Weight Loss Diet

I've been to at least a half dozen nutritionists before I found Madeleine. I hit the jackpot with her! Lauren W - Yelp review

Exercising with clients

Madeleine told me to cut WAY back on the wine and crank up the exercise...and it worked! Also very sensible advice about supplements (they're a waste of $$) and great tips on weight loss while dining out.  She is really the most reasonable nutritionist I have ever dealt with and she didn't try to sell me anything! I highly recommend her.  Andrea V - Yelp review
