I had opportunity to get to know Mark in 1994 when I went to work at Marquette as an academic advisor for student-athletes. When I was moving to a new apt...Mark volunteered to help me and my fiancé. I have vivid memories of great conversations we had about life, athletics, education, etc. My heart goes out for his family...though I have never met Erin and the kids...I feel as if I have been privy to their life through Facebook. Sending big hugs!
