Len Smith is the new regional adviser for Wales and will develop training, education and membership. He will forge links with governing bodies, colleges and councils.
"Training and education are the foundation of the institute and there's a big market for both in Wales," said Smith, whose career started at Radyr Golf Club.
He has been responsible for grounds at the former Polytechnic of Wales, Cardiff Athletic Club, Cardiff City and most recently at Glamorgan CCC.
Ian Lacy, head of professional services, said: "It's rare to come across someone of Len's experience and qualities.
"We are pleased we can now count him as a key player in our regional network of advisers."
