Mark Tyrrell and Roger Elliott, sharing Uncommon Knowledge since 1998

Mark Tyrrell & Roger ElliottUncommon Knowledge was born from a desire to provide sensible psychology to people with everyday mental health issues such as anxiety, panic attacks and depression. Over the decades this mission has evolved from in-person training and printed newsletters through CDs and iPods, to apps and online training and multi-channel social media, all the while empowering people to manage their own minds.

From helping tens, then, hundreds, then thousands of people in the UK, Uncommon Knowledge now supports hundreds of thousands across the world and to date well over a million people have used our hypnosis downloads.

Uncommon Knowledge aims to serve two audiences - professional therapists and the everyday person - all underpinned by a strong belief in common sense psychology. We base our approach on the understanding that human beings everywhere have a set of 'primal human needs' which when unmet lead to psychological and physical problems.

Sensible psychology underpins all we do.

Why Uncommon Hypnosis is different:


Uncommon Knowledge: The origin story

1994-1995: A Meeting of Minds

  • After training in hypnotherapy, Mark runs his first self-hypnosis workshop in 1994, igniting a passion for hypnosis that would shape his future.

  • In 1995, Mark (already building his therapy business) meets Roger (an engineering graduate with a knack for communication and marketing) at a charity fundraising company where they both work. This meeting sparks a friendship and a business partnership that will lead to the creation of Uncommon Knowledge.

  • Roger joins Mark running hypnosis workshops and they spend many a weekend on the road travelling around England distributing marketing materials and presenting the workshops.

  • Mark and Roger move on to working with Mark's father, Ivan Tyrrell, at MindFields Seminars, a psychology trainer to the NHS and Social Services in the UK (now named Human Givens College).

1998: Uncommon Knowledge is Born

  • Mark and Roger officially establish Uncommon Knowledge Ltd in Brighton, UK, with the mission to provide practical psychological tools to address mental health issues like anxiety, panic attacks, and depression.

  • They continue running their in-person training hypnosis workshops, laying the foundation for what will eventually become a global enterprise.

1999: First Diploma and Newsletter

  • The first Uncommon Knowledge Diploma in Solution-Focused Hypnotherapy and Psychotherapy is launched, setting a new standard for professional hypnotherapy training in the UK.

The quarterly print newsletter, which would later evolve into the Clear Thinking email newsletter, is created to keep in touch with course graduates.

  • The first Uncommon Knowledge website goes live, offering a mix of psychology articles, training courses, and self-help audio products. This marks the beginning of their online presence and is followed by a range of other small, topic-focused websites.

2003: Launches

  • Inspired by a chance conversation while touring New Zealand with his wife, Roger records the first hypnosis audio sessions in Wellington, NZ. This leads to the launch of Hypnosis

  • Meanwhile in the UK (now in city centre offices in Brighton with therapy treatment rooms and staff), Mark was having an epiphany after a session with a client: "Why limit yourself?" asked the client, a successful businessman. "Think big, Mark! Why only see eight people a week when you can teach one hundred, a thousand others to do what you do who could, in turn, each see eight troubled souls a week? 8,000 people a week!"

These were the seeds that germinated into flowering motivation, possibility and action, and so Mark and Roger set what felt like a huge goal to create 100 downloadable hypnosis audio sessions, and the site where you're reading this, Hypnosis, was launched in 2003. There are now more than 1300 sessions on the site.

  • The Growth Zone membership area is introduced, providing subscribers with ongoing access to new content and resources.

Our Philosophy and Ethics

Sensible Psychology for All

Sensible Psychology Dictionary logoAt Uncommon Knowledge, we believe in common-sense psychology, addressing primal human needs to prevent psychological and physical issues. Our methods combine scientific understanding with practical applications based on experience, ensuring our products are both effective and ethical.

Our Unique Approach

We use 'uncommon hypnosis,' a method that blends hypnosis with storytelling, metaphors, and analogies as we believe this is the most effective way to communicate with the unconscious mind. This approach sets us apart from traditional hypnosis methods, making our sessions relatable, impactful and usable by everyone.

  • We're in full control of what we do, there are no shareholders or investors driving the agenda. This has its downsides in that we have to develop our technology ourselves but you can be assured that our focus is fully on the quality of our product.
  • We don't use hired or AI voices, only Mark and Roger will do it for us!
  • We don't tend to pursue fame or publicity (although that's perhaps because we're a bit too British when it comes to that!). Because of this we rely on our customers to spread the word - thank you.
  • Every script is brainstormed by Mark, Roger and Joe and written from scratch, we don't have standard passages that we copy and paste. Each session is conceived, created and delivered with the customer in mind.
