Mark Sullivan is a partner at Klein Glasser Park & Lowe, where his practice since 2009 has been devoted primarily to the defense of lawyers at the trial and appellate level of state and federal courts, as well as administrative proceedings. Those representations have included professional negligence and breach of fiduciary suits, defamation claims, bar grievances, and representations regarding fee disputes, disqualification attempts, and significant sanctions.

Mark’s work for attorney clients is not limited to defending lawsuits, but also includes prospectively advising attorney clients on ethical issues and general risk mitigation, including emerging trends in lawyer liability such as e-discovery and cyber-liability. Mark regularly attends the American Bar Association’s Legal Malpractice Conference to stay abreast of emerging trends in the practice area, and has lectured on legal malpractice issues.

In addition to lawyer professional liability Mark also handles commercial litigation, FDCPA and FDUTPA claims, and defamation defense for individuals and businesses.

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.
