Progress you can see and feel
We use our proprietary Parsley Symptom Index (PSI), originally developed by Dr. Robin Berzin, 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.
