I received a call this morning from one of your best. I rarely ever contact an employee’s supervisor, but I feel that this morning's call was worthy of sending a letter.

Over the past 10 years, I have never been given any reason not to trust Konell's employees. Your crews have always been professional and trustworthy. When they say they will do something, it gets done -- every time. So, once again my faith in Konell Construction has been reinforced by one of your finest.

Thank you for hiring and training great employees!

Konell has and continues to provide a high level of professional service that I can confidently say is "best-in-industry" relative to their local competition. I've used other demolition companies in the past, but Konell is by far the best. I highly recommend you use them for all of your construction and demolition needs, I know I will!

We have been inspired and impressed with the leadership and team work that Konell Construction has offered us while we were in the building phase of our space. Konell staff has brought technical and sound building advice and the suggestions have helped us problem solve some difficult negotiations with various inspectors and the building owner. The Konell team has worked well in teaching the youth that have joined the work days. This direct collaboration has helped several young people become job ready, have job skills, and manage life skills to be successful.
