“I value keeping a balance in my life. And being healthy is a big part of that for me. When helping others to do the same it’s really rewarding. I love healthy food and coming up with great new recipes. I also enjoy keeping active – being outdoors and keeping a routine with exercise really works. All this together with having great friends and having fun keeps me happy.”
