I’m Casey Seiden- registered dietitian, certified diabetes care and education specialist, and a mom with a passion for helping women thrive, wherever they are along their pregnancy journey.

Whether you are just starting to think about growing your family, in the thick of a pregnancy, or find yourself a few months postpartum, I want to support you in feeling your best, finding peace with your changing body, enjoying delicious foods, and having a healthy baby and future.

As the dietitian at the premier maternal fetal medicine practice in Manhattan, I have helped hundreds of women have healthy pregnancies and babies. I take a compassionate, but always evidence-based, approach to prenatal care and would love to take the guesswork out of what and how to eat before, during, and after pregnancy.

The journey to conceiving and getting pregnant may seem simple, but it isn’t always for everyone. I know this from personal experience, and it’s why I am committed to what I do.

I know all too well what under-eating and over-training can do to a woman’s health. I convinced myself that my dedication to running was just a healthy passion. I thought I physically looked great, and was so proud of my incredibly vegetable-heavy, plant-based meals. I was driven, a hard-worker, and perfectionist, who assumed that stress was just a part of being a professional building her career.

When I wanted to start my family, it became clear that many of the ways I was living my life had to change. I needed to slow down the pace and take rest days. I needed to eat way more and allow my body to change. I needed to be more present and let go of demanding projects.

With patience and support, my body came back to center, and we were blessed with a pregnancy and healthy baby.

Healing my own relationship with food and my body was the best thing I could have done to prepare myself for pregnancy and beyond, and now I want to help YOU have the healthiest pregnancy and life possible.

You deserve more than quick fix diets for fertility and your hormonal health.

You deserve expert recommendations to support you and your growing baby.

You deserve a compassionate approach to balancing your blood sugars.

You deserve to feel free to eat all foods.

I’m here for you, mama.
