Jim Dean Law Professional Corporation is a criminal law and wills and estates firm in London, Ontario, founded in 2011 by James (Jim) E. Dean, a Barrister, Solicitor and Notary Public. Dean spent two decades as a police officer with the London Police Service, earning a Bachelor of Law degree from Western University in 2010 before leaving the force to practice law. That policing background included work as an expert witness in narcotics matters, a crisis negotiator, a breath technician in impaired driving cases, and a collision reconstructionist, experience that now feeds directly into the firm's criminal defence work.
The firm has grown from a solo practice into a team of three lawyers and a senior law clerk. Chris Marquis earned a law degree at the University of Leicester in the UK, competing for the university in national and international legal competitions, then spent three years as a court clerk and assistant trial coordinator at the London courthouse before joining Jim Dean Law. Victoria Heppenheimer grew up in London, studied criminology at Carleton University, volunteered with the John Howard Society's bail supervision program, and completed a Juris Doctor at the University of Ottawa. Senior law clerk Tammy Courage rounds out the team. Alongside its own clients, the firm also reviews expert reports, search warrants, statements, and recorded interviews for other lawyers and professionals.
James Dean serves on multiple non-profit boards in the London community.
Jim Dean Law is one of the partner firms of the Hamilton Road Legal Centre, a community legal hub that describes itself as committed to access to legal services for everyone in the surrounding area, regardless of financial ability.
