6 Brands Endorsed By John Isner

John Isner has one of the most powerful serves in the game of tennis.  Part of the reason is that he is 6 ft 10 inches and is one of the tallest players on the tour.  Until 14, Isner played basketball before switching to tennis in a serious way.

Isner played college tennis at the University of Georgia (2004-07).  He reached the NCAA singles final and won doubles & team titles in 2007. He only started playing on ATP tour after college.

His best grand slam success came at the 2018 Wimbledon Championships, where he reached the semifinals. He achieved a peak singles ranking of world number 8 in 2018. His sponsors are Fila, Prince, Tamko, Defy, Bass Pro, Ebix, Nulo, and Runa. He has earned over $25 million.

TAMKO Building Products is one of the America’s largest manufacturers of residential and commercial roofing products.  John Isner’s father was a building contractor in North Carolina and was a frequent customer of Tamko.  In addition, Tamko’s CEO David Humphreys is an avid supporter of tennis.
