Right from the start, Keystone was a pleasure to work with. The opening presentation from lead engineer Chuck Hays was professional and well presented. He was able to answer all of the Board of Directors' questions in a clear and direct manner and the proposal and report was detailed, thorough, and easy to comprehend. What is more, Keystone followed through with their commitments.

The contractor was held to strict standards. Quality assurance was consistent and precise. Invoices were submitted in a timely fashion and were accurate. Change orders were easy to understand and precise in their cost. Of particular note was Mr. Hays' solid leadership and personal interest in getting the job done right, and that no detail, no matter how small, was left unattended. He was informed, experienced, and, something of personal concern to me, he was accessible. That type of commitment to service is impressive.
