Snyder’s career reflects a steady trajectory from law school to an established practice in the Philadelphia-area legal community. She balances courtroom work with client counseling and seeks practical resolutions when the facts and law allow. She currently focuses her practice on criminal defense matters in Pennsylvania and New Jersey.
