He spent a year in Arkansas, but turned professional in late 2008 having reached the final stage of qualifying school for the European Tour. Playing the final stage as his first professional tournament, Colombo finished T29th and earned a place on the European Tour for 2009. After a slow start, making only one cut, Colombo concentrated on the second-tier Challenge Tour, and subsequently played full-time at that level for two further seasons, with a best result of T2nd in the 2010 Kazakhstan Open.
In 2011, he recorded eight top ten finishes in 20 events to finish seventh in the rankings and secure a return to the European Tour.
