Contributing to our community is at the forefront of who we are and how we practice law as we live out our values.

For us, being responsible corporate citizens influences how we choose our suppliers (we choose local as much as possible) and the environmental impact that we have within our greater world. We also regularly give back with our time and financial contributions.

Our history

Sullivan Law Ptbo is very proud that it is and will be continuing a legal tradition that began on or about the 1950s with the Honourable Justice Richard Batten and continued with Mr. William Davidson.

Mrs. Lois Davidson then joined Mr. Davidson in his practice. Mrs. Davidson, many believe, was the first female lawyer in Peterborough. Her dedication to the legal community and particularly to the law library caused for it to be named in her honour the ‘Lois C. Davidson Law Library’. Lois continues to be a great supporter and friend of our office.

After Mr. Davidson’s sudden passing, Mr. Scott McMichael joined Lois and McMichael Davidson was created. Mr. McMichael has been carrying on this practice since Mrs. Davidson’s retirement in 2003. On January 1, 2018 Scott McMichael officially transitioned his practice to Sullivan Law Ptbo.

Fred Gariepy and Sharon Murphy were the force behind Gariepy Murphy, which began (where Sullivan Law was located on Sherbrooke Street) in 1984. Their practice grew greatly over the years both from Fred and Sharon’s legal skills and their kind and personable approach with their clients. Fred continued their practice until 2020 when he fully retired and transitioned their practice to Sullivan Law.

In October 2023, Sullivan Law moved to 362 Queen Street to a space that better fits our clients’ needs. Our space is now much more accessible and facilitates mediation sessions in a welcoming environment.
