Sihing Alexander Brown is a senior student of Sifu Vingrove Thomas, and was the first President of the Columbia University Kung Fu Club, which he helped to establish. He was the club's assistant instructor from 1991 to 1998, and has been the primary instructor since 1999.

His martial arts training began in 1982, when he joined the Shorei-kan Dojo in NYC. There he studied Okinawan Goju-ryu Karate-do with Sensei Ichiro Naito.

He joined Sifu Lee Moy Shan's Ving Tsun (Wing Chun) Athletic Association in 1986, around the time that Vingrove Thomas was named Lee's successor. Brown and others then became students of Sifu Thomas at his first school, the Ving Tsun Kung Fu Institute.

Since then, Wing Chun Kuen has been the focus of Mr. Brown's practice, though he has also received instruction in Xinyiquan. Over the years, he has represented Sifu Thomas in exhibitions, tournaments, television and videotape appearances, and in writing.

At Columbia, his alma mater, he hopes to maintain the standard of training for which his teacher's own school, the Six Harmony Martial Arts Academy, is known.
