Meet the Team

Developing Potential (UK) was set up from a desire to help individuals, teams and organisations to realise and achieve their true potential. How do we do that? We believe that your people are resourceful and creative; that they already know how to make your business perform better. In our experience it’s not a lack of training or skill that stops people from achieving; it’s people’s levels of confidence, motivation and positive relationships. You don’t need to look far to see a change programme that has failed to ask yourself “why, when people have been given the knowledge and skills to be better do we see very little change?”. Using our knowledge, experience and expertise, we deliver inspirational, active, and memorable learning that you can instantly use in both your work and personal life – programmes that create change on a personal level, changing your organisation from the bottom up. We work with a number of specialist associates to deliver high-quality and value-for-money learning experiences.

Dan Barnfield, Director

His career started through working with young people and using the outdoors as a tool for self-discovery and personal development. An experienced trainer, coach and qualified teacher, Dan uses his understanding of experiential education and outdoor learning to provide powerful, fun and relevant learning experiences. His varied experience of working with public, private and voluntary sector organisations and working with young people through to senior management level make him a well-rounded and versatile trainer.

Julia’s assessment of Leadership Potential began in 1997, she has subsequently moved into developing Leaders and managers through training, facilitating workshops, and coaching for individuals and teams. Alongside this she has a track record of designing and delivering assessment and development centres.  Her style is honest and challenging, and she enjoys the opportunity to increase business effectiveness through individual’s realising their own potential and developing self-confidence to succeed. Julia is equally comfortable working in a solutions-focused way that builds on existing behaviours, or, exploring what emerges in a coaching conversation at a deeper level around identity, values and beliefs (including limiting self-beliefs).  It is important for Julia that leaders are authentic and this is a key area of her focus.  Her values of authenticity and competence underpin her work.

A Fellow of the Chartered Institute for Personnel & Development, Julia’s work record spans both the public and private sectors having been a Royal Naval Officer for 10 years, a Civil Servant and an HR consultant operating in international organisations, the private and public sectors.   In her spare time she enjoys eventing her horse Harry and spending time with her family.

Darren has been involved in people development training since 1989. He has a passion for enabling learning and thinking differently.  Darren’s work record spans both the private and public sectors, including time as an Intelligence Analyst working abroad. His leadership training incorporates hard-won personal experiences from Supervisor level to Director level appointments.

Darren believes in designing and delivering training that starts and finishes with listening to the client.

His training offers the choice for people to challenge their own metaphors and how useful they may be in that journey.

He has been privileged to deliver to a wide range of people including adults with special education needs, Blue Chip companies, FE colleges, and voluntary organisations. 

Darren only uses things that work including Emotional Intelligence, Accelerated & Experiential Learning, Neuro-Linguistic Programming (NLP), Stephen Covey’s work, and Lean Manufacturing Techniques to name but a few.

When not working he trains for Ironman triathlons and still wonders what part of his map drives that compulsion!

Jock Andrews
Jock Andrews, Consultant

Jock has been involved in experiential development training since 1986, working as an associate with a number of leading training organisations. A parallel career as a civil engineer led back to training via project management. He has a formidable background of designing and delivering behavioural training in as diverse areas as coaching Olympic coaches, Health & Safety, Stress Management, Phobia treatment and Sexual Health.

Jock’s real passion is for figuring out how people learn, and how they shift their self-limiting beliefs, whether that be about learning to juggle, managing their teams, or getting on better with their families. He takes an irreverent approach to training that uses an eclectic mix of elements from old and new wisdom and theory and isn’t constrained by any particular training ‘ideology’.

Recently, Jock has been involved in developing and running a follow-up to the widely acclaimed ‘Mastery’ personal development course, and has been collaborating on a forthcoming book on ‘demystifying’ Emotional Intelligence.
