Liz Ashall-Payne, Founding CEO

As an NHS speech and language therapist, Liz was frustrated she could only see one patient at a time, especially with such long waiting times. This led her on a mission to improve quality and efficiencies within NHS departments. With the advent of healthcare apps, Liz set up ORCHA, the world’s first health app rating system. Her objective: that professionals and citizens should have access to health apps they can trust.
