Our History

In 1946, Sister St. Mark McMahon saw the need for special education classes for school-aged children with intellectual and developmental disabilities who were falling through the cracks of the traditional education system.  Sister St. Mark, along with the Sisters of St. Joseph founded Holy Childhood.

The focus was on Education and Vocational Training.  Academic subjects were adapted to each student’s level, pace and ability. This focus remains the same today and a multitude of programs have been added.  In the School Program and the Adult Program, academics and program areas such as Activities of Daily Living, integration in the community through Work-Based Learning, Supported Employment and many other individualized programs continue to help prepare people with intellectual and developmental disabilities for an independent, happy, and fulfilling life.

Over the years we’ve outgrown several different facilities.  The Holy Childhood campus is now located at 100 Groton Parkway., in Henrietta.  We have seen tremendous growth in all areas and have become a multi-faceted, innovative non-profit agency.  Mrs. Donna Dedee is our President and CEO.

Holy Childhood is a non-profit, non-denominational agency, which serves more than 200 people with intellectual and developmental disabilities, in its School Program (ages 5-21) and in its Adult Program, which serves people from age 21 through retirement.  Services include individualized education, vocational training, transition and skills training, supported employment and diagnostic and treatment services.

Holy Childhood is a 2017 ETHIE Award Recipient from the Rochester Area Business Ethics Foundation (RABEF).
