My expertise lies in Lifelong Learning and Human Resource Management. As a professional Wellbeing Advisor, I have collaborated with HR on change management, wellbeing initiatives, and strategic programs since 2004. My experience spans various sectors, including law and national museums and galleries, giving me a broad understanding of working with diverse individuals.

I hold a degree in Psychology, a Master’s in Human Resource Management, a Level 3 qualification in Education and Training, certification as a Mental Health First Aid trainer, and a certificate in Mindfulness-Based Cognitive Behavioural Therapy.

Passionate about holistic wellbeing and workplace health, I am the founder and Managing Director of Greentree Wellbeing.

Hi, I’m Diane. I qualified as a wellbeing coach in 2017 with Raw Horizons and ran my own business for 5 years. In that time, I supported clients both 1:1 and in online group programmes. I also published “The Little Book of Active Wellbeing”, which describes my philosophy on exercise for mental wellbeing, as well as providing advice on building motivation. In 2022, I went back to corporate work, I still speak at neurodiversity support groups and I continue to use my coaching skills when managing my work team.

Hi, I’m Beth, founder of Meraki Mindset by Beth.

As a Holistic Wellbeing Life Coach, I trained with Raw Horizons in 2018—and I haven’t looked back since.

Through the power of self-compassion, I support people pleasers, perfectionists, and those experiencing burnout—people who sense deep down that life is meant for more than just mediocrity and merely ‘getting by.’ I help them step away from the endless cycle, reframe their mindset, overcome self-doubt, and uncover a deep sense of inner peace—allowing them to build a balanced and fulfilling life that truly aligns with them.

If you’re feeling stuck or unfulfilled, I use mindset coaching strategies to help you break free from simply ‘going through the motions.’ Together, we’ll reconnect you with your authentic self, elevate your well-being, and create the harmony you need to ThRiVe and embrace an abundant life—because life is meant to be lived to the fullest.

I graduated from Southampton University with a Psychology degree and completed postgraduate studies in education, followed by a research master’s at the University of East Anglia. My national and international career in education spans all levels of the system. I began as an EYFS teacher, taught the full primary range, and later held various LA advisory roles. In 2005, the DfE appointed me as a regional and National Director for primary literacy in England.

After the National Strategies period, I became an LA Director of Learning, overseeing school improvement for 350 schools. Now, through my consultancy, I work with UNICEF, the National Literacy Trust, and headteachers across the UK. Recognising the challenges in education, I trained as a wellbeing coach, developing ‘The Achieving Balance Model’ to help education leaders sustain resilience while ensuring the best outcomes for children.

Nel Mathams

I’m a consultant, coach, and facilitator with extensive experience in agile methodologies, design thinking, service design, and user research. I’ve worked with a range of organisations, from private sector companies like Redwood Publishing and NEST Pensions to central government departments and the Government Digital Service (GDS).

My approach creates a welcoming space for exploration and learning, fostering innovation while enhancing team wellbeing. Combining enterprise agile, service experience design, and wellbeing coaching, I use visual and serious play techniques to make engagements immersive and impactful. Whether on an ad hoc project or a freelance research or service design contract, collaboration and co-creation are at the heart of how I work.
