“11/06/24. This is the fourth project that B.A. Morrison has done on my residence. Construction Supervisor Dylan's supervision was truly impressive, tending to every detail: staffing, supplies, oversight, coordination with the county inspector, and many other tasks. He was patient, communicative, flexible, and visited the job site personally usually twice a day. Carl, the principal workman on the project, cannot be commended highly enough. Carl's range of experience in every phase of this project was nothing short of remarkable, whether it was plumbing, tiling, painting, or any other task. There was no problem that Carl could not solve out of his extensive experience. He was knowledgeable, efficient, fast, and helpful above and beyond, accommodating, and displaying a remarkable attention to detail. He took great pride in his work. Nelson, Miguel, and Ivan too were efficient and hard working. They kept the job site clean after each day's work, and arrived punctually at the start of each day's work. Punctuality is a rare quality these days, but every day, like clockwork, the B.A. Morrison truck(s) pulled up just as my clock was chiming 8 a.m.! B.A. Morrison is clearly dedicated to providing a superior product. The project was completed more quickly and with fewer complications than I had anticipated.“
