Dennis and I worked together for a short period of time at Zayo. I had the privilege of transitioning my account base to Dennis as I was leaving for another position outside of the company. We spent many weeks visiting customers in order to introduce and familiarize so the transition would be seamless. Dennis was very professional and customers loved his easy going and transparent style. Dennis is a true professional in every sense of the word and he gets my highest recommendation for integrity and commitment to the customer.
