Mark Nicholson is the founder of the Law Office of Mark Nicholson in Indianapolis, Indiana. He specializes in criminal defense, personal injury, and civil rights law.

A U.S. Army combat veteran, Nicholson earned his Juris Doctor from Indiana University Robert H. McKinney School of Law in 2008 and has been serving clients in Indiana since 2009.

Before starting his private practice, Nicholson held various public service roles, including deputy public defender with the Indiana State Public Defender Office and the Marion County Public Defender Agency, where he also supervised and trained other attorneys. He has also taught as an adjunct professor at Indiana University’s McKinney School of Law and served as a Judge Pro Tem for the Marion County Superior Courts.

Nicholson’s legal focus includes defending individuals accused of crimes, representing victims in personal injury cases, and pursuing civil rights claims related to police misconduct and illegal arrests.

His personal journey is quite unusual—after military service, Nicholson was convicted of voluntary manslaughter, spent over a decade in prison, and later rebuilt his life through education and advocacy before becoming a lawyer. Today, he writes and speaks about civil rights and the criminal justice system, including authoring the book The Law: From Prison to the Street.
