Miriam S. Edelstein

Miriam S. Edelstein is a Partner with Costello, Mains & Silverman, LLC and represents individuals in employment and civil rights litigation across New Jersey and in southeastern Pennsylvania. 

Miriam has focused on employment and civil rights law since she first began practicing in 2006, with her experience running the gamut from harassment, discrimination and retaliation claims, including whistleblower claims, to both individual and collective/class wage and hour actions. 

Prior to joining the firm, Miriam practiced management-side Labor & Employment law and provided Human Resources counseling for over a dozen years at an AmLaw 100 firm as well as for a premier insurance carrier. During that time, Miriam also provided pro bono counsel to non-profit, charitable organizations, including Lambda Legal Defense & Education Fund, the nation's oldest and largest non-profit focused on the advancement of rights and protections for LGBTQ+ individuals. Miriam stepped away from private practice to join Lambda Legal full-time at its New York City headquarters as its Director of Strategic Partner Programs, working with the organization’s corporate sponsors to improve programs, policies and training to enhance their diversity, equity and inclusion (“DE&I”) efforts. 

After returning to private practice, Miriam began advocating directly for plaintiffs when she joined Costello, Mains & Silverman, LLC in 2020. Drawing on more than a decade of prior legal practice representing companies and organizations across industries and sectors, ranging in size from small, start-ups to multinational, Fortune 20 corporations, Miriam's deep, substantive knowledge of employment and civil rights laws is rounded out by her practical knowledge of how employers and companies operate.

Outside of her practice, Miriam is highly committed to her volunteer work. She serves as an attorney-member of the New Jersey Supreme Court District Ethics Committee for District IIIB, and is on the Board of Governors for the New Jersey Association for Justice (“NJAJ”), where she is also a Co-Chair of the Diversity, Equity & Inclusion Committee, a member of the Education Committee and Women Trial Lawyers’ Caucus, as well as works on amicus curiae briefs for NJAJ on cases pending before the New Jersey Supreme Court. She regularly organizes and presents CLE seminars focusing on substantive and procedural legal topics in employment law, civil litigation as well as DE&I topics, and has authored several articles for legal and business publications on these topics. Miriam is also a member of the New Jersey State Bar Association, the National LGBTQ+ Bar and a former Commissioner of the American Bar Association's Sexual Orientation and Gender Identity Commission. 

Adjacent to her work within the legal profession, Miriam is most passionate about her outreach efforts to increase DE&I in the profession and among the future policy-makers and public in general by guest lecturing for students at Temple University on civics, workers' rights and civil rights.
