Our History
In the early 1980s, three talented individuals, Bob Felsburg, Steve Holt, and Arnie Ullevig saw an opportunity to practice a profession they loved while providing like-minded individuals a place to foster and offer transportation planning, traffic engineering, and design services in Colorado. With only their vision and reputations to start with, they formed Felsburg Holt & Ullevig. Resolute on creating a space where culture was at the forefront, the firm was built on the following objectives:
-
Advance the profession by providing high-quality state-of-the-art planning and engineering services
-
Develop a highly qualified and committed staff of good people (personally as well as professionally)
-
Create an environment in which members of the firm enjoy what they do and where they work.
As the firm continued to grow, it provided an excellent forum for Bob, Steve, and Arnie as entrepreneurs to practice their passion while giving back to their communities. The FHU brand continues to thrive and cement its presence in the A/E/C industry.
FHU's Founders
Robert W. Felsburg, PE
Over the course of an eminent 40-year career, Bob Felsburg was a recognized and respected transportation planner and engineer, managing major multimodal transportation studies, plans, research efforts, and engineering projects throughout the United States, with a focus on the Rocky Mountain region and the Midwest. He helped to guide FHU for nearly 30 years, during which time FHU grew from a single-office, three-person firm to a four-office company with more than 120 transportation professionals. Bob was committed to enhancing the engineering community, serving as President and National Director of the American Council of Engineering Companies-Colorado (ACEC-CO). In 2012, he was the recipient of the Orley O. Philips Award, the highest honor given to an engineer each year by ACEC-CO. He also remained active as an advisor to the College of Engineering at his alma mater, Penn State, and in 2014 was honored as Outstanding Engineering Alumnus by the University.
Stephen A. Holt, PE
Steve Holt had a distinguished career that spanned more than 50 years in the planning, design, and implementation of major transportation systems throughout the United States as well as internationally. Although he spent much of his career in Colorado, Steve also lived and worked in unique places like Alaska and Ecuador. He guided the growth of FHU’s design practice, applying his skills honed by working for federal and state agencies, as well as several international consulting firms. He was a recognized leader among numerous professional associations, including the American Council of Engineering Companies-Colorado (he also received the Orley O. Phillips Award) and the Colorado Contractor’s Association. Steve’s vast knowledge of Colorado’s transportation system led him to be appointed to Blue Ribbon Panels on transportation by three governors, and he was presented the prestigious Roderick L. Downing Award from the Colorado Transportation Conference in recognition of his outstanding contributions to the advancement of the transportation system in the state. Following Steve’s passing in 2024, FHU established the Stephen A. Holt Memorial Endowment Scholarship Fund at his alma mater, the University of Colorado Boulder. The fund honors Steve’s contributions to engineering and public service by supporting undergraduate students in the College of Engineering and Applied Science. Steve’s legacy continues through the firm he helped found, the professionals he mentored, and the future engineers supported by this scholarship. His name and contributions remain an enduring part of FHU’s history.
Arnold J. Ullevig
A native of Zumbrota, Minnesota, Arnie Ullevig earned his Bachelor of Civil Engineering with distinction from the University of Minnesota in 1967. He began his 35-year professional career in Minnesota before moving to Colorado in the early 1980s.He joined Bob and Steve in 1985, completing the firm’s original partnership of FELSBURG HOLT & ULLEVIG. Over the course of sixteen years with FHU, Arnie was a driving force in FHU’s development as a leader in transportation planning and large multimodal corridor studies. His communication skills, both verbal and written, made him a particularly effective leader of multidiscipline planning and design teams. This work contributed to the evolution of project programming techniques to meaningfully incorporate the goals of citizen stakeholders and the constraints on local policy makers into technical work programs. Successful projects were completed in metropolitan sub-areas, urban counties, front range municipalities, and resort ski areas. He is now happily retired in Arizona. In honor of Arnie, who passed away in the summer of 2026, FHU is working with his alma mater, the University of Minnesota, to establish a scholarship in his name. The scholarship will celebrate his passion for transportation and support the next generation of transportation professionals. Arnie’s legacy lives on through the firm he helped shape, the communities influenced by his work, and the many people who benefited from his leadership and unmistakable sense of humor. His contributions during FHU’s formative years remain an important part of the firm’s history.
