Our Story
The journey began when Aaron Surtees, Founder and Clinical Director, was first introduced to meditation at the age of 11. While most children were learning their times tables, Aaron was learning how the mind could be calmed, trained, and healed. This early experience sparked a lifelong passion for understanding human behaviour and using the mind as a tool for deep and lasting transformation.
Over the past decades, Aaron and his team at City Hypnosis have helped people overcome trauma, addiction, fears, phobias, imposter syndrome, and deeply ingrained limiting beliefs, supporting clients through some of the most challenging and defining periods of their lives.

Aaron has also worked with a number of high-profile public figures, including Robert Pattinson, Ant McPartlin and Charlie Brooker.
