Profile/History

4 Principals. 50 years of Service. Over 5000 Regional Succeses.

Not all geotechnical engineering firms are created the same. GMU Geotechnical has built a reputation over the past 50 years as a trusted consultant for some of the most challenging and recognizable construction projects across Southern California because we do things a little differently – i.e.

Service ExcellenceRegionally ActiveHistory Repeats

Client history and retention attest to GMU’s commitment to service excellence. Our 50 years of service excellence has been recognized by over 50 awards and special recognition, while also providing on-time/on-budget performance. GMU understands that true success of any project is measured by client satisfaction.

These awards serve as living testimony of GMU’s ability to meet the efficiencies and functionality our clients expect and deserve. Acknowledgement of our achievements has come from national organizations such as CELSOC to regional ones such as CalGeo and local chapters of ASCE. We are continually ranked by the County of Orange as one of the top 2-geotechnical consulting firms in Orange County.

Although anchored in Orange County GMU’s project experience and expertise extend to all areas of Southern California from projects in San Diego to the Inland Empire and Santa Barbara. Outside the region we have projects extending from the Bay area and Sacramento to Nevada and Utah. This experience has allowed us to gain the regional knowledge and expertise needed to hit the ground running without costly learning curves.

GMU has been committed to a core set of values since 1967. And while our name has morphed through the years to recognize our growing expertise and changing leadership, we have never lost sight of our dedication to pro-active service, innovation and commitment to our clients.

  • 1967 – We began as Evans, Goffman and McCormick
  • 1978 – Gary Urban joined the firm and became a partner in 1993 when the firm became known as Goffman, McCormick & Urban.
  • 1997 – with the retirement of Jack Goffman and John McCormick, Gary Urban became president and Greg Silver joined the firm as a principal and its vice president.
  • 2005 – with the purchase of Lejman Geotechnical, the firm changed its name to GMU Geotechnical, Inc. and added a third new principal, Mike Moscrop.
  • 2011 – Aron Taylor was added as a principal after 10 years with the company.
  • 2013 – The company is managed by its 4 core principals – Gary Urban, Greg Silver, Aron Taylor and Mike Moscrop.
    • Today, the tradition of pro-active innovation started by John and Jack are carried on with the new leadership. We simply know no other ways of doing things. Other key team members include:

      Mr. Bob Mutchinck – Director of Seismological Services

      Mr. Dave Atkinson – Pavement Engineering Director

      Dr. Ali Bastani – Director of Engineering.
