Duane F. Hillis, D.V.M., 74, of Lenox died Nov. 3, 2020, surrounded by his family at Berkshire Medical Center after a short battle with heart failure and cancer.

Duane was born Oct. 3, 1946, in Niskayuna, New York, to the late Reginald and Viola Hillis. He graduated from Colonie Central High School in 1964 and attended Cornell University, where he obtained his doctorate in veterinary medicine in 1970. After selling his second veterinary hospital in 1978, he moved to Newton to pursue a career in commercial real estate in the Boston area.
Duane was a committed civic volunteer for the city of Newton, serving as president of Friends of Nahanton Park for 30 years. He was also a board member of the Newton Conservators and assisted with NewTV’s environmental programming. Duane was a leading member of a team of volunteers that successfully applied for Newton Community Preservation Funds to purchase the Newton Community Farm. For this work, the Newton Conservators named Duane and two others Environmentalists of the Year in 2006. Duane received this award a second time in 2016 for his work on the Woodcock Meadow Team.
Duane was a caring and committed husband, father and grandfather. He loved spending time with his family, cheering on his grandchildren at their sporting events, and family meals.
Duane met Mary Reinhart at a fifth-grade band concert. Duane loved to tell the story of how he approached her afterwards to compliment her on the excellent performance. Duane and Mary married July 24, 1967, in Albany, New York.
Besides his wife, Mary, Duane is survived by children Dr. John Hillis and wife Melissa of Jacksonville, Florida, Robert Hillis and wife Elena of Los Angeles, California, Molly Elliot and husband Mark of Lenox, and Maggie Estlinbaum and husband Tyler of Marcellus, New York; grandchildren Gabrielle and Dillion Hillis, Dane, Hannah, Magnus, and Odin Hillis, Mary, Grace, and Jane Elliot, and Ernest and Henry Estlinbaum; and his sister, Nancy Famolari and husband Gene.
