Ayres Associates hires and cultivates smart project managers who stretch their clients’ dollars and quickly handle problems while always focusing on building long-term relationships with clients and regulators.

Ayres Associates’ foundation of personal, responsive service was established in 1959 when Owen Ayres founded the firm in Wisconsin. Owen, a former B-24 bomber pilot, began the firm with five employees, specializing in general civil engineering.

Ayres Associates remains dedicated to employee ownership, a structure that began in 1959 and continues today. This enables all employees to benefit directly from company performance. We practice open book, open door, and open communication policies with our employees.

Ayres Associates has grown into a nationwide multispecialty professional services firm of about 300 employees providing services from 11 offices in four states.


Our Community

We believe we have a duty to be good corporate citizens. Whether it’s through participating in a professional organization or organizing a local food drive, we are committed to being involved. Across the nation, our employees are engaged in civic and charitable functions including United Way, United Cerebral Palsy, Engineers Without Borders, and many local organizations.


Big Firm, Small Footprint

While Ayres Associates takes pride in making a big impact through designs that meet clients’ needs, we strive to minimize the impact our own operations have on the environment. Ranked the 321st largest design consulting firm by ENR magazine, Ayres Associates not only incorporates environmentally responsible features into the designs it provides to clients, but also uses dozens of energy-saving and waste-reducing practices each workday to reduce the footprint of our offices.
