Background

I’m a Registered Dietitian who’s been helping people reclaim their health and confidence for over 40 years. I specialize in diabetes, weight management, cardiovascular health, digestive wellness, gastroenterology, and nephrology.  I’m a Certified Diabetes Care and Education Specialist, a certified insulin pump trainer, and hold advanced certification in Adult Weight Management from the Commission on Dietetic Registration. I also spent 23 years as an adjunct instructor in the Nutrition and Food Sciences Department at Montclair State University.   When I’m not working with patients, you’ll find me cooking, traveling with my husband, spending time with my adult children and friends, caring for our pets, or training for walk-run half marathons. Let’s connect — I’d love to be your partner in the journey toward better health and wellness.

Jane completely changed how I think about food. She’s patient, knowledgeable, and explains things in a way that actually makes sense.
