About Us

We’re passionate about what
we do.

Dominica Costello, DO
Founder, Medical Director

Hello, I’m Dr. Dominica Costello.

I earned my Board Certifications in both Endocrinology and Obesity Medicine, and have enjoyed practicing in New England since 2006. 

I’ve had the pleasure of working at Portsmouth Regional Hospital, Anna Jaques Hospital and Lahey Beverly, and in January 2021 opened my private practice in Amesbury. It’s been the most rewarding career thus far, and keeps getting better! I love that I can organize my days to work best for my patients. I like being able to meet in person, do a quick telehealth visit or even just a quick phone check in- we can really work together and be so much more effective with this level of flexibility!

When I’m not with a patient or on a Zoom with my team, you can find me driving my family crazy taking food pictures in the kitchen, reading up on the latest scoop in both traditional and non-traditional health care, and forcing my husband and kids to come to hot yoga with me.

Jennifer Burns Katafigiotis
MS Director of Nutrition

Hi! I’m Jen. 

I have been passionately involved in the world of health, nutrition and weight management for as long as I can remember. I graduated from Fairleigh Dickinson University, and went on to earn a dual masters in Nutrition Education and Food Science from Montclair State University in New Jersey. In my “free time” I serve as an adjunct professor and mentor to undergraduate and graduate research students.

Long ago I took special interest in childhood overweight and obesity, the frightening emerging epidemic we are witnessing, and was moved by the lack of programs outside the clinical setting to help these kids and families. I had to do something, so I created a one of a kind nutrition education program for children – WWC KIDS. We launched at the American Academy of Pediatrics 2018 annual conference, and in 2019 we received an award from The International Forum on Advancement in Healthcare. I like to say that if I won the lottery tomorrow, I would still be working with my patients the very next day. It is simply what I love to do!

Danielle Peterson
Practice Manager

Hi there! I’m Danielle.

I have been involved in the medical field for about 20 years. I started off as a Medical Assistant and phlebotomist in a primary care and endocrinology office, and the rest was history. Anyone who has “met me” on the phone knows that I really do love solving problems and getting to know our patients. I started working alongside Dr. Costello in her endocrine practice in 2016, helped launch the medical weight loss program- NorthShore Weight Management in 2018, and was there when the doors opened at NorthShore Weight and Metabolism in 2021.

We can help.

Our mission is to provide a welcoming home for individuals looking to free themselves of excess weight, approach chronic health conditions from a holistic viewpoint, and start a journey together toward better health and happiness.
