Jason Frierson joined Cornerstone in February 2025 following his service as the United States Attorney for the District of Nevada since 2022. He was nominated by President Biden, acting as the Chief Federal Law Enforcement Officer for the District of Nevada, and the first African American to hold the position. In this role, Jason led a team of more than 100 prosecutors and staff professionals, including 55 attorneys who handled federal criminal, civil and appellate cases. In addition, he met regularly with local, state and federal law enforcement agency leaders, and other key community leaders and organizations to discuss investigations, current cases and developing trends.

Jason started his career representing the indigent, serving as a prosecutor of white-collar criminals and as an agency attorney in protecting child abuse victims. In 2010, he was elected to the Nevada State Assembly and was voted the best freshman Assemblyman in 2011. After being re-elected for the 2013 session, he served as Chairman of the Judiciary Committee.

After one term out of the legislature, Jason was elected to return to the Nevada Assembly in 2016 and was then selected in a bipartisan and unanimous vote to serve as the Assembly's first African American Speaker in Nevada history. He served in that role for three consecutive legislative sessions, leading one of the most diverse state legislatures in the country and the first female majority legislature in the country's history.

Prior to his legislative service, Jason served in a variety of significant legal roles in both the public and private sector. Jason holds a B.S. in Health Science from the University of Nevada and earned his Juris Doctorate from William S. Boyd School of Law, University of Nevada, Las Vegas.
