Melissa Andrieux, Partner and Chief Development Officer at Dorf Nelson & Zauderer LLP, was recently a featured speaker on a virtual panel titled "Justice in Action – A Day Behind the Desk of a Lawyer."

The panel, moderated by Hon. Tanya Kennedy, was held as part of Justice Kennedy’s "Exploring Careers in Law" course through Columbia University School of Professional Studies' Pre-College Programs.

The event gave Melissa the chance to share insights into her role and responsibilities at DNZ while engaging with a classroom of aspiring legal professionals as they prepare to launch their careers. Drawing on her experience across many multifaceted roles, Melissa spoke with confidence and offered thoughtful answers to the students' questions.

We hope her insight offered encouragement to those just starting out on their own paths, and we are grateful to have been part of such a meaningful conversation.

Partner Mark C. Zauderer was an invited guest speaker at the National Bar Association, Inc.'s 101st Annual Convention, where he participated in the Solutions Lab session "Taking Down Corrupt Power," a discussion examining the challenges of maintaining trust in our systems of government.

Mark's remarks addressed the roles and responsibilities of all three branches of government, with particular focus on the legislative branch: the strength of existing laws, the effectiveness of oversight mechanisms, and the extent to which institutions are equipped, and willing, to hold themselves accountable. A standout quote from Mark’s discission: “The rule of law depends not only on the decisions institutions make, but on their willingness to critically examine their own practices in service of greater accountability”.

This conversation was a reminder that accountability does not happen on its own. It requires active engagement. Whether through legislative advocacy, institutional oversight work, or simply raising these questions within our own practices, the legal profession has a role to play in strengthening public trust.

Thank you to the to the National Bar Association for creating a forum for thoughtful discussion on these important topics.

Dorf Nelson & Zauderer LLP team members, Jon A. Dorf, Jonathan Nelson, Mark Zauderer, Melissa Andrieux, and Bernadette Silverstein attended the National Bar Association’s 101st Annual Convention in Nashville, Tennessee. This year's theme, "The Rhythm of Excellence: The Power of Promise, The Energy of Now," perfectly captured what it means to be part of the National Bar Association, and the legal profession in general.

From CLE sessions and leadership forums to meaningful networking with members of the bench and bar, this year's convention was filled with opportunities to learn, grow, and connect. We were inspired by the vast wealth of knowledge shared through these powerful conversations, reminding us at DNZ that our community is stronger when we support and show up for one another.
