Welcome to Toth and Associates

In December 2003, TOTH was established and initially specialized in electric utility engineering. Since that time, we have grown to become a multidisciplinary firm that features electrical, civil, & structural engineers, as well as land surveyors, CPAs, grant writers, and other professional staff working together to serve a wide range of clients. These clients include municipalities, architects, educational institutions, and public & private utilities across the country.

TOTH is committed to providing high-caliber, professional expertise grounded in past experience and shared knowledge supported by skilled staff and innovation. Our staff of nearly 100 individuals includes professional engineers, engineering interns, CPAs, GIS specialists, and professional land surveyors.

We invest our specialized knowledge and experience in building enduring relationships with clients for the good of our communities. We work to develop healthy working relationships with local utilities, cooperatives, contractors, engineers, regulatory agencies, and materials vendors. This collaborative approach to project design and administration demonstrates our firm’s agility and willingness to understand and accommodate the requirements of other project stakeholders.

Across all of the market segments we serve, project owners are seeking well-qualified engineering firms with strong momentum, open communication, and careful attention to the priorities of their clients. At TOTH, we understand the need, and we are eager to be a part of the solution.
