Our mission is to help millions back to good mental health

Our story

The idea for Big Health was born when co-founder Peter Hames had trouble getting anything other than medication for his insomnia. He discovered Dr. Colin Espie’s book on cognitive behavioral therapy (CBT) for insomnia, and realized what had worked for him could work for millions. Dr. Espie then became Peter’s co-founder, and together they created Big Health and its mission: to help millions back to good mental health.
