Meet the team
Gill Erskine
+ Co-founder & Director
Gill is an experienced communications professional who specialises in making complex ideas clear and human. She has spent her career working at the intersection of health, community, and behaviour change.
Before co-founding WildStrong, Gill founded, scaled, and sold a food production business in Thailand, was Managing Director of a locally grown baby food company in Sierra Leone, and worked in communications for health NGOs across Belgium and the UK.
In 2024, Gill was recognised as one of the UK’s most inspirational and dynamic female entrepreneurs by the f:Entrepreneur #iAlso100 campaign.
Within WildStrong, Gill is often your first point of contact. She facilitates all courses, holds the learning space, and helps you reconnect with your own capabilities—building confidence, curiosity, and a sense that more is possible.
“What I love most is watching confidence spread through a group. People arrive full of doubt, and weeks later they’re helping others, making friends, and trying things they never thought they could. That’s when you see what community really does.”
Andrew Telfer
+ Head Coach
Andrew Telfer is a public health professional and movement coach with a deep belief that movement should be social, achievable, and woven into everyday life. He is particularly passionate about using play, games, and shared challenges to help diverse groups reconnect with movement—whether that’s older adults, families, or people who have felt excluded by traditional fitness spaces.
Andrew has been part of WildStrong since the very early days and is responsible for shaping its Coaching Philosophy. He leads the training and development of WildStrong coaches, helping them design sessions that build confidence, capability, and connection—rather than compliance or perfection.
Andrew holds a Master’s degree in Public Health and has over 18 years’ experience in coaching, personal training, and course development. His professional training includes NSCA Certified Strength and Conditioning Specialist (CSCS), CrossFit Level 2, ACE Certified Personal Trainer, USA Weightlifting (Olympic Weightlifting), and Columbus Weightlifting qualifications, grounding his work in both evidence-based public health and practical, adaptable movement coaching.
In his own words: “I think the fitness industry took a wrong turn when it adopted a top down model of fitness education. I also feel there is too much emphasis on working out alone and the collection of arbitrary data. WildStrong is the opportunity to embed movement in a community setting, with tangible benefits, creating a peer-lead, distributed model of health practice.”
Amelia Foxton
+ Research Partnerships Lead - Nature Moves
As the Research Partnerships Lead for Nature Moves, Amelia helps shape WildStrong’s research strategy and partnerships to explore how movement, nature, and community can support public health and wellbeing.
Before joining WildStrong, she worked as a personal trainer and strength and conditioning coach in Canada, but found her real enthusiasm in outdoor, playful, community-based movement.
Alongside her role at WildStrong, Amelia is pursuing a DPhil at the University of Oxford, researching the ethical dimensions of AI-driven healthcare.
Emily Dean
+ Operations & Admin Lead
Emily is British but has been living in Thailand for 16 years. Her background in both education and fine jewellery spans operations, administration, and supporting people and projects through periods of transition; skills that translate naturally into keeping complex, multi-platform work organised and on track.
Alongside her operations role, Emily has a personal connection to WildStrong’s values through her own movement journey. After years of online, at-home work and a more sedentary phase of life, reconnecting with movement through her own supportive community had a profound impact on both her physical and mental wellbeing. That experience informs how she approaches her role: with an understanding of what it means to balance real life alongside training, learning, and growth.
Sarah Langridge
+ WildStrong Berkhamsted
Sarah has always enjoyed spending time outside, being active and having an adventure, although it’s only in the past few years she has realised how important this is to her.
To manage the stresses of daily life with 2 young daughters and a demanding job, as well as pressures coming from Covid, Sarah turned to regular outdoor activity again. Now looking back, she can see this has been a thread throughout her life and she gains both energy and calmness from it. So she has jumped in for an adventure to set up our Berkhamsted group!
*‘From the moment I found out about WildStrong something sparked within me. The ethos really resonates with me and I am excited to explore what this can bring to people in our area and spend more time doing what I enjoy. I’m looking forward to helping people find the space to find their inner strengths and have fun in the process.
I believe in the power of moving in nature for our whole wellbeing. I know how much benefit I get from this and the WildStrong approach works on so many levels. I love the element of ‘play’ (who doesn’t need that in our full-on adult lives?!) and how it’s balanced with exploring and learning more about how we move whilst getting stronger. I’m learning a great deal about how I move that, despite being pretty active for years, I have never fully understood, and as I get older, I suspect will become even more important!’*
Lynne Ogilvie-Niven
+ WildStrong Falkland
Lynne had an on-off relationship with activity over the years - sometimes just a bit of fun flirting, other-times diving in too quickly and not lasting the distance. Add into the mix a busy life of full-time work and 2 kids, the result is that time for friends, physical activity and getting into the great outdoors are limited.
*"Doing WildStrong lets me be outside, build relationships with people in the local community, use my background in sports development, exercise and wellness, and helps me to move well now and for life.
Like so many of the people who are new to the session, anxieties about not being fit enough to do WildStrong have niggled my head. And yes, the sessions definitely get your heart pumping; but the care and attention that goes into developing the session content, the scaling and alternative movements to accommodate for different abilities, is what has captured my heart. I am wild, I am strong; and you can be too. I look forward to WildStrong-ing with you"*
Megan Badger
+ Co - founder
In January 2023 Megan chose to step back as Director to continue her career as a teacher.
She remains a valuable member of our WildStrong Pangbourne group.
In her own words: *“For me it is all about bringing people together, having fun and getting stronger as we go! I love seeing people’s progress week on week and their confidence grow with it. The camaraderie and support during each session is what keeps us all going even on the coldest and wettest days - exercise is best done with friends after all!” *
Sarah Strang
+ Financial advisor
Sarah has 14 years' experience in professional services, initially focussing on financial and then operational restructuring. Over the last 7 years she has specialised in finance raising for mid market PE-backed and privately owned corporates.
She started working out with the WildStrong team in the very early days, having recently moved to the area. What started out as a simple way to get out of the house and meet some new people soon became a way of life and she has not looked back since.
Andi Straw
+ WildStrong Black Mountains
Andi loves being active in the beautiful countryside close to home. Her working life is split between teaching and community development. She loves to share her passion for learning, helping to support and facilitate the journey of discovery in her communities. Her broad range of interests cover music, including her love of playing in orchestras and bands and all things science related, as well as a deep desire to stay fit and active. She generally has an optimistic outlook on life and is driven by a sense of curiosity and a playful nature.
