Internationally, Marcus Monroe has brought his unique brand of humor, wit and specialty juggling to venues as varied and exciting as the Edinburgh Fringe Festival in Scotland, Brighton Fringe Festival in England, Cirkus Cirkor in Sweden, and the Shoebox Tour in Canada and cities throughout the world including Amsterdam, Madrid, London, Hong Kong, Paris and Seville. He recently performed an astounding 150 shows in China at the Venetian in Macau. In addition, Marcus has become one of the strongest headlining acts on Princess, Carnival, and Royal Caribbean Cruise Lines. In the U.S. he has entertained at sold-out performances in major locations from coast to coast, as well as universities across the nation. Marcus also has several national tours under his belt performing solo and with some of the world's best specialty acts and alternative comedians.

His technically difficult juggling routines combined with his electric on-stage presence inspired the New York Press to dub Marcus "the rock star of jugglers!" making him a much sought-after act for many of today's hottest music acts. A few of the acts Marcus has shared the stage with include Aimee Mann, CAKE, Talib Kwali, Hanson, and Gavin DeGraw. CAKE recounted their experience with Marcus on their official website: "What was most memorable to us this evening was the performance from juggler Marcus Monroe!"
