Fox Chapel, Pittsburgh

When your child is sick, who’s really there?

At 11pm, when the fever spikes, most parents discover the difference between a pediatric office and a pediatrician who truly knows their child.

Most parents don’t realize what’s missing — until they need help most.

In traditional pediatric practices, after-hours care usually means:

• A nurse triage line
• An on-call doctor who doesn’t know your child
• Waiting, worrying, or guessing what to do next

That may be common. But it doesn’t have to be normal.

Zest was built for families who want direct access, real relationships, and calm guidance when it actually matters.


Meet your Fox Chapel Zest Pediatrician

Dr. Hayley Hellstern is a board-certified pediatrician serving families in Fox Chapel and the greater Pittsburgh area.

At Zest, Hayley cares for a small panel of patients, which means:

  • She knows your child

  • She knows your family

  • And when you reach out, you’re reaching her, directly

This allows pediatric care to feel personal again — the way it was meant to be.
