Mary Bier
Mary has been providing prevention services in Jefferson Union High School District since 2005 when an alcohol related accident took the lives of two Pacifica teenagers, one who was her nephew Jonathan. Her passion for this work has led to numerous grant funded programs and coalition based community work. She is most proud of all the work accomplished by the youth sector of the coalition: Be the Change Youth coalition (BTC). She has recently partnered with DCYHC to expand alcohol and other drug services (AOD) to include opportunities for youth to address their substance use in a holistic and restorative model. A new program focusing on youth civic engagement will create a path for youth to participate in health equity campaigns and participate on local boards and commissions. Mary is very excited to be part of the team at DCYHC!
