experience allow us to see the big picture while focusing on the client’s project objectives as well as the intricate details inherent in environmental design and regulation. As consultants, our approach is to work closely with and as an extension of your staff to assure the end result meets your needs and the requirements of your project.
