Nicknamed "The Tongan Warrior", Wolfgramm earned the Super Heavyweight silver medal at the 1996 Summer Olympics, making him the first and only athlete from Tonga to win an Olympic medal.

At 6'4" and 325 pounds, the huge Wolfgramm turned pro after the Olympics, but had limited success.

Although he was able to beat former Cuban Olympian Jorge Luis Gonzalez by decision to set up a fight with Wladimir Klitschko for the vacant WBC International Heavyweight Title, he was beaten in the first round in a rematch of their 1996 Super Heavyweight Olympic finals bout.

He later lost a decision to Eliecer Castillo, but beat Jimmy Thunder to set up a fight with Corey Sanders in late 2001.

Sanders won via 9th-round TKO, and Wolfgramm announced his retirement shortly after this fight.
