Rose made his debut opposite Robin Williams and Julie Kavner in Woody Allen's Deconstructing Harry. Born to a would-be Rabbinical cantor and an opera singer, Rose embraced music at an early age and excelled at Tap, Jazz, Ballet, and the martial arts training he underwent. It was during this same time that Rose was cast to be the voice of Peanut for three years, as the title-character on PB & J Otter, a cartoon on the Disney Channel. Soon after Rose would perform under the direction of Michael Mayer (Spring Awakening, Thoroughly Modern Millie) alongside Kristen Johnston and John Pankow in Peter Hedges' Baby Anger. The successful portrayal of a young boy with cancer led to subsequent guest spots on TV's Ed and Third Watch. Having developed a passion for live theater, Rose landed a role on stage with Theodore Bikel in The Gathering and went on to tour with three consecutive productions - including the pre-Broadway tour with Hal Linden. Throughout his time on stage and in recording booths, Rose continued to grow his love for dance, and at age 15 went on to become the youngest to ever teach dance at the renowned Broadway Dance Center in New York. While continuing to study the dramatic arts at New York's famed LaGuardia High School of the Performing Arts, he appeared on the hit series The Sopranos and the Comedy Central movie The Hebrew Hammer, starring Adam Goldberg. It was soon after that Rose had the honor of working with Noah Baumbach, Jeff Daniels, Laura Linney, and Anna Paquin in the Oscar-nominated The Squid and the Whale, as Otto - the best friend of Walt, played by Jesse Eisenberg. After four years of Shakespeare, character study, dialects, clowning (-study, not literally), vocal and dance training and all other school subjects, Rose was done with High School and ready to head west. The exodus was aided by his role on the production of Dead End, directed by Nicholas Martin at the Ahmanson Theater in Los Angeles' famous Music Center. Rose starred as Angel, one of the Dead End Kids, alongside Jeremy SIsto, Tom Everett Scott, Joyce Van Patten, and Kathryn Hahn. He later appeared in HBO's Voyeur Internet project, directed by Jake Scott, and soon after earned a role in Kenneth Lonergan's Margaret. Rose once again found himself on-set with Anna Paquin, along with Matthew Borderick, Matt Damon, Mark Ruffalo, and Kieran Culkin, just to name a few. While still acclimating to life in LA, Rose continued to make appearances on many hit TV shows.
