Who are we?
We’re Trevor and Rebecca Silvester, a husband and wife team who formed The Quest Institute in 2001, originally to promote the use of Cognitive Hypnotherapy and NLP for people with serious illness.
Along the way we evolved into something broader by recognising that we could bring the benefits of our approach to a much wider audience by training competent and ethical practitioners, and supporting them as they built their practices.
We were Police Officers for many years before finding a fascinating new way of helping people. While trainers at the Metropolitan Police Training School in Hendon, we pioneered the use of NLP and hypnosis in a unit dedicated to improving the performance of students who were failing their training. Over a three year period we developed a learning system based on NLP principles that could guarantee an improvement of 10-30% with only two and a half hours of coaching. Simultaneously I (Trevor) was establishing a hypnotherapy clinic that I ran in the evenings and weekends – a busy three years!
I discovered that many of the principles I’d developed with students who were scared of exams or had poor study skills, applied just as much to members of the public with a wide variety of presenting problems – and that they could be helped quickly too. Often it comes down to us not understanding how our brains work, and how to help them work better, so we’re often left at the mercy of a mental programme that runs for a positive reason, but with a negative effect. I believe that all such programmes, from smoking to phobias, to anxiety disorders, to confidence issues can all be changed. From this emerged the approach we’ve come to call Cognitive Hypnotherapy.
When it came time for me to return to street duties we decided to plough a different furrow. I resigned and ran a full-time practice, as well as being brought in by several hypnotherapy schools to teach elements that I’d gained a reputation for – hypnotic language and the use of regression. Three years later Rebecca joined me and we launched Quest. We were very keen to teach a cognitive hypnotherapy course that we completely believed in, uncluttered by the tradition and dogma that I found abounded in hypnotherapy training.
We both felt there was a niche for mainstream people who wanted to train in a modern approach to hypnotherapy based on sound science. We also felt that the public wanted to go to see those kinds of people too. We’ve been proven right on both counts. We attract students from a wide range of backgrounds who attract clients from a wide range of backgrounds, and we invest our time in helping them after graduation because it’s fun to see them build something they love and believe in, and also because they’re a great advert for us. In so many ways Quest is now much more than the two of us.
We hope you can tell that the principle of service is important to us. Our mission statement has become:
“Serving the public by creating a network of ethical and competent practitioners of Cognitive Hypnotherapy. Serving our students and members by providing cutting edge training and quality support”.
We’re committed to the evolution of Cognitive Hypnotherapy as a source of health, personal empowerment and a greater understanding of human potential. Through the provision of a professional and competent service to the public we also aim to achieve ethical prosperity for all our members.

“I don’t stand at the front of the room because I’ve found all the answers. I’m there because I’m passionate about the search for them.”

Bex Silvester
Operations Director
Rebecca Silvester is an NLP Master Practitioner and Cognitive Hypnotherapist with many years experience in the training field. What her title really means is that it’s her organisational and people skills that keep Quest working. Don’t bother asking Trevor anything about dates, money, or planning, it’s Rebecca who’ll have the answer.
In addition to her role within Quest, Bex was formerly a member of the UKCHO (United Kingdom Confederation of Hypnotherapy Organisations) comittee, in her capacity as chair of that organisation’s training schools sub-committee, which assisted and advised on developing training standards and policy.

Jan Gilbertson
Office Manager
Jan Gilbertson is Rebecca’s right hand woman as well as being a practising Cognitive Hypnotherapist serving the Newmarket area. Jan is a graduate of Quest so can also offer a personal perspective on the training.

Julie Gibbs
Qualification Support
We know that taking exams can be a trial for many people so, in addition to the support offered by Trevor and Rebecca we also have Julie Gibbs. Julie is another Quest graduate with a practice in South London. Julie is available for guidance about the preparation of the Hypnotherapy Practitioner Diploma and has an email contact button in the website’s student area. She also runs two evening clinics on module 5 and module 8 weekends so she can answer any questions students may have.

Barney
Hospitality Director
Barney was a legend within Quest. He was there at the beginning and played an active part in our success all throughout the noughties, including being the means by which several Quest students lost their dog phobias (plus using some of the techniques we teach, obviously).He had a wonderful gift for making people love him and we were bereft when he passed on in November 2010. To be honest, we couldn’t bear to take him off the page, so think of this as an ‘About Us’ page, past and present.
Hospitality Trainees
Anyone who follows my blog will know that, following the loss of Barney we brought Wilma, an adorable miniature Schnauzer into the company. Unfortunately we lost her after a year owing to a brain disease. Yet as one door closed somehow two more opened and we ended that same year with Fred and Betty (yes, we have pretty much exhausted the Flintstones theme now). Fred is the one with the attitude, Betty the obviously patient older sister. They have proven themselves too fond of ripping up paper for admin to be a career path, so we’re hoping that hospitality proves their forte.
