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 ca

n 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.

After sharing all the health benefits of quinoa at her annual visit, this little Miss left the office adamant that she would not like it or even want to try. About an hour later, mom sent this picture thanking me for the suggestion with the caption:

"Mom, take a picture of me to send to Mariel. I love quinoa!"

Kudos to them both!!!

Sometimes children experience symptoms that don't seem connected at first. Fatigue, brain fog, congestion, headaches, sleep disturbances, and frequent illnesses can have many possible causes. In some cases, environmental factors may be contributing to the problem.

Exposure to mold and mycotoxins can occur through water-damaged buildings, contaminated foods, or mold particles in the environment. Because symptoms can overlap with many other conditions, mold exposure is often overlooked.
If your child has ongoing symptoms and you're struggling to find answers, it may be time to look deeper.

Let's find out if mold or mycotoxins could be affecting your family's health.

When people think about serotonin, they usually think about mood. But your digestive system plays an important role, too.
The gut and brain are constantly communicating, which is why gut health can influence mood, focus, sleep, and overall well-being.

Supporting healthy serotonin levels doesn't have to be complicated. Daily bowel movements, quality sleep, time outdoors, and nutrient-rich foods can all play a role.

The body is wonderfully connected, and sometimes improving one area can positively affect many others.

Every child deserves a safe, comfortable place to sleep. 🛏️💙

When I learned that children right here on Long Island were facing food insecurity and sleeping without a bed of their own, I knew I had to do something.

Together with my incredible Ronkonkoma Rotary family, we founded the Sleep in Heavenly Peace – Suffolk County Chapter to make sure no child has to sleep on the floor.

Our volunteers build and deliver brand-new beds—complete with a mattress, pillow, sheets, and comforter—to local children in need, completely free of charge.

Now, you can help us make an even bigger impact!

We're collecting new bedding essentials, including:
🛏️ Twin mattresses
🛏️ Pillows
🛏️ Handmade twin bedding
🛏️ Twin "Bed-in-a-Bag" sets

Every donation—large or small—helps transform an empty space into a cozy place where a child can rest, grow, dream, and thrive.

Please take a moment to look at the flyer for our wish list, donation drop-off locations, and additional details.

Thank you for helping us ensure that No Kid Sleeps on the Floor in Our Town. ❤️

When parents hear about heavy metals, one of the first questions they ask is, "Where are they coming from?" The answer may surprise you.

Everyday exposures can come from things like drinking water, certain foods, spices, and even products we use regularly in our homes. Children are especially vulnerable because their brains and bodies are still developing.

That's why I believe it's important to understand what your child is being exposed to and whether it could be contributing to symptoms that don't seem to have clear answers.

Sometimes finding the missing piece starts with asking the right questions.

Summer hydration doesn’t just come from water bottles. Many fruits are packed with water, vitamins, and antioxidants that help keep children hydrated and feeling their best during the warmer months. Some of my favorite hydrating summer fruits for kids include:

🍉 Watermelon – rich in water and lycopene to support hydration and overall wellness
🍓 Strawberries – packed with vitamin C and antioxidants for immune support
🍍 Pineapple – contains vitamin C and digestive enzymes to support gut health
🍊 Oranges – hydrating and full of vitamin C for the immune system
🍇 Grapes – refreshing and rich in antioxidants that support growing bodies
🍑 Peaches – high in vitamins A and C and naturally hydrating
🥝 Kiwi - high in Vitamin E and antioxidants

Simple foods can make a big difference for growing children. 💛

Today’s children are exposed to more chemicals and environmental toxins than ever before. From pesticides and plastics to contaminants in drinking water and heavy metals like mercury and aluminum, these substances can impact a child’s developing brain, behavior, focus, and overall health. While we can’t avoid every toxin, we can take steps to reduce our exposure to toxins and better support our children’s growing bodies. At Integrative Pediatrics, my goal is to help children thrive so they can be the best they can be. 💛

When parents feel dismissed or told to “just wait it out,” it can feel frustrating and isolating. At Integrative Pediatrics, I believe in looking deeper to understand the why behind a child’s symptoms, not just masking them. Every child deserves individualized care, thoughtful evaluation, and support that helps them truly thrive. I’m so grateful for families who trust me to be part of their journey and honored to help guide them toward answers and healing. 💛

Every child deserves a safe place to sleep. I'm excited to announce our very first Suffolk County Bed Build on June 19 in Farmingville.🎉🔨 As a pediatric nurse practitioner, I've seen firsthand how important quality sleep is to a child's physical, emotional, and mental well-being. That's why I am honored to bring Sleep in Heavenly Peace's mission to Suffolk County.

According to Sleep in Heavenly Peace, an estimated 2-3% of children in the United States do not have a bed of their own. No child should have to sleep on the floor. 😔🛏️
