"We have worked with Douglas Mayfield and ADU Architects for many years. We have found Douglas, Faizan and the staff to be knowledgeable, responsive and easy to work with. They also work well with city staff and other contractors, which can be a challenge. We give our whole-hearted endorsement to Douglas, Faizan and the firm."
