When symptoms persist, answers matter

Too many people live with ongoing symptoms despite normal lab results and standard care. Visits are short. Specialists are siloed. Care often focuses on managing symptoms instead of understanding what’s driving them.


Parsley Health was built to change that experience, by giving clinicians the time, tools, and structure to practice deeper, more personalized medicine.


We believe better outcomes come from asking better questions and empowering expert clinicians to understand a patient's full picture of health.

"We can't wait for the wheels to fall off the wagon to see a doctor. We know that the body can heal. Now's the time to listen to the messages your body is sending you, and to ask for help."

Founder & CEO

A physician-led vision for our care

Parsley Health was founded by Dr. Robin Berzin, MD, who trained at Columbia University and Mount Sinai and saw how fragmented care leaves too many people without real answers.


With Parsley, she built a physician-led medical system that treats the whole person—combining whole-body medicine with clinical rigor, standardized protocols, outcomes tracking, and technology-enabled care.


Today, Dr. Berzin continues to lead Parsley Health as CEO, advancing an innovative model of functional medicine that can reach and impact more people every day.

Progress you can see and feel

We use our proprietary, clinically-validated Parsley Symptom Index (PSI) to track progress in our care. Parsley members complete the PSI before their first visit and periodically over time. Clinicians use it to guide conversations, monitor progress, and understand how changes in care affect quality of life. Nearly 9 out of 10 members report symptom improvement within their first year of care.
