"The nature of our business requires that we work in collaboration with others to achieve our desired results. Thus, we welcomed J. M. O'Reilly & Associates to our development team. They worked with us from project conception to project completion, contributing surveying, engineering, and environmental expertise along the way. They were responsive, creative, and their work was first-rate. They understood our objectives and their guidance was invaluable. Importantly, they worked well with other firms on our development team. Based on our four-year experience with J. M. O'Reilly & Associates, I look forward to engaging the firm on another project in the near future."
