About Colleen

I am a registered dietitian, personal trainer and wellness expert. My wealth of knowledge comes from a blend of life experiences, higher education, and years of working with people from all walks of life. I have an MS in Nutrition and Public Health from Columbia University and an undergraduate degree in Nutrition and Food Science.

I have worked as a personal trainer and group fitness instructor in New York City for the past 25 years along with holding certifications in Thai massage and as an Iynegar yoga instructor. I have also trained and competed in Muay Thai Kickboxing.

My career as a clinical dietitian has allowed me to work with all types of disease states including eating disorders, high blood pressure, diabetes, diverticulitis, Krohn’s disease, Celiac disease, cancer, eating disorders, strokes patients, HIV/AIDS and overweight/obesity.

My philosophy is that diet and exercise work together to create optimal health and wellness.
