Clients rate this firm highly on Google.
Sullivan Law Ptbo is a law firm in downtown Peterborough, Ontario, handling family law, real estate, wills and estates, business and corporate law, notarial services, and private mediation. Martha Sullivan founded the firm in April 2017. The practice grew through two mergers: McMichael Davidson, a firm with roots in Peterborough going back to the 1950s, merged in during January 2018, and Gariepy Murphy, founded in 1984 by Fred Gariepy and Sharon Murphy, transitioned its practice to Sullivan Law Ptbo in January 2021. The firm moved into its current building at 362 Queen Street in October 2023, a move it made to improve accessibility for clients.
In 2024, Sullivan Law Ptbo became a Certified B Corporation, scoring 102 points on the B Impact Assessment, well above the 80 point minimum. The firm's site says the score is the highest of any law firm in Canada. It was the sixth law firm in the country, and the second in Ontario, to earn the certification. The firm says it's directing 1% of its profits to community giving and paying staff above a living wage. Beyond its core practice areas, it also takes on guardianship, trustee, and personal care coordinator work, for older adults and families managing estate and care decisions.
