Ngathao started training in Muay Thai at the age of 11 at the Por.Pinprapha camp in the Rayong province. He had his first fights in various festivals under the name Ngathao Sit Hussein. He later joined the Kiatprachachai camp where he would receive the ring name to Ngathao Attharungroj, from there he had over 60 fights in the various eastern provinces of Thailand. At the age of 16 Ngathao started to compete in Bangkok for the Onesongchai promotion.
Ngathao defeated many notable champions of his era such as Sod Looknongyangtoy, Nongbee Kiatyongyut, Phet-Ek Sitjaopho, Saenchernglek Jirakriengkrai, Wuttidet Lukprabat and Phetek Kiatyongyut. Ngathao captured the most important title of his career on September 30, 2003, when he defeated Petchmanee Petchsupapan by decision to take his Lumpinee Stadium Bantamweight title. Known for his fan friendly, aggressive style, Ngathao earned two "Lumpinee Stadium Fight of the Year" awards in 2003 and 2004.
After retiring from competition Ngathao became a trainer. He teaches at the Por.Khonsong Gym in the Rayong province.
