The McMahon/Ryan Child Advocacy Site, located in downtown Syracuse, is Onondaga County’s Child Advocacy Center.

It is a non-profit organization established to honor the ideals of members of the McMahon/Ryan families and provide support to existing community efforts that address child abuse.

Beginning in 1998, members of the McMahon and Ryan families began working with several community organizations that address child abuse in Syracuse to create one place where children who have been abused and their non-offending family can come for investigative, medical, therapeutic and support services.

McMahon Ryan Child Advocacy Site is housed in an 1860's vintage federalist style house that was totally renovated by many volunteers.  Local businesses and corporations donated dollars, in kind donations and skilled labor to complete the renovations.  .  The agency incorporated in December 1998 and opened the doors to offer services to the community in April 2002.
