"Konsor Enterprises completed our home in July of 2004. As first time builders we were very leery of the building process and builders in general. John and Joanna meet or exceeded all of our expectations. They are hard working, fair, and honest professionals that we are so fortunate to have stumbled upon. Not only did we enjoy working with them but the team of craftsman that they have aligned themselves with are exceptional. Their experience, attention to detail and caring personalities made our home building experience wonderful. In July our home will be a year old and so far their follow through has also been great. We would not only recommend building with Konsor Enterprises we hope to build our next home with them."
