A STEP IN TIME

Celebrating Over 50 Years of Transforming Ideas into Reality: The Sambatek Story
Sambatek is built-to-last. It stood the test of time, with its stellar reputation and legacy growing over the past five decades.  While we improvised our brand name to reflect changing times, the core of who we are remains steadfast in the success of our clients and colleagues who have been with us through this amazing journey. Here’s our story:

The Beginning: A Foundation Laid in 1966
In 1966, U.S. Navy veteran Williams (Skip) McCombs, PE, and professional land surveyor Dickman Knutson embarked on a remarkable journey, founding McCombs-Knutson Associates in Plymouth, Minnesota. Little did they know that this modest beginning would lay the foundation for a legacy of excellence in civil engineering and surveying services.

Evolving with Excellence: The 1980s and 1990s
As the years unfolded, the firm evolved into McCombs Frank Roos and Associates, Inc. (MFRA), rapidly expanding its municipal and private land development client base. The firm became a beacon of innovation and expertise in the Twin Cities and Upper Midwest.

From Turbulence to Triumph: 2000s
The Great Recession took a toll on several firms in our industry. It was a true test of what our firm is made of – a client-centric, employee-centric company of associates who are tenacious in preserving and safeguarding the reputation and legacy that is built to last. As they say, when the going gets tough, the tough get going. Sirish Samba, PE, emerged as the President and CEO to help maneuver the firm through turbulent times. Sirish championed transitioning the firm from a private equity group ownership model to a firm owned and operated by its key leaders. This pivotal moment paved the way for our DBE and MBE certifications, opening doors to Transportation/Transit markets.

The Rise of Sambatek: 2014
2014 marked a significant milestone as the firm emerged as the 48th Fastest Growing Civil Engineering firm in the Country. Reflecting our expansion into new markets and territories, our headquarters found a new home in Minnetonka, symbolizing our commitment to growth and innovation and the emergence of a new brand – Sambatek!

A National Presence: 2019
Sambatek continued its growth trajectory, graduating from the DBE program, and opening a branch office in the Dallas-Fort Worth area in 2019, solidifying our presence in the market. This expansion was a testament to our dedication to better serving our clients across diverse regions.

Joining Hands with Commercial Site Design: 2022
In 2022, Sambatek expanded its capabilities by acquiring Commercial Site Design, a firm based in Raleigh, North Carolina, specializing in multi-unit rollout and development services. This strategic move positioned Sambatek to expand its national footprint further.

Our Commitment to Excellence: A Dynamic Future
Looking ahead, Sambatek is poised for a dynamic future. Our commitment to excellence, sustainable solutions, and client success will continue to drive our growth and success in the future. Join us in celebrating over 50 years of Sambatek’s entrepreneurial spirit and the countless stories of transforming ideas into reality. Here’s to the next 50 years of innovation and growth enhancing the lives of our colleagues, clients, and the communities we live-work-play.
