Sally Good


Sally originally set up ASSIST as a public health programme in the NHS following the successful RCT. In 2010 she helped to form DECIPHer Impact. Currently the Acting CEO, she has a wealth of knowledge about the programme and the company. Her background in both education, as a teacher, and public health, as a programme manager has given her valuable insights into both commissioning and delivery. A people person through and through, she loves keeping up to date with our customers and stakeholders both in the UK, and lately, overseas as ASSIST is now being piloted in France!

Ashley Pic

 Ashley Lee

Ashley is our Researcher who, in addition to studying for her Masters in psychological research, also investigates potential products for us to take to market. In her spare time, she is passionate about all things foodie as well as being an avid festival-goer. Contact her if you know of any evidence based interventions that may be of interest to us.

Amy Mander


Amy first came to us as an Intern Researcher, having graduated from Bristol University with a Master’s in Social Anthropology. We liked her so much we decided to make her the newest member of the team.

Amy has extensive experience working with young people as a trainer and mentor, in leadership programmes designed to help young people to achieve their potential. As Programme Development Offer, her role included training and material development, as well as the daily running of the office. Following a sabbatical to Australia, and with a trip to China in the pipeline, occasional days aside, it will be September before we are lucky enough to see that smiley face back in the office!

Fenella Dyson

Fenella was one of the two Trial Co-ordinators for the original ASSIST randomised controlled trial from 2001 to 2006 and as such has a wealth of knowledge and understanding of the programme.  Having studied social psychology at undergraduate level and then completed a PhD in mental health with the University of Bristol, Fenella worked as a researcher in health and social care in the Bristol area for 12 years before taking a career break to have children.  Areas of school-based work included smoking prevention, drug education, and healthy schools. Fenella also has experience training volunteers for the Terrence Higgins Trust and teaching at undergraduate and postgraduate level.  As a French speaker, Fenella is helping to develop the reach of ASSIST into Europe and was part of our recent Train the Trainers course in Paris.

Annie Clarke

Annie has over 12 years experience designing and delivering learning solutions across the charity, public and private sector. She has worked as a freelance trainer for 4 years whilst holding roles including Institute of Fundraising and Talent Development Manager at The Children’s Society. As well as delivering Train the Trainers for ASSIST and carrying out quality assurance observations, Annie will also put together bespoke training to meet the broad range of needs and interests of our customers.

Kirsty Johnston


Kirsty Johnston started her career as a secondary school teacher before transferring those skills to the NHS over ten years ago.  Since then, she has held several posts in Public Health coordinating programmes (including ASSIST) and developing resources in tobacco harm reduction, specifically those to reduce the uptake of smoking in young people. When ASSIST was taken up by Scottish Government, we were delighted that Kirsty had moved back to Scotland from Gloucestershire as DECIPHer Impact has been able to benefit from her passion for working with young people and her experience training within public health.

Nicki Davey

Nicki has over 25 years of training experience and believes that we all perform best when our mind is free, our body relaxed, and our creative potential unlocked. She uses imaginative, enjoyable methods to make training lively, fun and colourful, so that people participate more, learn better and are inspired to put their learning into practice. We have been lucky enough to incorporate some of her ideas into our ASSIST training which she has co-facilitated on many occasions, giving her the understanding of the programme she needs to also be part of our quality assurance process.

We have been working with Nicki since 2011 and have enjoyed our own CPD via her company, Saltbox Training & Events.

Lynsey Northall

Lynsey is a qualified trainer who has worked in health and social care for many years. She has delivered the ASSIST programme for many years on behalf of Public Health Wales as well as across the border in Stoke-on-Trent and Herefordshire achieving the highest grade when she was observed as part of our Quality Assurance Framework. Living in North Wales suits her love of the great outdoors and as well as being a mum to two boys, she is also an Assistant Leader at Cubs and plays for her local women’s rugby team!
