Just now learned of Mark's passing. He was a class ahead of me at Campion and at Xavier, and I remember him as a calm, soft-spoken, and kind man. He sometimes helped me get through organic chemistry class. I had no contact with him lo these many years, but can only offer my condolences to the family. From the accounts herein, it is certain that he became the honest, devoted and sincere doctor that I always knew he would become. His good deeds will remain forever. May he rest in peace.
