President 713.266.6900


Dennis W. Petersen, P.E., is the President of planning, engineering and program management firm Lockwood, Andrews & Newnam, Inc. (LAN). In this role, he is responsible for both the firm’s strategy and day-to-day operations.

Petersen, who became LAN’s President in 1997, has a simple leadership philosophy. “Leadership is first and foremost about getting things done,” he says. For the past 18 years, Petersen has lived this philosophy by leading the firm to success and profitability every year.

Petersen’s LAN journey began in 1980 when he joined the firm as a project engineer. In the next 16 years, his technical, analytical, organizational and people skills helped the firm win commissions in the oil field services, aircraft, infrastructure and environmental markets. He quickly rose to project manager, program manager, vice president and eventually to President.

Since becoming the President, Petersen has diversified LAN into multiple markets of infrastructure, transit and transportation, and enhanced its ability to provide engineering services around the country. Under his results-oriented leadership, LAN has managed major projects such as the Houston Surface Water Transmission Program, VTA/BART Silicon Valley Berryessa Extension near San Jose, Calif., Lake Huron water intake project for Karegnondi Water Authority in Michigan, and the Miami-Dade Water and Sewer Department’s comprehensive water infrastructure and assessment program.

In March 2014, he was appointed as the President of LAN’s parent company LEO A DALY, an internationally-renowned architecture, engineering and interior design firm with a vast portfolio of iconic projects (LAN merged with LEO A DALY in 1991). Petersen now spearheads both LEO A DALY and LAN brands.

Petersen also has a strong interest in community service. As a leader on the Bay Area Houston Economic Partnership’s executive committee, he works with investor companies, business professionals, local governments, and educational institutions to stimulate economic development and employment in southeast Texas. He contributes time to the University of Houston, Cullen College of Engineering, serving as a mentor to help guide graduates preparing for the workforce and also to help with its leadership board to gain recognition for the college. The college recently recognized Petersen as a Distinguished Alumni.

Petersen also is actively involved in the AEC industry, serving organizations such as the American Council of Engineering Companies, Design Professionals Coalition and the Texas Council of Engineering Companies.

As a member of the Texas Space Leadership Council, he worked with honorary chair Gov. Rick Perry to promote and integrate new space technology. In recognition of his expertise and leadership, several mayors and county commissioners appointed Petersen to serve on transition teams to bring newly-elected officials up to speed on the state’s infrastructure and chart initiatives for the future.
