For nearly all of Mark’s adult life, his greatest passion has been supporting the work of the National Health Association, the oldest organization in the Country advocating the benefits of a whole-food, plant-based diet and lifestyle, something it has been championing since its founding in 1948. He became a member of its Board of Directors when he was 18 years old and was elected its youngest President in 1977 and served two consecutive two-year terms. He returned to serve two more terms in the mid 1990’s and then once again from 2004-2005. In March 2012, he was again asked to serve as President and has continued in that role to this day.
