Our Team

In 1977, Rhodie Mercer, Gordon MacNab, and James Vavasour founded the law firm of Mercer MacNab and Vavasour by combining their practices with the practice of Isaac Mercer, Q.C. The intention of the partners was to establish a diversified legal practice to provide a broad range of legal services to its clients, concentrating on Real Estate, Family Law, Estate Planning and Administration, Corporate and Commercial, Personal Injury, and Civil Litigation.


Anne M. Fagan joined the firm in 1986 upon the retirement of Isaac Mercer, Q.C. Sheilagh M. Murphy joined us in 2017. This further enhanced the ability of the firm to expand its client base.


Building upon the solid foundation established in 1977, MacNab Fagan & Murphy continues to provide reliable professional legal services to our wide range of clients. In keeping with the desire to offer cost-effective and efficient professional services with a personal touch, we elected to remain small in terms of numbers. With our 136 years of combined experience, we continue to attract a wide range of clients. Our extensive practice now includes most legal areas including Real Estate, Family Law, Estate Planning and Administration, Corporate and Commercial, Personal Injury, and Civic Litigation. In addition, we are proud to offer Alternative Dispute Resolution Arbitration and Mediation Services.


R.A. Gordon MacNab, Q.C., Anne M. Fagan, Q.C., and Sheilagh M. Murphy, Q.C., are all members in good standing with the Law Society of Newfoundland and Labrador and members of the Canadian Bar Association. The firm is a Member of the St. John’s Board of Trade Business.
