Gregory Niebel started his classical theatre training at the age of thirteen with the Children’s Experimental Theatre in Carmel, California. He moved to Los Angeles in his 20’s to pursue his career after years of performing in numerous productions on the Monterey Peninsula. Not long after he arrived he had the chance to debut his professional career at The Ahmanson Theatre in the Royal Shakespeare Company production of “A Patriot for Me” starring Alan Bates. While he spent the next ten years working at his craft, performing in a variety of television shows and theatrical films as well as equity-waiver theatre, he was also working his day job in the high-end, fashion forward retail industry.

In 1991, he had the opportunity to buy the store, BNY, in Santa Monica, and make it his own. This he accomplished with great success, achieving the reputation of one of the finest small boutiques of avant-garde men’s and women’s fashion in the Los Angeles area. During this period of time, he withdrew from the acting world to concentrate on his business, but his love of theatre and film was never far from his mind, always incorporating it into his fashion sense and store presentation.

 He has since returned to the craft of acting and while he has been concentrating on working on feature films, short films, TV and commercials, he has especially enjoyed getting back on the boards. His first venture was in a Company of Angels production of the premiere of “Their Eyes Saw Rain”, where he portrayed the pivotal role of Dr. Landy/Daddy and was honored with an LA Weekly Annual Equity Waiver Award nomination for Best Supporting Male Actor. Not soon after that he was back on the boards at The Barnsdall Gallery Theatre for the production of “The Things That Make Men Cry: in which he played Mel, the co-owner of a black barbershop. Thereafter he began rehearsals for another original two act “Homecoming” at The Sherry Theatre in NoHo where he portrayed the male lead, Father, an alcoholic Vietnam vet in a dysfunctional family. He was booked on 4 episodes of a new 2019 cyber-thriller TV series "Cypher" to play the role of Dan Malone. It is produced by Aroma Studios and distributed  by Netflix and released on Roku in March 2021.
