About Us

Dan Collinson & Lesley Lyle – Positive Psychology Learning directors.

Dan and Lesley are both MSc Applied Positive Psychology graduates from the first cohort of the MAPP programme at Bucks New University, High Wycombe, UK. Their interest in different aspects of positive psychology (Dan – Strengths, Lesley – Positive Emotions) and research areas (Dan –  Strength based recruitment, Lesley – Positive Ageing) enables them to offer a broad knowledge set across all areas of the science of positive psychology.

Lesley and Dan ensure that they themselves have applied the interventions that they include in their courses and so are able to highlight the positive impact of them from personal experience. They practice what they teach!

They work together as a team delivering positive psychology courses in association with Bucks New University as well as being Associate Lecturers on the Bucks MAPP programme.

Dan Collinson BSc (Hons) Mathematics, MSc Applied Positive Psychology (MAPP)

Dan has worked for nearly 20 years in the Private (for SMEs, national and multi-national organisations) and Public Sector (working with NHS, central and local government) in roles that have involved consultancy and managing projects and people. He was keen to ensure that his teams had the opportunity to develop themselves, so that they were able to perform at their best, as well as to meet personal and organisational goals. It was this fascination in helping people to be happier and to fulfil their potential that brought him to the field of positive psychology. His work has predominantly been in IT and he has worked in the legal, business travel, financial and consultancy industries.

Throughout his roles, he has been required to coach individuals and run courses. As well as being a certified trainer of NLP and a strengths and resilience coach, Dan is accustomed to designing and implementing courses.

Dan holds a Masters in Applied Positive Psychology (MAPP) from Buckinghamshire New University and was part of the first cohort on the course. Dan centred his research and application on the science of human strengths, goal setting and mindfulness. His current research is looking at implementing a strengths-based recruitment process for disadvantaged young people.
