Mark Yocum

Mark was born and raised in Casper, and grew up with strong ties to Cheyenne, spending much time here visiting his grandparents. He grew up hunting and fishing Wyoming and is passionate about elk hunting in Wyoming to this day. He graduated from Natrona County High School in 1996, and then from the University of Wyoming at Casper College with a bachelor’s degree in criminal justice in 2001. He began a career as a Wyoming Peace Officer with the Wheatland Police Department in 2000. After a few years there, he moved to Sheridan and served two years as a Deputy Sheriff. He finished his law enforcement career after moving to Cheyenne with his wife, Rachel, where he finished out a 20-year career as a Deputy Sheriff.

By the time Mark retired from law enforcement in 2020, he had experienced a revelation that he would be better able to serve people and uphold the Wyoming and United States Constitutions if he attended law school. He is passionate about ensuring that people’s rights are protected and can use his past experience to effectively represent people accused of a crime.

He graduated from the University of Wyoming, College of Law with his Juris Doctorate with Honor in 2023. While at law school, Mark worked in the Defender Aid Clinic where he learned how to become a criminal defense attorney. He also completed an externship, working for Chief Justice Fox of the Wyoming Supreme Court in his third year of law school, where he learned a great deal about the law from the finest legal minds in Wyoming.

Mark married the love of his life, Rachel, in 2003, and they have four wonderful daughters. Mark enjoys teaching his daughters to hunt elk and loves camping with his family. He can also be found at a wide variety of his daughter’s extracurricular activities, such as softball, marching band performances, basketball, and music recitals.
