Colonie - Denise M. Guerin, 71, died Monday, January 24, 2011. She was born to the late Dr. Louis Chatel and Jeanne Chatel in Montreal, Canada on November 24, 1939.

She was a loving, caring wife and mother. In 2005, the Jocelyn clinic honored her with an award for living with diabetes for 50 years. Denise was an active member of Unity Church in Albany, the Insulin Pumpers Group and the Cathedral Food bank. Denise is survived by her husband, Charles F. Guerin; son, Charles L. Guerin; sister, Louise Long; and brothers, Jean-Louis Chatel and Jacques Chatel. Denise's funeral service will be held at 3:00 pm, Sunday, January 30, 2011 at the Reilly & Son Funeral Home, Colonie.
