Two Madrid-based fighters have traveled to a newly established 340 Boxing/Sampson Boxing training camp in the island paradise of St. Thomas, U.S. Virgin Islands, to prepare for their upcoming fights.

Sampson Boxing’s own former light heavyweight world champion and IBF #13-rated Gabriel “El Chico Guapo” Campillo (25-7-1, 12 KOs) and WBC #11-rated Luciano Leonel “El Principito” Cuello (35-3, 17 KOs) are working hard at the 340 Boxing Gym in St. Thomas, USVI with trainer Matias Antonio Gonzalez and two world-rated locals, John “Dah Rock” and Julius “The Chef” Jackson.

On Saturday, September 12 at the Foxwoods Resort in Mashantucket, Connecticut, (and live on NBC) Campillo will face undefeated “Sir” Marcus Browne (15-0, 11 KOs) of Staten Island, New York, on the undercard of the Peter Quillin vs. Michael Zerafa event.

And on Tuesday, September 22, at the Hollywood Palladium in Hollywood, California, (and live on USA FOX Sports 1) Cuello will face undefeated Philadelphian Julian “J Rock” Williams (20-0-1, 12 KOs) for the WBC Continental Americas super welterweight title.

“I wish to thank our generous sponsor, Cardow Jewelers, for their help with establishing this ‘training camp in paradise,'” said Lewkowicz. “I also wish to thank my valued partners in the Virgin Island, 340 Boxing. The two fighters are getting excellent work with the Jackson Brothers and their team and will be in fantastic shape for their fights.”

Both Campillo and Cuello are managed by former world champion Sergio “Maravilla” Martinez.

Sampson Boxing now currently maintains training camps in Las Vegas, Boston, New York, Los Angeles, the Virgin Islands and a full camp in Cebu City, Philippines, for Jonel “Kid Pacquiao” Dapidran.

After a very successful run as a matchmaker and adviser, Sampson Lewkowicz switched over to the promotional side of professional boxing in January 2008.

Sampson Boxing has promotional partners all over North and South America, Africa, Asia, New Zealand, 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.
