The sponsorship deal is part of RSM's ambitious partnership strategy within golf, to continue to build brand awareness across RSM's international network spanning 116 countries.
Colin becomes the latest member of Team RSM, joining fellow golf professionals such as European Tour players Andy Sullivan and Paul Waring, PGA Tour players Zach Johnson and Chris Kirk and fellow former Ryder Cup captain Davis Love III.
As part of the sponsorship deal, Colin will wear the RSM logo on his shirt during tournaments as well as act as an RSM ambassador through personal appearances and social media.
Colin Montgomerie is one of his generation’s most recognisable sports stars and is a true statesman of golf. Known affectionately to millions around the world as Monty, he is probably best known for his Ryder Cup record. Colin played in eight Ryder Cup Matches and was unbeaten in his eight singles matches, and in October 2010 he captained the victorious European Ryder Cup Team at Celtic Manor.
Colin turned pro in 1987, becoming Europe's No.1 in 1993, a position he retained for an unprecedented run of seven years and winning eight European Tour Order of Merit titles. In 1998 he was honoured with an MBE, and in 2005 he collected an OBE from H.R.H. Prince Charles.
Colin continues to play on the main and seniors tours in Europe and the Champions Tour in the United States.
Colin Montgomerie said: 'I am delighted and very excited to be joining RSM as a golf ambassador, representing them on both the European Tour and in the USA on the PGA Tour Champions. To be partnering with RSM at this time in my career, and at the same time as their success continues to grow is something I am very much looking forward to being a part of.'
David Gwilliam, Chief Executive Officer at RSM UK, said: ‘Colin is a great ambassador for the game of golf, and I am delighted that he has agreed to take on the role of ambassador for the RSM brand. He has a loyal worldwide fanbase, he is a consummate professional and he embodies RSM's core values. We look forward to being part of his continued success as a member of Team RSM.'
