"So much of our world today is consumed by negative thoughts and communication, and rarely is time invested to share positive experiences. With that in mind, I would like to express my gratitude for the level of professionalism, quality of installation, attention to detail, timeliness, and courtesy provided me during the course of the replacement at my residence. Thank you Darren and all of the Doty team for restoring my trust in the contracting world!"
-Lynne, Grand Rapids (Oct 2011)
