Nutrition for every stage, from trimester zero to the fourth trimester.
I help couples build the nutrient stores that support a healthy pregnancy and their baby's brain development, starting before conception and continuing through postpartum.

Let's rethink pregnancy planning.
Most of us take a year to plan a wedding, or train for months to run a marathon. Pregnancy deserves the same care. I focus on the nutrient stores that build your baby's brain from the very first weeks, often before you know you're pregnant, so you can start pregnancy ready.
Preconception Preparation
6 to 12 months before trying
Your baby's brain, heart and organs form in the first 8 weeks, often before you know you're pregnant. We build the nutrient stores those weeks draw on, while egg and sperm are still maturing.
- Iron and DHA stores that last through the third trimester
- The prenatal vitamin that's the best fit for you
- A healthy microbiome to pass on at birth
- Support for fertility, including IVF or IUI
Pregnancy Support
Trimester by trimester
Your baby is building billions of neurons, and in the third trimester each one starts getting wrapped in myelin. We make sure the fat, DHA, iron and cofactors are there for every stage.
- What to eat each trimester for you and your baby
- Brain-building nutrients and the right prenatal
- Iron and DHA stores that last to birth and beyond
- Which symptoms are normal, and when to call your provider
Postpartum Program
Starts in the third trimester
Within days of birth, your hormones go through one of the fastest shifts of your life, while your body heals and makes milk. Nutrition helps carry you through.
- Meal prep and fueling for birth and recovery
- Rebuilding iron and nutrient stores
- Steadier energy and mood
- Support with milk supply, formula and baby's digestion
Planning a pregnancy in the next year?
Start 6 to 12 months ahead. The egg and sperm that become your baby are developing right now, and some nutrient stores take months to rebuild.
What clients say
I was lucky enough to find her and start working with her two months before I became pregnant, which gave me such a valuable head start going into pregnancy… She taught me about things I would never have thought to ask about, from placenta positioning to the importance of iron during pregnancy and breastfeeding.
— Bella G.
Denise was essential to helping me feel my best, both physically and mentally, throughout pregnancy and postpartum. She recommended additional labs, interpreted my results with greater care than my doctors, adjusted what I was eating based on them, was a compassionate listener, and so much more.
— Sydney C.
She has guided me through my preconception journey with the utmost kindness and support… Together we made a step by step plan that has given me so much insight to what my body needs.
— Carley W.
She offered recommendations on key bloodwork for early pregnancy, identifying certain deficiencies before any doctor could! She has continued to guide me through my first pregnancy.
— Eileen B.
Hi, I'm Denise.
For almost 20 years, I helped assess and tutor children and adults with ADHD and learning differences. I wanted to focus on prevention, which led me back to school for a master's in nutrition and functional medicine, and to the research on the first 1,000 days.
Nest Nutrition brings that together: understanding how nutrients build the brain in critical windows of development, and helping you have them in place when it matters most.
