Mark Richard Klauk, formerly of Erie PA, Hudson, MA, and most recently Newton NH, left us on 10/13/06 after a long struggle with illness. He was born on 11/20/1946. Mark was a clinical social worker with an MSW from Columbia University. He had a private practice located on Red Acre Rd in Stow, MA. He also taught fitness at the Thoreau Club and Global Fitness. He leaves behind wife Debra, sons Ryan and Andrew, daughter Erin, and stepdaughter Shane. His parents and siblings live in Erie, PA. All will miss him dearly. There will be a gathering at 10:00 AM on Tuesday (10/17) at the Cremation Society of NH, 243 Hanover St, Manchester, with a service at 11:30 in the chapel. Donations in his name can be made to the DeCordova Museum and Sculpture Park in Lincoln, MA, or to the Juvenile Diabetes Research Foundation. All donations are greatly appreciated. Invited friends are welcome to join us to celebrate his life later that afternoon at Fruitlands in Harvard, MA. We mourn the loss of a dear and cherished friend.
