More about Marianna

 What is one thing you would want patients to know about you?

Nobody's diet is perfect!  A lot of times patients will often think that as a dietitian my diet is “super clean.” I am here to tell my patients that I am a person who enjoys all types of food! Over the years I, myself have learned to live a balanced lifestyle incorporating all foods within my diet. My main goal is to never judge but guide my patients to live a life not on a diet, and to live without guilt and restriction around food.

How do you go about making your treatment plans for FORM patients?

Getting to really know the patient. Understanding a patient's preferences, nutritional needs, health issues, culture, and beliefs surrounding food all go into creating a plan for the patient. Treatment plans are something that needs to be individualized, it’s never one size fits all!

Why do you love working with FORM patients?

Combining my passion for nutrition and helping people is the reason why I love working with FORM patients! Nothing gives me greater satisfaction than helping my patients achieve their health and nutritional goals
