Holistic Children's Health with Mariel Nasis

What happens when a parent knows something is off, but every test says their child is “fine”? In this episode of The Well Known Podcast, Shannon Conklin sits down with Mariel Nasis, founder of Integrative Pediatrics of Long Island, to explore what personalized pediatric care can look like when a practitioner has time to listen, connect the dots, and see the whole child. They discuss parent advocacy, gut health, nutrition, sleep, environmental exposures, individualized testing, and why helping kids thrive requires more than a one-size-fits-all approach.

What You’ll Learn

  • Understand why Mariel starts with the whole child—not just one symptom or one lab result.

  • Learn why listening to parents can uncover details that may otherwise be overlooked.

  • Explore how diet, sleep, stress, gut health, activity, and family habits can all be part of a bigger health picture.

  • Hear why supplements and detox protocols are not automatically the first step in Mariel’s approach.

  • Learn how parents can ask better questions, stay informed, and find practitioners who will listen.
