Lt Col USAF retired. Charlie null and Tyler wood were an excellent team and installed my 7 windows to my complete satisfaction! As a team Charlie was an inspiring leader overseeing the work in detail so there were no errors. There were friendly, personable, professional and thorough. Charlie provides me and my wife thorough description and instructions on the windows. Clear and concise. If there are opportunities for Charlie to be promoted or advanced to more responsible positions he is capable and ready! As we used to say in the military, Promote Him!
