He joined the ATP professional tour at the age of 20 in 1998 having played collegiately at Mississippi State University.

Although Larose did not make any official announcement, he was quoted in the press as saying that he retired from tennis after being levied a two-year ban in February 2005 by the ATP for testing positive for cocaine.

Simon made Canadian radio history when he provided analysis on the first-ever Canadian English language production of the 2010 Rogers Cup tennis final along with CJAD 800's Rick Moffat (play-by-play) and Mark Shalhoub (courtside reporter).

Larose provided CJAD 800 coverage for the 2012 Rogers Cup and returns to the booth August 10–11 for the Men's Singles Semis and Final.
