Jill Merrigan, MS, RD

Registered Dietitian

Meet Jill!  Growing up in Western Massachusetts, constantly surrounded by fresh foods, Jill developed a passion for good food, even at an early age. When Jill was growing up, she was an avid, competitive athlete, and knew from her love for food, she needed to properly fuel her body to support her hours on skates playing ice hockey, or on the field playing lacrosse.

Combining her love for good food with the knowledge on how to properly fuel one’s body on the athletic field, Jill became passionate about nutrition and educating others!

After her time on the field and rink came to an end, Jill decided to attend St. Lawrence University, where she pursued a degree in English. Following graduation, Jill packed her bags and headed off to NYC where she pursued a career in the magazine industry.  

Although Jill had a thriving career in the big apple, she knew she had a greater purpose in life, and simply could not detach from the idea of educating people all over about the importance of nutrition. After having this realization, Jill moved to Boston to attend Simmons College in 2011 to embark on her career in nutrition. 

Jill continued on to complete her dietetic internship at Simmons College and pursue an MS in Applied Nutrition from Northeastern University. And as 2015 approached, Jill completed further training in the LEAH (Leadership Education Adolescent Health) Fellowship at Boston Children’s Hospital. This training provided Jill with skills to work on a multidisciplinary team while becoming an expert in adolescent health and the outpatient management of eating disorders and disordered eating.

Jill’s current work includes a holistic blend of Intuitive Eating, Motivational Interviewing, HAES (Health at Every Size) while her goal is to always meet her clients where they are at.  

Today, Jill is a full-time dietitian at Metrowest Nutrition and sees clients in our Newton office.  She loves to take advantage of the New England scenery while running or hiking with friends or spending time with her family on the Cape Cod beaches!!

Jill is a member of the Multi-Service Eating Disorder Association and a Licensed Dietitian/Nutritionist.
