“For more than 12 years, I have reviewed the numerous applications prepared by Keith Simpson for permission to construct in, and close to, environmentally sensitive areas. His applications with supporting maps, drawings and documentations were extremely well prepared and his presentations before the agency were concise and thorough. He, and his office, responded to questions, comments and requests for further information from the agency in a most professional manner. It was obvious to my agency that he was highly respected by the lawyers, engineers, surveyors, soils scientists, site contractors and other professionals with whom he was working in connection with these applications, which speaks well of his professional reputation and the enduring quality of his many projects. Keith is a professional of the highest order and a true gentleman whose ethics, and honesty are above reproach.”
