SAMPSON LEWKOWICZ

As a young boy in Montevideo, Uruguay, Sampson Lewkowicz discovered a great passion for the sport of boxing.

So much so that he even had a brief amateur career consisting of three fights held at the local YMCA, compiling a 2-1 record. His sole defeat came via knockout “I went flying out of the ring and at that point I discovered that my future was not in the squared circle” he laughed.

Searching for new horizons, Lewkowicz emigrated to the US at age 20 in 1971. Three yeasr later, he married his wife Ketty, his lifelong companion. They later had a son Nathan.

Two years later, Lewkowicz was working as a manager at the prestigious electronics store Jason’s 5th Avenue and later Joal 5th Avenue in New York City. While there, and based on his charm and personality, Lewkowicz established very warm friendships with the likes of Sylvester Stallone, Jack Nicholson, Paul Newman, ex-President Jimmie Carter Real Estate Tycoon Donald Trump and World Boxing Council President Jose Sulaiman.
Ingrid Bergman developed such a close friendship that she confided in him before anybody that she had been diagnosed with cancer.

It was while meeting Mr.Sulaiman that his interest in boxing returned. Lewkowicz soon took the plunge and signed his first boxer, middleweight Brian Barbosa and guided him to two important championship eliminator bouts versus Antwun Echols and Carl Daniels.

In 1997, Lewkowicz switched over to the role of internatinoal boxing matchmaker, doing shows in St.Thomas U.S. Virgin Islands. That same year he joined M&M Sports and brought them Barbosa, followed by none other than current pound-for-pound superstar Manny Pacquiao.
Soon to follow was Spaniard Javier Castillejo, as well as a pair of Venezuelans Yober Ortega and Jose Luis Valbuena and former lightweight champion Levander Johnson.

On January 15, 2000 in New York City’s famous Radio City Music Hall Lewkowicz organized the only boxing event ever held at this iconic venue The featured bout that night was between Roy Jones Jr. vs David Tedesco. In 2004 Lewkowicz produced another historical event in Louisville Kentucky where Mike Tyson was defeated by Danny Williams.

Lewkowicz works in South America with Arano Box Promotions where he guided Jorge “La Hiena” Barrios into a champion and created title opportunities for Jorge “Locomotora’ Castro and Wilfredo Vilchez among others.

Lewkowicz has represented fighters and made several historical matches with Golden Boy Promotions and was the brains behind “The World Cup of Boxing” during both editions of the event. (Mexico vs Thailand and Mexico vs Philippines).

With Sydney Olympic games silver medalist Sultan Ibragimov, Sampson and manager Boris Grimberg where able to make history as they developed Sultan from pro debut to a mandatory position, followed by winning the WBO Title from Shannon Briggs. Ibragimov successfully defended that belt against Evander Holyfield before losing it to Wladimir Klitschko.

Since Lewkowicz swithced over to the promotional side in January 2008, Sampson Boxing has grown into one of the world’s most prestigious promotional firms, representing many of the world’s best fighters and most promising young contenders.

Sampson Boxing has promotional partners all over North and South America, Africa, Asia, New Zelaland, Australia, Europe and Central America and Sampson Boxing events have been televised on such premiere networks as HBO, Showtime, ESPN, VS. and several international networks.
