"I am very thankful that I can consider J. M. O’Reilly part of the Habitat development team. When I came on board at Habitat the J.M. O’Reilly projects were the ones that went smoothly. You were always on top of deadlines, and always communicated well. Development projects are never without their issues, but the key is to identify issues in advance so that can be resolved before they turned into large problems. And we count on J.M. O’Reilly to do just that. As Habitat accelerated our development pace, Keith has been with us. He has met every deadline we’ve set, even the absurd ones, and has help us move some spectacular projects forward. Besides having a great work attitude, he shares our mission to create community housing, and we very much appreciate all that he, and the J. M. O’Reilly team does for Habitat. Thank you."
Leedara Zola Director of Land Acquisition and Permitting Habitat for Humanity of Cape Cod

"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."
