About the Company
Kimley-Horn
Kimley-Horn keeps two groups of people at the center of its business: its clients and its staff. Past president Ed Vick said, "We have no reason to exist except to serve our clients." That intense focus on providing quality to the people we serve has made Kimley-Horn one of the nation's top consulting firms in every discipline we practice.
But the firm's core purpose, articulated by its leadership and lived out daily, is "to provide an environment for our people to flourish." We know that people are fulfilled, motivated, and challenged in different ways. In order to foster our individual aspirations, we support our people as they grow into roles and take on responsibilities that are important to them. Growing professionally, having fun with our colleagues, and finding satisfaction in our work are central to our way of life.
To that purpose we add core values: "honesty, integrity, and ethics; exceptional client service; high expectations; sharing and caring; sustained profitability." Our core values and core purpose provide a foundation for the way we approach our business. Our vision is long-term and our expectation is always to perform with quality, for the sake of both groups at the center of our firm.
Through their work, our people discover untapped talents and interests. At Kimley-Horn we work hard to allow that to happen. We have college students who started as traffic engineers now working on ITS projects. We have former administrative assistants who are now human resources professionals and former marketing coordinators who are now transportation planners.
We provide the environment. We want you to take advantage of it and flourish!
