Within a few years his songs had been recorded by Mercury Records artists Len Wade and the group Chance. One of the songs, "She Told Me Yes" reached the national top 40.

A year later Lee Greenwood released Rob's song, "Holding a Good Hand" which went to #1 on the country chart and that same year Rob was signed to Arista Records. His first three singles reached the top ten and Rob began touring with Travis Tritt, Reba McEntire, Brooks and Dunn, Billy Ray Cyrus and others. During the nineties Rob opened shows for Garth Brooks, Alan Jackson, Willie Nelson, Merle Haggard, Restless Heart, Exile and others, and performed in clubs and festivals Worldwide. In 2001 Rob scored another #1 with “Concrete Angel”, which was co-written with Stephanie Bentley and recorded by Martina McBride. Rob's duet with Carl Perkins "A Mile out of Memphis" held the #1 position on the UK-based HotDisc chart for five weeks. While devoting most of his time to writing, Rob continues to perform often.
