CSG Law’s Giantomasi, Toft and Mathews Named to 2025 NJBIZ Law Power List
Chiesa Shahinian & Giantomasi PC (“CSG Law”) is pleased to announce that Francis J. Giantomasi, Co-Chair of the firm’s Executive Committee, Marie L. Mathews, Managing Member, and Dennis M. Toft, Chair of the Environmental Law Group, were named to NJBIZ’s 2025 Law Power list, which recognizes New Jersey’s most influential attorneys in private practice, public service, corporate law departments and nonprofit organizations.
Frank Giantomasi has been a pillar among the NJBIZ Law Power list for more than five years, and he was once again recognized in this year’s NJBIZ Power 100 list. This is the third appearance in NJBIZ’s Law Power list for Dennis Toft, and the first time Marie Mathews was named to the list. Marie was also named to NJBIZ’s 2025 Power 100 list earlier this year.
NJBIZ praised Giantomasi as “one of the state’s leading real estate attorneys,” noting his prominent work throughout the years.
“Giantomasi brings more than four decades of experience to the table across all aspects of real estate acquisitions, sales, development, complex commercial transactions and Chancery litigation – having successfully argued before intermediate appellate courts and New Jersey Supreme Court,” said NJBIZ. “He has served as chief development counsel on a number of high-profile real estate projects – including the planning and development of Prudential Financial Inc.’s HQ, Panasonic North America’s base and Lionsgate Newark Studios in Newark, as well as Netflix Studios at Fort Monmouth.”
The publication continued: “He is widely recognized as a regional leader in planning, zoning and development law including tax abatement law – and has been one of the driving forces behind CSG Law’s continued growth. In addition to being a regular on lists such as these across the business and legal ecosystem, Giantomasi also continues to serve as chairman of the board of trustees for Newark Beth Israel Hospital.”
NJBIZ recognized Mathews for her efforts, including her new role as Managing Member.
“Mathews is the managing member at CSG Law, succeeding Patricia Costello earlier this year,” said NJBIZ. “She previously served in a variety of management positions at CSG Law, including as practice group leader of the litigation group and deputy general counsel to the firm. Her background also includes representing an array of clients in complex commercial litigation matters throughout the region.”
“As managing member, Matthews oversees the firm’s 200 attorneys and 150 other professionals,” the publication said. “The team is assigned to the firm’s headquarters as well as its rapidly growing location in midtown Manhattan. Outside of the firm, Mathews serves as the president of the Greater Newark Holiday Fund. The charity has contributed more than $12 million over the years toward the betterment of thousands of families across the state. Earlier this year, Mathews was named as a recipient of a 2025 NJBIZ Leading Women in Business award, which will be presented at a ceremony in August.”
For Toft, the publication emphasized his widespread experience and influence in environmental law.
“As chair of the environmental law group at Roseland-based CSG Law, Toft provides counsel on all aspects of environmental law, including regulatory counseling, environmental due diligence, permitting, enforcement and environmental litigation, development/redevelopment and environmental insurance,” said NJBIZ. “He regularly appears before the New Jersey Department of Environmental Protection, the Army Corps of Engineers, the U.S. Environmental Protection Agency, municipal land use boards, the Office of Administrative Law, and in state and federal courts.”
The publication continued: “Toft has also earned numerous accolades, including an icon award from NJBIZ in 2019. He was also included on the 2021 Leaders in Law list and Law Power 50 compilations in 2022, 2023 and 2024. Additionally, Toft is a trustee at the New Jersey Institute of Technology and environment/energy initiative chair of the New Jersey Chamber of Commerce’s executive committee, as well as frequently tapped by the media to speak as a subject matter expert on environmental issues.”
