Since 2009 Mark Sullivan’s practice has been devoted primarily to the defense of lawyers at all levels of state and federal courts, and administrative proceedings. Those representations have included professional negligence and breach-of-fiduciary-duty suits, defamation claims, bar grievances, and representations regarding fee disputes, disqualification attempts, and significant sanctions.
Mark’s work for attorneys is not limited to litigation, but also includes prospectively advising attorney clients on ethical issues and general risk mitigation, such as emerging trends in lawyer liability like e-discovery and cyber-liability.
Mark routinely speaks and writes on topics related to lawyer’s liability, and was the one of the primary organizers for all three years of the Florida Lawyers’ Professional Liability Seminar with University of Miami and other Florida firms that focus on lawyer liability. He is active in the national malpractice defense community, and has spoken at the American Bar Association’s national legal-malpractice conference.
Mark earned his Juris Doctor, with honors, from the University of Texas School of Law, and his B.A. in English Literature with minor in Russian Language from the University of Tennessee. While in law school he was an associate editor and notes editor for The Review of Litigation, and was awarded the Dean’s Achievement Award in Mass Media Law.
Mark was also deployed to Guantanamo Bay, Cuba from February to December of 2002 while a reservist in the United States Marine Corps, and previously distinguished himself by graduating first in his class of approximately 200 Marines at the Marine Corps School of Infantry in 1999.
