About Tom
Tom began his journey working with individuals with disabilities in 2013 when his Father, whom also works for the same cause with RSC, told him how rewarding the work was. Tom took a position as a Graveyard at one of the Group Home sites but quickly discovered that the more he got to know the individuals he was serving, the more he wanted to do to help them succeed. He has enjoyed taking different positions that help him engage, assist, and motivate our individuals served. When not working for our individuals you can find Tom traveling and experiencing new places & activities with his family and dog.
