I've known Kevin for more than a decade and worked with Kevin on a variety of non-profit activities for the past five years. Kevin has drive and a commitment to excellence in everything that he does. What impresses me most is his ability to work across generations and personality types to gain consensus on challenging issues, and then drive to a positive resolution. He always seems to have the end result front and center in his thinking. This helps him see past potential roadblocks and drive to the desired outcome. He's organized, methodical in his approach, and detail oriented. Best of all, Kevin is simply a great person. Someone you genuinely like to be around because he makes you feel important, and puts your welfare equal to his own. In client service, I can think of no better characteristic.
