"We have always been very satisfied with the courtesy, skill, and professionalism of your technicians. Our previous positive experience notwithstanding; we feel obliged to report that our recent experience with Kyle Prince was in a class by itself. His thoroughness, knowledge, and expertise were at a standard well above any prior service we have experienced. He has an uncontrived natural gift for putting customers at ease which is augmented by his willingness and ability to answer questions and explain what he is doing and why. The fact that he is a young man makes the above traits all-the-more more impressive. In future we would definitely prefer Kyle to handle ALL of our maintenance and service needs! He would make an excellent trainer for your new technicians. He is a true credit and invaluable asset to the John Betlem reputation for quality of service. Any professional, and/or compensatory advancement that you might choose to offer this fine young man would be well deserved! Thanks! "
