Owners and boxing coaches, the Giovanis brothers opened 15th Round Boxing in December of 2015. 


The brothers were born in Rhode Island. By the age of 13 they joined Rhode Island Boxing, home of five time world champion Vinny Paz. Over the years, both brothers competed in amateur boxing matches and smokers where they refined their skills as boxers. 


At the age of twenty one, the brothers moved to Florida where they continued to train at St. Pete Boxing Club in Florida, home of the IBF champions Ronald “Winky” Wright & Jeff “Left Hook” Lacy.


Wanting to grow even more in the martial arts, George also learned Muay Thai, (Dutch style) which is perfect for self defense and MMA, as it originates in a boxing stance.


In 2013, George and Evangelos moved to Los Angeles and worked at various fight clubs where they trained kids and adults how to box. During the next few years, the Giovanis bros trained dozens of fighters that became champions, winning belts in the PAL Adidas National Tournament, the Blue & Gold Tournaments and the So. Cal State Championships. They also coach and manage several professional, undefeated fighters.


In 2018, 15th Round Boxing expanded into East Pasadena, adding a second location and helping spread their boxing culture.

The Giovanis brothers also produce/direct feature films. Their latest effort BEREAVE starring Malcolm McDowell, Golden Globe Winner Jane Seymour, Oscar Winner Keith Carradine and Mike Starr, along with a stellar supporting cast, screened at over 22 film festivals and won 13 awards. The film is scheduled to be released via Sony and Archstone distribution.




Retired and legendary boxer, David Nganga Kamau was born August 4, 1965 in Nakuru, Kenya. Kamau competed in the 1988 Summer Olympics in Seoul, in the Light Welterweight Division where he won his first two bouts to advance to the third round. He was recruited from Africa by Don King to compete as a professional boxer in the USA. Kamau had his professional debut in 1990, and although considered a late start for boxing (at the age of twenty five), went on to amass an impressive list of victories with a professional record of 30W-4L-0D with 22 wins coming by KO. His only losses would be to boxing legends, Julio Cesar Chavez (who many feel he beat), Oscar De La Hoya, Antonio Margarito and Danny Perez. David Kamau currently works with the Giovanis brothers and trains boxers with the hopes of making a champion. He is also a bus driver and is a very active member in his church.
