We Are Saving Pediatrics — Results of the 2025 Zest National Direct Pediatric Care Survey

This year, 99 pediatricians across 30 states responded, representing an estimated 60%-70% of all pediatric DPC practices nationally. The results are simply extraordinary.

What Theo Knew: Raising Children Who See the Best in Others

What Would Theo Do? A Lesson for Every Parent

The World Is Their Classroom: Raising Culturally Curious Kids

Last month, my wife Linda and I were supposed to be in the UAE and Egypt. Instead, a conflict in the Middle East sent us pivoting to somewhere we never expected — and reminded me of something I think about often as a pediatrician and as a parent.

This month's blog is about the gift we give our children when we expose them to cultures different from their own. Not through grand international travel, but through the intentional, accessible experiences that are available to most of us right here at home. Cultural curiosity builds empathy, resilience, and the kind of flexible thinking our kids will rely on for the rest of their lives.

I hope you'll read it — and I'd love to hear your thoughts and your family's story.

When Spring Hits the Skin

Spring should feel like a fresh start — but for kids with eczema, allergies, or asthma, it often feels like the hard season just changed its name. The pollen, the schedule shifts, the extra time outdoors: it all lands on an immune system that has been working overtime since October.

In this month's article, we break down why spring tends to bring flares — and, more importantly, what actually helps. Not just symptom management, but the bigger picture: sleep, nutrition, the gut-immune connection, and the environmental adjustments that reduce the load on your child's system before it gets overwhelming.

In this article Dr. Hertz explores how Zest’s Core Values are demonstrated by Olympians and what the Olympic spirit can teach us about excellence, respect, and guiding children through differences in a divided world.

Movement as Medicine: Why Spring Is the Right Time to Reset

As winter stretches on, many families notice a quiet shift at home. Kids seem restless yet tired. Sleep feels off. Moods are more fragile. After months of shorter days, less outdoor time, and disrupted routines, children’s brains and bodies are simply out of rhythm.

This month’s blog explores an often-overlooked reset: movement — not intense exercise or packed sports schedules, but the steady, everyday movement that helps regulate mood, sleep, focus, and emotional resilience. As we move toward spring, small, consistent changes can help kids feel more balanced again — physically and emotionally.
