Dan Procaccini is a seasoned litigator who clients trust to champion and protect their interests.  Drawing on nearly a decade of diverse experiences, Dan represents businesses and individuals in complex commercial disputes, product liability actions, high-stakes government investigations, and sensitive internal probes. He has advised clients across a wide variety of industries, including healthcare organizations, educational institutions, consumer products manufacturers, and technology companies.  Dan argues regularly in state and federal courts throughout New England, but strives to resolve a client’s concerns without litigation whenever possible.

In the courtroom, Dan is a sharp and respected advocate.  His experience includes acting as first and second chair trial counsel in various courts.  In 2016, Dan served as a special assistant district attorney in Norfolk County, Massachusetts, where he tried more than a dozen cases to verdict.  In 2017, he served as trial counsel with a state-appointed special prosecutor in a high-profile felony criminal prosecution arising out of the in-custody death of a state hospital patient.

Maintaining strong community ties is a core principle of Dan’s practice.  He has provided hundreds of hours of pro bono legal aid for low income, elderly, and disabled clients facing urgent challenges.  In one such action, he achieved statewide reform in Massachusetts by spearheading litigation to eliminate a rule that unfairly denied underprivileged teenagers merit-based aid for higher education.

Prior to joining AP&S, Dan practiced with a national law firm headquartered in Boston.  He also served as a law clerk for the Honorable William E. Smith, Chief Judge of the U.S. District Court for the District of Rhode Island, and the Honorable Francis X. Flaherty, Associate Justice of the Rhode Island Supreme Court.

Dan is also an advocate for the performing arts and serves on the board of directors of Rhode Island’s Wilbury Theatre Group.
