Our Team


Christine Simiriglia, MS
President & Chief Executive Officer

Christine Simiriglia established Pathways to Housing PA in Philadelphia in 2008.  Pathways houses and serves approximately 500 people who were chronically homeless, in permanent, scattered site housing. The program has had remarkable results with a population that doesn’t usually see a lot of successes.

In 2014, she launched the Philadelphia Furniture Bank (PFB), providing furnishings to individuals and families moving out of homelessness, believing that no one should sleep on the floor. In 2016 Pathways became the first Housing First program to use a scattered site/harm reduction model to work with people who are street homeless with a substance use disorder, primarily opioids. Also in 2016, Pathways established a medication-assisted treatment program, in house, to fill a treatment gap made larger by the opioid epidemic. In 2017, Pathways developed a Housing First Training Program for agencies and communities looking to use the model. Pathways believes that the best trainers are practitioners and that they can answer questions that no one else can. That training has grown into Housing First University.

For fifteen years prior, Chris was Vice-President at the Mental Health Association of Southeastern Pennsylvania. Previous work included Director of the Outreach Coordination Center at Project H.O.M.E., Assistant Director at the City’s newly formed Office of Services to the Homeless and Adults, and Assistant Director for the Philadelphia Committee for the Homeless.

Chris has spent the last decade traveling throughout the US speaking at conferences and symposiums and providing technical assistance to organizations and communities struggling to establish Housing First programs. She believes that great outcomes are achievable for everyone if providers offer choice, kindness and opportunity to the people they serve.
