The Exception That May Swallow the Rule: Williams v. Illinois and the state of the Confrontation Clause​ (The Vindicator, Magazine of the Ohio Association of Criminal Defense Lawyers). 


Mark represents individuals facing felony and misdemeanor charges in courts throughout Ohio. Whether your case is in a court of common pleas, a municipal court, or a mayor's court, Mark has likely appeared before that judge and dealt with that prosecutor. He's argued criminal cases before the Eighth District Court of Appeals and the Ninth District Court of Appeals.

Prior to forming his own practice, Mark was an Associate Attorney with Zukerman, Daiker & Lear Co., LPA, one of Ohio's leading criminal defense firms. While at ZDL, Mark represented clients charged with a wide variety of crimes. He won the dismissal of a client's felony count of Aggravated Vehicular Assault based on Double Jeopardy violations, resulting in a sentence of probation rather than the five years in prison sought by the prosecutor.

Before working as a defense attorney, Mark served as a Post Graduate Fellow in the Cleveland Prosecutor's Office, representing the City in criminal prosecutions. He tried cases, negotiated over one thousand plea bargains, and authored several appellate briefs. 

As a Law Clerk with the Legal Aid Society of Cleveland's Education Unit, Mark defended students facing expulsion and suspension from school and helped enforce state and federal protections for special-needs children.

Mark worked closely with federal prosecutors as a Law Clerk at the United States Attorney's Office, assisting with trial preparation for the successful prosecution of a defendant who set the most deadly house-fire in Cleveland history.

He currently serves as Court-Appointed Counsel in municipal and common pleas courts throughout Cuyahoga, Lorain, and Medina Counties.
