JMT has evolved significantly over the past four decades. The firm was originally founded as a Professional Association of partners and associates in 1971 by Charles Johnson, Michael McCordic, and Bruce Thompson under the name of Johnson, McCordic & Thompson, P.A., in Silver Spring, MD. The company focused on planning, engineering, and surveying for residential and commercial projects. In 1978, a second, similar private development office opened in Fairfax, VA.
In 1979, Fred Mirmiran joined the partnership with the goal of expanding into the public works market by focusing on transportation engineering for federal, state, and local public agencies. In 1980, JMT expanded its public works market into Maryland, Pennsylvania and Virginia, and the name of JMT was changed to Johnson, Mirmiran & Thompson. Throughout the 1980s and early 1990s, JMT developed into a multi-modal transportation firm providing infrastructure improvements for:
- Highways and Bridges
- Rail and Transit
From the mid-1990s, JMT continued to diversify our markets to include services for:
- Buildings and Facilities
- Water/Wastewater and Utilities
- Federal Programs
- Information Technology
In 2011, JMT became a 100% Employee-Owned Company. Our employee owners have a vested interest in the success of our projects.
Today, JMT provides consulting services to a varied client base of public and private entities. This diversification of markets and services has resulted in considerable geographic expansion, which allows JMT to provide services across the United States.
JMT’s enduring commitment to provide clients with services of exceptional quality has led to tremendous organizational growth as well as opportunities for us to join with firms of similar values and culture. JMT’s expansion geographically and by discipline has been primarily organic. However, we have also used mergers and acquisition as a growth strategy. We completed our first merger transaction in 2007 – after 36 years in business. Since that time, the following firms, each of which provide exceptional capabilities, have joined JMT:
- Atlantic Engineering, LLC; Kinnelon, NJ
- Barr & Prevost (engineering design and bridge inspection practices); Cincinnati, Cleveland, and Columbus, OH
- Bayside Engineering, Inc.; Tampa, FL
- GBF Engineering, Inc.; Fort Lauderdale, FL
- Kennedy Consulting, Inc.; Georgetown and McKinney, TX
- Kupper Associates; Piscataway, NJ
- R. Kenneth Weeks Engineers, LLC; Norfolk, VA
- Rubeling & Associates, Inc.; Towson, MD
- The Spectra Group, Inc.; Virginia Beach, VA
- Tidewater Environmental Services, Inc.; Charleston, SC
- Trumbull Construction Management Services; Pittsburgh, PA
We have provided planning, design and construction management services for many major award winning projects in the United States as highlighted in the Project Portfolio and Awards & Honors sections of our site.
JMT has improved our ENR ranking for the "Top 500 Design Firms" from #464 in 1995 to our current ranking of #67. The founding philosophy of the firm, exceeding client expectations with the highest quality of work, continues to be the key element of our success. A successful project is achieved by thorough analysis supported by individual attention and the extensive professional and technical experience of dedicated employees.
JMT is certified to ISO 9001:2015, an internationally-recognized standard for quality management and organization excellence, further demonstrating our commitment to quality and customer satisfaction to our clients, business partners, and employee owners.
We at JMT are proud of our history and look forward to the future.
