Jennifer Dumin, Esq.

Jennifer Dumin comes to Sadek and Cooper after nearly fifteen years of experience as a family law attorney. For over three years, she has served on the Board of Directors of the Therapy Center of Philadelphia, a community-based mental health non-profit which offers a model of healing that serves hundreds of women, transgender, and gender non-conforming clients each year, attending to their identities and experiences of oppression. 

Jenn has also served the LGBTQ+ community through her work as a mentor for The Attic, an organization which serves LGBTQ+ youth, and as Co-Chair of the Legal Rights of Contemporary Families Committee of the Philadelphia Bar Association.

One of Jenn’s key areas of focus will be serving the LGBTQ+ community. As a proud member of that community, Jenn personally understands the value of working with inter-community professionals. Our mutual goal is ensuring Sadek and Cooper Law Offices remains a place where lesbian, gay, bisexual, transgender, and queer/questioning individuals in Philadelphia and the surrounding counties receive unparalleled services that match their unique legal situations and needs.
