Our Firm

It is our strong belief that resisting shortcuts early saves our clients time and money in the long run.

We are hands-on and face-to-face with everyone, from clients visiting our office to subcontractors in the field.

Our story began in 1988 when Tim Johnson began to envision a civil engineering firm that could operate under the same professional standards he held closely as his own: attention to the details, commitment to a project even when the status says ‘completed’, and the kind of open, honest communication that’s based on building relationships, not just signing contracts.

Tim’s experience has deep roots in Oklahoma City, where he began as a civil engineer for The City of Oklahoma City in 1976. In 1981, he joined local civil engineering firm Smith-Roberts & Associates and eventually became vice president and co-owner. When he left the firm in 1988, he stepped into entrepreneurship with little more than four employees, a handful of prospective projects, and a growing reputation for excellent work done with integrity and tenacity.

In the years since, Johnson & Associates has grown to include full-service surveying and urban planning departments and a diverse staff that includes specialists in stormwater analysis and design, construction supervision, and traffic engineering.

In 2014, the company ownership expanded to include Tyler Muzny, a registered engineer, who started as an intern in 2003 as he finished his engineering degree.
