Joseph O’Sullivan, Esq., Associate

Attorney Joe O’Sullivan has been with Canner Law & Associates since 2015. Prior to that time he operated his own firm, O’Sullivan Law, P.C., based in North Reading, MA. He focuses on real estate conveyancing and land title matters including all aspects of purchases, sales and refinances, including purchase and sale negotiation, condominium document review, condominium conversions and residential leases.

Joe received his law degree from New England Law | Boston in 2012. While at New England Law | Boston, he founded and served as the President of the American-Irish Law Society, which won the SBA Student Organization of the Year Award in its inaugural year for the work done in conjunction with City Life/Vida Urbana and the Harvard Legal Aid Bureau to fight evictions and preserve communities in the aftermath of the financial crisis, and for the work done to raise food and money for the Greater Boston Food Bank. Joe also took on other leadership roles, including with the Boston Bar Association Pro Bono Committee, Public Interest Law Society, the Constitutional Law Society and the Animal Law Society, as well as working with other groups in furthering common causes.

Joe received his B.S. degree from St. Thomas Aquinas College in Sparkill, NY in 2004. In the time between obtaining his undergraduate degree and attending law school, Joe worked in various capacities with national and multinational corporations, in both operational and sales oriented positions. This experience included two years with residential lenders, allowing him to have a broad understanding of the residential process from different “sides of the table”.


"This was a very smooth transaction. Attorney O'Sullivan helped make this an easy closing. He was knowledgeable, pleasant and professional."

– Margie Roberto – Agent with Boardwalk Real Estate Corp. December 2018.

"Last month I had the pleasure of working with Joe in purchasing a condo on the north shore. Throughout the entire process, Joe was extremely attentive to all details, gave excellent advice, and made himself available for any and all questions. I greatly appreciated the professionalism and look forward to working with Joe on future projects!"

– Brian B. – Buyer – August 2018

“Joe helped my wife and I with the closing on our condo in Cambridge. We found him to be professional and very personable. He walked us through the mire of closing paperwork step by step and took the time to make sure we understood everything to our satisfaction. He was punctual with all appointments and correspondence and made the whole experience very easy. I would highly recommend him to help anyone with the closing of their home.”
