She is involved with the New Jersey alumnae chapter as the philanthropy chair. Marissa also interned with PSEG Institute of Sustainability Studies as part of a project with NJ TRANSIT on the allocation of grant funding for a sustainable electric vehicle bus fleet.

At PMT Marissa has had the opportunity to be involved in cases in a multitude of practice areas. She now focuses on cases regarding automobile accidents, personal injury, dram shop liability, environmental & toxic torts, and general liability.
