Meet the team

Sglein is all about helping you and your staff shine at what you do!

Huw Thomas - Partner

Huw’s passion is listening and communicating with others, building rapport and helping people develop. Huw set up Sglein in 2005 with Sarah Mair as there was a need for engaging, motivational learning that has an impact on individuals and their organisations. Huw brings a sense of adventure and energy to every session and can facilitate in Welsh, English and bilingually. Transforming people’s experience of learning and development brings him great satisfaction and engaging with people on an individual and group basis is something he thrives on.

When not working, Huw enjoys running, cycling and mountaineering. He loves pushing and challenging himself and has completed several half-marathons and marathons, cycled long-distance in Ireland and has climbed and travelled extensively in the UK and further afield. These activities give Huw a sense of achievement, perspective and connection with people, cultures and places in a meaningful and memorable way.

Sarah Mair - Partner

Sarah’s passion is seeing others develop, learn and enjoy the journey. She set up Sglein, with Huw, to make a real difference to the way we learn in Wales, not only through being able to facilitate bilingually but through transforming training into enjoyable and experiential learning. Sarah loves the challenge of creating innovative training which makes a real difference to participant engagement and to the business.

Often described as sparkling and dynamic, Sarah loves life and believes in making the most of every day.  Sarah set up and leads a rock and pop ladies’ choir ‘The Phil Harmonics’ and over the last five years they have performed all over the UK and have raised thousands of pounds for various charities.  Sarah lives with her husband and two cats and has two children, who have both flown the nest.  When she does have some spare time Sarah enjoys gardening, walking and baking.
