Stephen grew up on the family farm in the Town of Binghamton and it always remained a huge part of his life. He was physically fit and continued to chop wood on his land well into his eighties. He graduated from Binghamton North in 1950. He served in the United States Air Force from 1952-1957 during the Korean Conflict. He was honorably discharged and became a member of Disabled American Veterans. He always said he did the best he could with what he had and was always ready to lend a helping hand to all. After serving, he worked for New York Telephone and then the Postal Service for 25 years. He was a quiet, humble and generous man that loved his family very much. He was a proud member of Ss. Peter and Paul Russian Orthodox Church, Endicott and their R Club where he helped out wherever he was needed. The family would like to thank Fr. Timm Holowatch and V. Rev. Alexey Karlgut for their love, support and friendship over the years. Funeral services will be held Wednesday, 11:30 am at Ss. Peter and Paul Russian Orthodox Church 210 Hill Ave. Endicott, NY. Burial will be in the Parish Cemetery. The family will receive friends at the church on Wednesday from 10:30 am until time of service at 11:30 am. At Stephen's request, in lieu of cards and flowers, please consider a donation in his memory instead to Ss. Peter and Paul R.O. Church, which meant so much to him.
