Mark DellaGrotte

Mark portrays himself as a striking coach to fictional character Scott Voss (played by Kevin James) in the 2012 sports comedy film Here Comes the Boom.

Contrary to general belief he has, by his own admission, less than 10 fights, most of which were held in Thailand. He says he has a winning record but admits a few losses one of which was to BOLTON UK Thai-boxer Nigel Green comfortably winning after three rounds in New York. The 30-year-old qualified instructor from Little Lever UK fought at the Big Apple's World Gym in Long Islandand, July 1999.

DellaGrotte was first introduced to Muay Thai in 1997 when he was taken by a friend to the famed Yodtong boxing camp in Pattaya where he lived and trained. After proving his worth as a student and a fighter he was looked favorably upon by Kru Yodtong himself, a famous Muay Thai instructor who also takes in troubled youths. After eight years Kru Yodtong, as he’s known professionally, designated DellaGrotte as his representative in the United States to teach and preserve the art. In honor of his mentor, DellaGrotte named his gym Sityodtong, which means, "Student of Yodtong".

In 1992, his quest for a more combative martial art was complete when he met Guro Guy Chase, who had studied with some of the greatest martial artists of his time. Guro Chase had trained with Dan Inosanto, Ben Lagusa, Herman Suwanda, Ted Lucay, Salam Allsi, Surachai Sirisute and even Karl Gotch.

Mark also has extensive training and is certified in the arts of Kali Escrima, Pencak Silat, Jeet Kune Do, Savate, and Brazilian Jiu-Jitsu.
