Functional & integrative medicine www.integrativepediatricsli.com

I am a certified pediatric nurse practitioner (CPNP) specializing in integrative and functional medicine, looking for root causes of illnesses and always thinking “outside the box.” I care for children and their families all over the country, treating the whole child, not just the symptoms. Our goal is always to provide exceptional health care while also educating and empowering parents so they can be their child’s leading advocate, and developing and delivering evidence-based treatment plans using the most cutting-edge research. I have treated Autism Spectrum Disorders, PANS/PANDAS, allergies, and mitochondrial and metabolic disorders, among many others.

Staying healthy doesn't come from holding a lucky charm, picking a four-leaf clover, or seeing a pot of gold at the end of the rainbow. 🍀🌈💰 Feeling your best comes from understanding what your body needs and supporting it in the right way. At Integrative Pediatrics, I work with children and adults to take a closer look at what may be affecting their health. From nutrition and gut health to immune support, lab testing, and getting to the root cause, my goal is to help your whole family feel their best.

If you’re looking for answers or want a more personalized approach to your health, let’s start the conversation.

Because real health isn’t about luck; it’s the result of the right guidance and care. 🍀

This International Women's Day, we aren’t just celebrating how far we’ve come, but focusing on the foundation that keeps us going. As a woman-owned practice, I know that when we prioritize our health, our families and communities thrive. One of the most overlooked "superpowers" in a woman’s wellness toolkit? Protein. 🥩🫘

It’s more than just a macronutrient; it’s the building block for:
➡️Hormonal harmony
➡️Bone & muscle strength
➡️Immune defense
➡️Making enzymes and hormones
➡️Storing nutrients
➡️Source of energy

Good sources of protein include:
➡️Quinoa - complete protein, naturally gluten-free
➡️Eggs
➡️Meat and fish
➡️Nuts and seeds

Today, let’s honor the strength of women and the simple, daily choices, like fueling our bodies well, that make that strength possible. How are you fueling your "superpowers" today?

When a child comes into my office, I take my time and look at the whole picture. 💛

I focus on four important areas:

🧪 Vitamin and mineral deficiencies
🦠 Infections
🌿 Allergies
🧬 Toxin exposure, including MTHFR, and how your child’s body detoxifies

These are often the missing pieces that can impact how a child feels, grows, and thrives.

That’s why the lab work I order is thorough. I want parents to have real answers and children to get the support they truly need.

Children are our future. Let’s help them thrive.

Here are some heartfelt words from another happy mom!

Did you know quinoa isn’t a grain? It’s actually a seed! 🌱 This little powerhouse is naturally gluten-free, packed with protein, and full of fiber, antioxidants, and essential nutrients like B vitamins, iron, and potassium. It’s one of my favorite simple swaps to support digestion, energy, and overall wellness, especially for growing kids.

Try tossing cooked quinoa with cucumber, tomato, onion, olive oil, and lemon juice for a quick, gut-friendly salad. There are so many small, doable ways to use food to support your child’s health, and I’m here to help you figure out what works best for your family. 💛

💊 Tylenol – Avoid or Not to Avoid?
Acetaminophen (Tylenol) can deplete glutathione, your body’s most important detox antioxidant. This matters even more if your child has an MTHFR gene mutation, which makes detox harder. Not sure if your child has it? Let’s talk. Together, we can explore safer options and support your child’s health from the inside out. 💛

| Many parents ask, “What’s the best way to detox my child?” My answer is gently and naturally. Start with food:
➡️cruciferous veggies
➡️fiber-rich foods
➡️bitters like turmeric and dandelion

It's important to support daily bowel movements and encourage sweating through movement and play. Then unwind with an Epsom salt bath to help the body release toxins. Let’s help the body do what it’s designed to do safely.

Need guidance? I’m here to support your family’s wellness journey.
