Kim Herring

Owner, Trinity Sports Performance - Personal Trainer - Sports Performance Coach

Kim Herring former 9 yr. NFL player, is considered to be one of the best defensive backs to come out of Penn State. Coach Herring specializes in resistance speed and agility training for ALL sports, strength and conditioning and defensive skills development.

Coach Herring is a 1993 graduate of Solon high school in Cleveland, Ohio. During that time, Kim was a record setting tailback and kick returner who was a 2-time big school 1st team all-state, all-american and rated the #1 running back in Ohio upon his graduation.

Upon receiving multiple scholarship offers, Kim decided to play for Joe Paterno at Penn State University majoring in Nutritional Science. Entering his sophomore year he was switched to defense and ended up becoming the starting free safety on the 1994 undefeated Rose Bowl winning team. Kim would ultimately become a three year starter at free safety, team captain, 1st team All-American and All- Big Ten in 1996. He would leave Penn State as the #4 career interception leader in school history with 13.

Kim would be drafted in the 2nd round of the NFL draft (#58) to the Baltimore Ravens. He was the starting strong safety on what many consider to be one of the best defenses in NFL history; the Super Bowl XXXV champion Baltimore Ravens, collecting a interception in the game.

Kim parlayed his Super bowl success into a free agency opportunity to join the St. Louis Rams; and once again he was back in the big game as the starting free safety on the Super Bowl XXXVI team that eventually lost to the N.E. Patriots.

Throughout his 9 year career, Kim played defense alongside many great players as well as Future Hall of Famers Ray Lewis, Rod Woodson, and Aeneus Williams, as well as legendary defensive mind Marvin Lewis.
