She was recruited by Shirley Halili-Cruz as principal dancer and one of the original company members of the ballet company, Quezon City Ballet and was known for her interpretation of the Sugar Plum Fairy Grand Pas de Deux from the ballet, the Nutcracker. During her dance career in the Philippines, she performed extensively throughout the Philippines, including major theatres such as the Cultural Center of the Philippines, Folk
Arts Theatre, the Metropolitan Theatre and the Meralco Theatre.

She also took several workshops and continued her training abroad, attending classes at the Zurich Opernhaus (Switzerland), Ohkura Ballet and Matsuyama Ballet (Tokyo), Broadway Dance Center (Tokyo and New York), Professional Dance Center (Tokyo), the Joffrey Ballet School (New York), Alvin Ailey School (New York) and garnered a scholarship award with the American Theatre Dance (New York).

As she finally moved to the United States in 1995, she was immediately boarded under the wings of the South Bay Ballet in Torrance, California where she premiered her award winning choreographies, Adagio A Sigh and A Prayer’s Response, among others. See choreography list for details.

Ruby Karen strongly believes that as a dancer, a performer, a teacher, a choreographer, a coach and a dance advocate, one has to maintain and continually educate oneself through workshops and classes. She alternates and at times, catches 2 classes a day in ballet, modern, gymnastics, aerials and goes to the gym on top of her busy dance rehearsals and managerial tasks. She also believes that if you want to be on top of your league, you have to compete with yourself and strive for improvement. She is grateful for the following schools, dance companies and individuals that provided and currently provides her with training including, Tonya & Ray Pierce, Stefan Wenta, Deborah Brockus Project Dance Company, New Hope Gymnastics, Ballet Pacifica, Hysterica Dance, Tongue, Diavolo, Focus Fish and Orange County Dance Center. She is grateful and extends her appreciation to these dance institutions that continually support the arts and the performing arts in general.

• MODERN: Professional Dancer; company member and collaborate efforts with dance companies e.g., Inspiration (Tokyo); Brockus Project Dance Company (Los Angeles) and independent contracts
• ACRO-GYMNASTICS AND ADAGIO PARTNERING: Mastered this artform and incorporated her skills in various dance discipline, more so in Salsa and Adagio. It is in this artform that she saw the need to go independent and explore her skills to its fullest which gained her recognition locally and internationally. Due to the overgrowing demand for her style, she saw the need to produce her own Aerial Lift and Tricks Instructional DVD (released in 2006) and teach these movements in all appearances and invitations around the globe.
• SALSA: Professional career since 2004. Traveled, taught and performed in many countries and cities around the world.
