I pursued the opportunity to work with ATC based on several factors: I liked the national presence of ATC and the ability for the firm to service clients across multiple regions, ATC had a good reputation in the local market, providing the basis for growth and the people. I know several people with ATC and appreciated that fact that they liked where they work, the people they work with and the projects they are working on. The key, for me, was finding a great place to use my experience, mentor staff, and still have room for professional growth.

My favorite things about ATC are the great people I work with and the diversity of work we perform. Everyone at the Dallas office is always willing to answer questions and teach me about the industry. I am also able to learn about and be utilized in both the Environmental and Building Sciences Departments.
