Keith was born and raised in Salisbury, Maryland. He earned his law degree in 2015 from the University of Baltimore School of Law, and has an undergraduate degree from Towson University.

Prior to law school, Keith worked as a law clerk with the Office of the Public Defender in Wicomico County. This time at the public defender’s office inspired him to be a criminal defense attorney, and his passion for criminal defense work lead him to obtain the highest grades in his class for Constitutional Law and Constitutional Criminal Procedure while in law school. During law school, Keith interned with the Honorable Sally D. Adkins of the Court of Appeals of Maryland, the Baltimore City State’s Attorney’s Office, and worked with Professor Bryon L. Warnken to update and revise Professor Warnken’s treatise Maryland Criminal Procedure. After graduating with honors from law school, Keith clerked for the Honorable Michael J. Finifter for the Circuit Court of Baltimore County.
