Grow HR consultant Mandy Cartwright has become a director after six years with the company, replacing founding director Murray Cowan.
Grow HR director and co-founder Dave Robb said her appointment was part of an orderly succession.
"She became a shareholder three years ago and in a planned move she now joins the board reflecting her continued growth and development," he said.
"Our philosophy is that Grow HR shareholders and directors are actively involved in the business, and we couldn't be more pleased to see our succession plan working so well.
"We'll definitely miss working with Murray, and I know that his next business venture will also be a real success."
