Silent Witness PA is headed by Alanna Berger and Blaise Liffick. This husband and wife team has led the organization since the summer of 2005, when they gathered more than 130 volunteers as Silent Witnesses for the Harrisburg (PA) PrideFest. They have since trained more than 600 Silent Witnesses around the central PA region - including Harrisburg, York, Lancaster, Reading, Allentown, Kutztown, Millersville, and Shippensburg - and as far away as Charlotte, NC.

Executive Director Alanna Berger is a former systems analyst who quit her high-paying (and high-stress!) job in the fall of 2007 to devote herself to this work. She has led her church's Rainbow EqUUality Advocates lay-led ministry for several years, working on behalf of the GLBTQ community. She is a former Board member of the Unitarian Universalist Pennsylvania Legislative Advocacy Network (UUPLAN), which is currently keeping track of state legislation impacting the GLBTQ community and lobbying on their behalf. She was Vice President of the Harrisburg PrideFest Board in 2008-2009. In the Spring of 2012 Alanna was invited to teach a course on Gender and Sexuality Minority Issues at Lebanon Valley College.

Dr. Blaise Liffick (Director of Operations) is a computer scientist at Millersville University, where he has been on the faculty for over 30 years. His office is a designated "Safe Zone" for GLBTQ students, and he is the faculty advisor for MU's gay-straight alliance. He has been involved with the GLBTQ community with his wife for several years, and has been on the advisory committee for the Lancaster chapter of Common Roads (a GLBTQ youth program headquartered in Harrisburg). He also assisted with the planning of the Pride celebration in Lancaster, PA in 2008. Currently he is on the Executive Committee of the PASSHE LGBTQIA Consortium, an organization of the 14 universities of the PA State System of Higher Education offering support, education, and advocacy related to issues of sexual orientation, gender identity, and gender expression. He is also the chairperson of the Millersville University LGBTQIA Committee and the lead Safe Zone trainer.

The couple does not have any GLBTQ children, siblings, or parents, but does this work simply because it's the right thing to do.
