Joan was raised in New York, NY, and earned her Bachelor’s Degree in Biology from The College of Mount St. Vincent, Riverdale, NY, and her Master’s Degree in Public Administration from New York University, New York, NY. She went on to earn her Teaching Credential (Secondary School) from New York State.

Ms. Pesek previously worked as a Laboratory Research Technician and Laboratory Manager of Howard Hughes Medical Institute of Vanderbilt University in Nashville, TN, The Rockefeller University in New York, NY, and New York University in New York, NY.

Joan was loved and cherished by her family and many friends, and she will be sorely missed for her way of making others feel better through her calm, philosophical wisdom and advice. She enjoyed travel and her experiences living and visiting a variety of places in the U.S. and overseas, making lifelong friendships along the way. Joan delighted in trips to the ocean and spending time with her family at the beach in Amagansett. Joan was very interested in cooking, and we will all miss her culinary skills in the kitchen and the many holidays and meals we shared together. Joan also enjoyed swimming with her pool friends, gardening, watching wild birds, and playing Mahjong with her friends in Shanghai and Weston.
