She specialize in metabolic health, including weight loss and insulin resistance, as well as digestive concerns such as IBS, food sensitivities, bloating, and chronic GI discomfort.

As a first generation Italian American, Rosanne aspires to share her passion for the Mediterranean lifestyle and its many life giving benefits. In her spare time she enjoys cooking up quick and easy gluten free recipes for her family and meeting her step goals during long daily walks with her rescue dog, Luna.
