Sullivan Mediations

I have been mediating civil litigation disputes for many years, including personal injury, commercial and employment matters.

I have been a member of the Ontario Bar for 32 years. I am a Past President of the Hamilton Law Association and a former Regional Bencher of The Law Society of Upper Canada. I was born and raised in Hamilton and called to the Bar in 1984. I became a Certified Specialist in Civil Litigation in 1992.

I have been trusted by plaintiffs and defendants and their counsel for over 30 years in litigation and mediation matters.

I have co-chaired two of Hamilton’s main continuing legal education conferences for over 15 years.

I fully engage in the mediation process, coupling knowledge of the law until we reach a mutually beneficial settlement.

Complex multi-party mediations are a specialty.

Counsel from all over Ontario have requested that I mediate their cases, from Ottawa to Windsor and to the north.

Having litigated cases from both sides of the Bar, I can communicate clearly the risks of litigation and the rewards of a mediated settlement.
