Glenn William Heinze

Dr. Glenn William Heinze, age 67, dentist and Shelter Island resident since 1993 and devoted father of six, passed away Dec. 7, 2017, at Stony Brook University Hospital.

Born at Jamaica Hospital in Jamaica, N.Y. on July 3, 1950, five minutes before his twin brother Gary, Glenn was raised in Bellerose, Queens, by his loving parents George Charles Heinze and Doris Carroll Heinze (née Doris Hand Carroll).

Glenn earned his Bachelor of Science degree from Adelphi University in 1973 and went on to graduate from The Fairleigh Dickinson School of Dental Medicine in 1977 with his Doctor of Dental Medicine (DMD) degree. He then was chief resident in general and hospital dentistry during his two-year post-doctoral residency at North Shore University Hospital in Manhasset. From 1979 until 1995, he taught in North Shore University Hospital’s general practice residency and was also chief of the special needs program, where he treated special needs patients in the dental clinic and in the operating room. Glenn became a fellow in The Academy of General Dentistry in 1985 and went back to teaching general practice residents at North Shore University Hospital from 2006 until 2014. He had three successful practices in Glen Cove, Sag Harbor, and ultimately, Shelter Island.

Glenn will be deeply missed by his six children, Jillian Elizabeth Heinze of Astoria, N.Y., Margaret Ellen (Robert) Farnen of Wilton, Conn., Kelsey Lynne Heinze and Rachael Christine Heinze, both of Saint Augustine, Fla., and twins, Christian Carl Heinze and Luke George Heinze, both of Bradenton, Fla.; two grandchildren, Kassidy Lee Fowler and Robert Kelly Farnen; and two brothers, Gary George Heinze of New York, and Gregg Richard Heinze of Garden City. His sister, Jill Ann Heinze predeceased him by 59 years.

A memorial service is planned to begin at 11 a.m. Saturday, Jan. 13, 2018, at The Presbyterian Church in Garden City. A reception with refreshments will immediately follow the service at the church. There will be a private interment held at Flushing Cemetery at a later date.
