I would HIGHLY recommend Sandy for anyone dealing with nutritional issues.  She is extremely knowledgeable and a tremendous help to my teenage daughter who was diagnosed with an intolerance to Gluten, Lactose and- Fructose.  Sandy helped her get on track with her foods and habits – just in time to go away to college.  Thank YOU Thank YOU!!!
