What our clients say...

Lori C.
"I have never had to enlist the services of a dietician in my past. Having been diagnosed with a heart condition the pounds kept packing on, no matter what I tried to do I couldn't seem to lose the extra weight.
A friend recommended Fiona. I was unsure at first about what to expect. I must say I was pleasantly surprised. She is very kind and caring with a wealth of information who went to work on my situation and created a diet for me. 1 week in and I have lost 2 pounds as well as 3 inches from my waist! I know that she is always available to support me through out my weight loss journey which is very comforting.
I would very highly recommend her to anyone wanting to improve their health."
