I have worked with Mark and MEC for over 20 years now, and couldn’t be happier with our results! Besides the 10-15 transactions that he has supported for us over this time, Mark has provided incredible service to dozens in my network with the agility of a small business, but all the capabilities embodied in much larger firms
