A former gymnastics coach who taught in Suffern, Hillburn and Stony Point will spend the next four years in prison after pleading guilty to a single charge of sexually abusing his young students. That’s according to News 12, which reports 68 year-old Joseph Lewin of Port Chester was arrested in May 2018 after five of his former students came forward with their stories of abuse. Lewin will also have to register as a sex offender.
