About Me

David Hamel was born in Oklahoma City and spent much of his childhood all over the United States.  In 1997, he returned to his home state of Oklahoma, and lives in Oklahoma City.  Prior to entering the legal practice, David served in the United States Marine Corps where he served a tour of duty in Iraq .   David received a B.A. in Political Science with an emphasis in International Relations from Oklahoma State University.

                Upon graduation, David attended Oklahoma City University, where he earned his Juris Doctorate Degree and a Master’s Degree in Business Administration.  While in law school, Mr. Hamel was very active in student organizations and was the President of the Second Amendment Shooting Club, an organization dedicated to educating the public about firearms and hosting shooting sport events.

                Mr. Hamel sparked an interest in firearms law and criminal defense while in law school and earned the CALI award for Firearms Law and Policy, an honor reserved for the top student in a course.  Additionally, he received the Dean’s Fellowship and interned at the Oklahoma County Public Defender’s Office where he aided in the representation of individuals charged with misdemeanor and felony offenses.  Mr. Hamel also interned for Robert A. Manchester III where he ultimately became an associate upon being sworn in and licensed by the Oklahoma Bar Association.  While working for Mr. Manchester, Mr. Hamel refined his skill set by representing and/or aided in the representation of municipal, state, and federal crimes, as well as civil litigation.
