My wife and I recently purchased a home that John built and we cannot speak highly enough of our experience working with him. From the beginning, John was incredibly personable, responsive, and detail-oriented. His selection of both building materials and high-end finishes illustrated his commitment to ensuring the longevity of the construction and luxury quality of the home. Our inspector remarked that of his 20+ years in the industry, he had seldom seen that standard of craftsmanship. Additionally, John was an excellent communicator, remaining responsive for questions even after the sale. We would recommend John without hesitation to anyone looking to build a home.
