About Our Firm

In January 2026, DePanfilis & Vallerie became Of Counsel to and joined the full-service law firm Mandelbaum Barrett PC, expanding its capabilities and offerings. The same attorneys you have known for the past forty years are now backed by an experienced support staff and deeper bench and they continue to pursue the vision of the firm’s founders by providing legal advice and counsel in a number of practice areas.

The firm is divided into separate practice groups that are specifically tailored to the expertise of the lawyer and the individual needs of each client. As a result of this compartmentalized approach to providing legal services, clients receive the individual attention and legal skills their particular situation deserves.

Under the careful stewardship of Hon. Anthony DePanfilis, each practice group is closely monitored for quality to ensure that all of our clients receive the personalized attention that has become a proud hallmark of DePanfilis & Vallerie, LLC and of Mandelbaum Barrett PC.
