In 2003, her responsibilities expanded as she became the Clinical Coordinator for Building Blocks.  As a result of NY State Plan Amendment #09-61of 2009 requiring compliance with all laws and regulations related to the receipt of federal participation in the School Supportive Health Services Program, Building Blocks developed a Corporate Compliance program and Ms. Aversano assumed the role of Corporate Compliance Officer.
