    To John and all Mary Ann’s family – I knew Mary Ann in high school and wanted you all to know how much of an impact she made on my life. She patiently and tirelessly tutored me through my 3rd attempt to get through high school chemistry and succeeded! She made all the difference in my life and all her successes inspired me to keep moving forward academically. I also remember her lamenting the lack of boys interested in her in high school and I assured her that college boys would appreciate her because she was smart. Looks like she found that guy that I knew was out there for her. She was very special and I am glad to have known her, she will be missed.

    I was saddened to learn of Mary Ann’s death. She and I were great friends in high school especially in Junior and Senior years. Our special group of friends had so much to share those wonderful time in all our lives both at LHS and out-and-about in greater Syracuse. I remember two truly memorable events that stand out for me – “Senior Skip Day” at Brennan’s Beach with all our friends playing hookie for probably the first time in most of our studious lives, and the senior prom, with that terrible iced coffee the only thing to drink, at the dance where it must have been 105 degrees. Since it was so hot, we were all energized so much we attended a group after party given by one of our friend’s parents and finally ended up at Long Branch park at the play ground at sunrise (with dresses and tuxes on). I still have the picture of Mary Ann in her peach colored dress and me in my tuxedo at the front of my photo memory book.

    John, you and I have never met, but you must be very special for Mary Ann to live her life with you. It feels kind of “mortal” down here, but now i’m sure that my favorite toxicologist is making heaven a safer place for all her friends and loved ones. Of course I also “see” Lady is following her all around and “Mr Heindorf” is driving her from site to site in his wood-paneled Aspen.

    My thought and prayers are with you and her family
