 I have found Luke to be a ‘true professional’ in my dealings with him over the last 10 years. His prompt response is truly appreciated. Few IT Professionals have Luke’s thorough analytical approach to troubleshooting. He will take action only after understanding how the task will impact the entire system ensuring that his Action Items are meaningful. You can count on Luke.

 Luke is one of the best software engineers I've had the pleasure of working with. He listens, and works very hard to achieve whatever he is asked to or he sets his mind to. He also loves to learn, knows much, knows many computer languages, and is very humble about it. He has a unique way with words where he can simplify a concept and quickly understands principles used in business and programming.
