Mark was always a great friend in high school and college. I lived with Mark in a 2 bedroom apartment during our second year at UVA. He introduced me to some nice vegetarian dishes. We had a lot of laughs that year playing golf, cramming for finals, playing scoring anagrams and just hanging out with friends. I hadn’t seen Mark since college days but talked to him once on the phone after his move to Mexico. We talked about living life outside of the U.S. I really admire Mark’s work in conservation and preservation and feel very lucky to have had him as a friend and classmate.
