John definitely left his mark on this world, positively impacting anyone who had the pleasure of meeting him. He exemplifies the terms community and compassion for all humanity. Whether he knew you or not he was the first to offer up a helping hand. Many in his life looked up to him as a role model and mentor.

Born and raised in Philadelphia, PA, John has resided in Glen Mills for the past 2 years. He previously resided in Drexel Hill for 28 years where he was an active member of St. Andrew's Parish serving as Collection Counter.
