What people I have helped say:

Hear from my satisfied customers who have experienced the quality and value of my services.

I didn’t know I was in need of a dietician until my family staged an intervention and contacted Donnay to help get my sugar diabetes under control. Not only has Donnay succeeded in getting my sugar down and stable with changing my eating habits but I have also lost 14kgs. The encouragement and personal care I have received from consulting with a dietician has been life-changing! Thanks very much to my family and Donnay – from the heart!

– SHEILA VAN STRATEN

Donnay has helped me a great deal to keep on track. It is difficult to eat sensibly on a regular basis, but knowing that I will get a check on my weight and waist-line once a month is a huge incentive to stay healthy! She comes to my home once a month and we go through how things have been going. One thing I must remember is to drink more water!

– BARBARA JOHANNESSON

When I really wanted to lose a few kilograms to fit into my much loved jeans again, Donnay worked out a great eating plan for me. Not only was it easy to follow but most of my favourite foods were incorporated and I didn’t starve to death. With loads of support and encouragement, Donnay helped me to fit into my jeans again and also equipped me with an eating plan that easily became a healthy lifestyle.

– LEANDRA WILLIAMSON

Donnay Gallinetti is a well versed dietician with extensive medical knowledge. I have had the pleasure of having Donnay assess and council me with regard to my dietary needs for the past 2 years. I find her to be a very pleasant, softly spoken professional who has a good listening ear and is always ready to give advice in a gentle, encouraging manner with no judgement. Donnay goes the extra mile to assist in any way, such as obtaining medical results in order to advise correctly and will even create eating plans according to specific needs.
I have no hesitation in recommending Donnay as a personal dietician.
