Pellegrino’s installed Phone Master 7 months ago. The instillation itself was a very easy transition, and didn’t interrupt our business. Cliff was available for the next few weeks to train the staff on how to use the system, and work out any bugs. We even threw him a couple unexpected curves that he handled promptly and graciously. Cliff checks in with us regularly, and answers our questions with a smile. His friendly demeanor is a pleasure to work with.
