She is qualified under the rules of criminal procedure to handle death penalty cases. Ms. Snyder treats cases in the appeals stages with the same energy and attention to detail as her trials.

In addition to Criminal Law, Ms. Snyder’s areas of concentration include Special Education Law and Election Law. She has represented individuals, families, and the School District of Philadelphia in Special Education matters.

Recently, Ms. Snyder represented Hillary for America (campaign for Democratic candidate for President of the United States, Hillary Rodham Clinton) and Krasner for DA (campaign for the Democratic candidate for Philadelphia District Attorney, Larry Krasner) in Election Law matters.
