Raised by his mother Gigi and his grandparents, Bernard and Clida Rose, Seth Rose grew up in his grandparents' home where a driving work ethic and desire to help others was instilled in him.

Seth attended the University of South Carolina on a Men's Tennis scholarship where he excelled on and off the tennis court. Through hard work, Seth became one of the top collegiate Singles players in the nation and one of only 10 Gamecocks to ever be selected as an All-American Singles tennis player. In 2014, USC inducted Seth into the Athletic Hall of Fame.

Seth and his wife Anna, a pharmacist, were married in April 2008. They are the proud parents of three children: Cole (age 7), Luke (age 5), and Tillie (age 2). The Rose Family are members of the Downtown Church of Columbia. A graduate of the USC School of Law, Seth is a former prosecutor for Richland County and the founder of Seth Rose, Attorney at Law.

During his first year on Richland County Council, Seth was responsible for the "biggest act of transparency in council history" when he sponsored the motion to publicly record and broadcast council meetings. He followed that measure up with another monumental accomplishment by sponsoring and fighting to have roll-call voting on Council. Before these items were approved, members of county council voted by voice only and there was no record of how individual council members voted on important measures. Taking these advancements in transparency to the next level, Seth Rose sponsored the motion on Nov. 14, 2017 that was approved by a 7-2 vote to have all votes of council recorded electronically.

Seth Rose has also been responsible for: stopping unwanted rock quarries along Bluff Road, near Williams-Brice Stadium and the Arthurtown neighborhood; closing adult businesses operating for decades in violation of county zoning laws; expanding library services across downtown Columbia and St. Andrews; and voting against financially wasteful budget items.

Seth is also known for his exemplary constituent service and has been called a "voice of reason" on County Council by many. Seth was also recognized by Keep the Midlands Beautiful for being the "Green Elected Official of the Year," becoming the first-ever local elected official to win the award.
