John O. Mancini

John O. Mancini


John’s focus over the last 20 years has been on real estate, business, and corporate law, servicing his clients and their needs in a responsive, dedicated and efficient manner. As a result, John has handled some of the largest developments in the State of Rhode Island and litigated case setting precedents in real estate and tax assessment law.

In his practice, John has represented major real estate developers, construction companies and financial institutions in Rhode Island and Massachusetts on such matters as commercial office projects, shopping centers, planned unit and condominium developments (residential and commercial), financing, general and limited partnerships, and joint ventures. John’s business and real estate practice often leads him to address such issues as environmental concerns, title disputes, easements and construction litigation.

Moreover, his knowledge, experience and temperament have been the basis for his appointment on occasions as a Receiver or a Special Master for the purpose of restructuring various entities in real estate and other areas. Recently, John was appointed a Receiver of a failed recycling company and became responsible for overseeing the clean-up of the recycling facility in East Providence, Rhode Island.

John frequently lectures on land use issues and real estate law, and his accomplishments have enabled him to be selected by his peers in “New England Super Lawyers” in 2014, 2015, 2016 and 2017. He has been named as one of the top lawyers in Rhode Island for Business Litigation and Real Estate by the Rhode Island Monthly Magazine for the years 2012, 2014, 2015, 2016 and 2017. John earned his B.A., cum laude, from Boston College and his J.D. from Boston University School of Law, where he remains an active alumnus.

Additionally, John has a leadership role in the firm’s management, responsible for the day-to-day operations, and the firm’s growth plans for the future. His goal at Mancini Carter is to develop attorneys that are competent, compassionate, passionate and professional; ensuring that the client gets practical advice by a knowledgeable, straight forward-thinking attorney.

John’s dedication, responsiveness, hard-working style, knowledge and temperament have been the bench mark of his success and the premises of Mancini Carter’s mission, to ensure that the clients’ needs and issues are professionally and zealously advocated and addressed.

Past Experience

Prior to starting Mancini Carter, PC, John worked as a partner for fifteen (15) years at a Providence based real estate law firm and previously worked as an associate at Edwards & Angell assisting on numerous leasing and acquisition transactions for clients throughout the Northeast, including CVS Corporation and Fleet National Bank.  John started his legal career at Holland & Knight (F/K/A McGovern, Noel & Benik), where he represented numerous developers in respect to the acquisition and development of real estate.

In the community, John has been involved as a local councilman, where he was first elected in 1996 to the Cranston City Council. John served as a city-wide councilman representing 80,000 residents from 1996 to 2002.  As a city-wide councilman, John was the chairman of the finance committee, vice chair of the ordinance committee, and member of the public works and claims committee.  In 2004, John ran for Mayor of Cranston, where he was the Democratic contender.  John gathered thirty (30%) percent of the votes in 2004 and learned that the majority of the residents of the City of Cranston felt he would be a better Attorney than Mayor.

John’s municipal legislative experience is of unique and invaluable benefit to clients as he assists and counsels them through the process of real estate development and agency approval.  Because of his first-hand knowledge, John has ushered numerous residential and commercial client projects through the maze of Rhode Island’s regulatory approval processes.
