Building upon over a century of successful projects

LEE & Company, LLC was founded in 2008 as a Missouri Limited Liability Company specializing in the planning, design, and deployment of cutting edge infrastructure technology and an engineering based approach to the management of a wide variety of mechanical and electrical equipment assets. The Founder, President and CEO, Gary Lee P.E., took decades of infrastructure engineering experience and applied those principles to the development of a project management approach uniquely formulated to assist in deployment of new innovative technologies.

Having evolved from the century old environmental and civil engineering consulting firm ET Archer, and growing from its technical background, LEE developed a proprietary process (CAPTURE©) to bring the best scientific methodologies and business strategies to the process of maintenance. LEE & Company evolved from a company named Universal Asset Management that bridged the engineering background of Archer with the asset management programs of UAM.

Today, LEE provides a wide variety of consulting services, risk and fixed asset management consultation, modeling and analysis, and independent project management services.


Elmer T. Archer founded ET Archer with a vision of providing electical power to small and mid-size communities in the Midwest. The firm expanded greatly during WWII, but Mr. Archer elected to downsize afterward to maintain the ideal of a small firm working closely with long term clients.


Willis Lee purchased ET Archer from Mr. Archer and worked with his business partner Elmer West on water system projects in Northern Missouri and Kansas. Over the next 40 years, the firm constructed over 100 water systems throughout the Midwest.


Gary Lee, Willis‘ son, joined the firm after finishing his second tour of engineering work for the U.S. Public Health Service. Gary was appointed president in 1978, and he expanded the company‘s services in water & wastewater systems and established 9 new offices throughout Missouri, Kansas, and Kentucky.


Gary Lee, together with Willis Lee, founded Universal Asset Management with a broader range of services and a focus on total asset management. ET Archer was sold in 2006, and UAM became a global enterprise with projects in Missouri, Australia, Mexico, and Hawaii.


LEE & Company, LLC, consulting engineers was founded after the death of Gary Lee‘s long time partner and father of Willis Lee. LEE focuses more on engineering services with particular emphasis in design, project management and risk analysis.

From the days of Mr. E.T. Archer taking a train or horse and buggy rides to council meetings, to LEE pioneering new methods of water system engineering, our firm‘s story has always been one of success. As always, our firm‘s success is embedded in its personnel, the engineers, the technicians, the surveyors, the architects, the support staff that make up the project teams that serve our clients. With our continued influence over our market, LEE‘s reputation as an design and management firm is hinged not only on quality minded professional services, but also on quality execution for our client which will continue to carry LEE‘s success into the next century.
