Zikhrono Livrakha ... May his memory be a blessing.

Born on June 14, 1948, in Boston Massachusetts, to Harold and Esther (Davidson) Kornetsky, Ken grew up in Milton Massachusetts and graduated from Milton High School in 1966. A studious child, Ken knew he wanted to be a doctor from an early age.

He pursued a lifelong passion for medicine and service and graduated from Bowdoin College in Maine in 1970. He was one of only 16 students accepted into the first class of the University of Massachusetts Medical School, where he earned his medical degree in 1974. He completed his residency and fellowship in Internal Medicine and Nephrology at the Medical College of Virginia in Richmond. It was here that he met Astrid, his beloved wife of 47 years.

In 1984, Dr. Kornetsky came to Warrenton to establish one of the region's first nephrology practices. For more than forty years, he cared for thousands of patients in Fauquier, Culpeper, and Prince William Counties. He practiced with compassion and integrity, offering care without hesitation to those in need, and in so doing fulfilled the highest ideals of a physician's calling. Recognized as a brilliant mind and unwavering patient advocate, Dr. Kornetsky influenced generations of physicians and earned profound respect for his wisdom, while reinforcing the values of community-centered medicine.

His service extended beyond Virginia through his work with Medical Missionaries of Manassas and the St. Joseph Clinic in Thomassique, Haiti, where he contributed to global health efforts and served as Vice President of the organization and as Director of the clinic since it opened in 2007.

One of Dr. Kornetsky's greatest joys was teaching the students of the Fauquier Jewish Congregation, sharing with them the rich history and profound meaning of the Jewish faith which he so loved.

Dr. Kornetsky is survived by his wife, Astrid; his sisters, Susan Oliver of Hawaii, and Joyce Groemmer and her husband, Peter of Massachusetts; his nephews Daniel Oliver and David Oliver of California; his niece Emily Groemmer and her husband, Patrick Stern of New Jersey; his stepmother Anne Marie Kornetsky of Massachusetts; and his beloved friends and colleagues.

A Celebration of Life will be held on September 15 at 6:00pm in the Parish Hall at St. James' Episcopal Church, 73 Culpeper St., Warrenton. In lieu of flowers, the family requests support for Medical Missionaries of Manassas or the Fauquier SPCA.

Dr. Kenneth Kornetsky will be remembered for his kindness, his love of family, his skill as a physician, his dedication to community, and his generosity of spirit. His laughter and smile will be deeply missed.
