My Story

I have been in clinical practice since 2001.  Before I qualified in Nutritional Therapy and later  Homeopathy, I was beavering away in a laboratory as a research scientist. 


My educational background is rich in the traditional sciences. I have a habit of collecting letters after my name, it just seems to be a bi-product of my life . I have a BSc in Pharmacology, MSc in Molecular Toxicology and Pathology, PhD in oncology from King’s College, London. 


When I thought that was it, I dived into the world of ‘food as medicine’, what some call ‘alternative medicine’ and completed a MS in Clinical Nutrition in the USA. WOW! It was ‘eye opening’. How was I not taught this during my under-grad studies? I sat with medics during my BSc and yet no mention of food, how was that possible when we were being taught about drugs (medication may I add), when there is plenty of science to show nutrition is a powerful form of medicine? Why not have nutrition as a core subject in these ‘health science’ degrees?  As they say 'good nutrition is medicine, bad nutrition needs medicine'. 


I later studied homeopathy in London and now I teach what I love.  I have been teaching since 2002, from biochemistry, naturopathy, nutrition, and at one point I taught science to home educated children whilst my boys were also home educated.

I am an avid learner and I integrate the newest research in the science of nutrition into my lectures. I take teaching very seriously and I spend a lot of time preparing my lectures. Some have said, ‘I have the gift of making complex topics not only more easy to understand but inspiring’.  My passion is not only seeing clients empowered and returning back to health,  but also to raise the next generation of practitioners in nutritional medicine who focus not only on nutrition but on the individual who is being 'nurtured'.


I live with 4 wonderful boys (no such thing as 'oestrogen dominance' in this house); my husband and our 2 boys (age 19yr and 15yr)  and our furry boy, our labradoodle, Ravi (age 6yr). 


Dr. Amy Redmond PhD

Psychological Coach

At the heart of my work has always been a desire to help people thrive. Like most people, I’ve travelled a long, meandering road to get to the point where I love doing what I do.

I’ve spent 25 years studying and working in the field of psychology and behaviour. A Bsc in Psychology, and an Msc in Occupational Psychology secured me my first much-loved role as a business psychologist. In that role I learned about the nuances of organisations and saw first-hand how a company’s culture could either support people to thrive or set people up to fail. I saw that everyone held within themselves the power to innovate and thrive but sometimes organisations or circumstance quashed that power. 

This realisation left me with some burning questions about the psychology of innovation. What are the conditions that determine whether people will be successful or fail? In pursuit of answers to this question I enrolled on a PhD programme. After 7 years spent researching the Psychology of Innovation, I passed my viva and was ready to focus my efforts on helping organisations and teams reach their lofty innovation goals. (Yes, 7 years is a very long time, but my kids were very young, and sleep was elusive!). 

Although I was armed with lots of knowledge and experience, something was still missing from my understanding of thriving. In my role as Director of Psychology and Innovation at an innovation agency, I saw that sometimes people were in a position where they had the potential to succeed (i.e. good organisational culture, great skills, determination) but they still struggled to get to where they wanted to be. I saw that people often, unknowingly, hold themselves back from their own success. We carry our past with us and sometimes our past gets in the way of our future. But we DO have the power to overcome whatever is getting in our way, sometimes we just need a little help. This realisation was what led me to refocus my attention on Coaching. 

Coaching enables people to become the best version of themselves and frees them from what’s holding them back so they can create the life for themselves that they truly want. Every time a coaching client has a transformational ‘a-ha’ moment, I know that I’m doing the right thing. I also know the world needs more coaches which is why I love teaching coaching. 

The final piece of my career puzzle is health and nutrition. The links between physical and psychological well-being are well-known and combining coaching with health creates a powerful combination of skills. In teaching coaching I have a couple of core objectives. 1. Enable you to achieve your goals to become an incredible coach and practitioner of nutritional medicine; and, 2. To ensure you can help your future clients to live their best possible lives.

Teaching and training has underscored every stage of my career. Teaching is important to me because I get to share what I’ve learned and what I love. I want everyone I teach to leave with the same love of coaching as well as the skills they’ll need to thrive as coaches. 

Meanwhile, at home these days, sleep is less elusive. My two lovely children are fast approaching teenage years and I delight in having to wake them up in the mornings. Oh, how the tables have turned! We live in the beautiful Chilterns with a menagerie of fluffy friends - our dog Georgia, and too many cats to name – waifs and strays that we’ve acquired on our travels. As well as, I kid you not, our rescue gecko…but that’s a story for another time. 

Debbie Fisher

Executive Coach

I am a qualified Executive Coach and Mentor and Team Coach, with a background in organisational change and leadership development. I work in the UK and globally across the public and private sector, such as the NHS, councils, charities, universities to name a few.


I believe all people have an innate ability to fulfil their potential and this can be accelerated with the right support. I coach because deeply listening, supporting and prompting new awareness helps people find the answers that unlock their true potential.  Coaching allows us to share a safe space where we can express our thoughts and feelings, held in the safety of a professional who can help you effectively navigate your unique territory. 


I love to work with individuals and teams who share my belief that we are all sitting on innate wisdom we just can’t always grasp it. Sometimes we need to give ourselves the time and the headspace to pause, reflect, explore so we can move forwards. We then leverage this newly acquired knowledge and insight to propel you and/or your team into top performance.


When you need to have stretching or challenging conversations with your team or with yourself, don’t underestimate the power of expert facilitation to coach you through to reach a better place. Time to have those ‘elephant in the room’ conversations? If not now, then when!


I consider myself to be a professional balancer of patience and pushiness, listening and prodding, accelerating and braking, managing the dynamics to gain higher perspective, clarity & simplicity, and finding the agency to up your game.


Be the best you can be. (PS sometimes it’s actually about getting out of your own way!)

Lisa Strbac

Homeopathic Practitioner | Integrative Nutrition Health Coach

My journey towards holistic health started in 2015 after witnessing the power of homeopathy, nutrition and lifestyle changes to heal my then 5 year old daughter's chronic autoimmune condition. I was a previous sceptic but I had exhausted all conventional approaches. 


Witnessing the power of these healing modalities in my daughter, I went onto qualify as a homeopathic practitioner and an Integrative Nutrition Health Coach. 


I have always had an innate passion for understanding people which had led me to study Psychology at UCL where I obtained a 1st class Honours degree prior to having my girls. 


As I started my clinical practice, I observed that the clients who progressed the most were those that were also willing to look at various aspects of their lives. It is not just the food on our plate (secondary foods), or the ‘magic homeopathy pill’  that makes an individual healthy but also the primary foods such as relationships, community, sense of purpose, physical activity and spirituality which are just as important as the food we eat and in some cases more important. How are your primary foods? 


My main passion is to empower individuals to take responsibility for their own health with the understanding that true health comes from within. 


I have a podcast, Raw Health Rebel, which explores natural healing and empowers listeners with the message that true healing comes from within. 


As I see my client’s health transform using the various modalities, my ‘work’ has evolved to teaching individuals on how to use homeopathy at home. If every individual had a basic homeopathy kit and knew how to use it, the world would be a very different place. 


I am so excited to be part of the teaching team at the New School of Nutritional Medicine. 


I live in my original hometown, East Grinstead, West Sussex, with my husband, our two daughters (now 7 and 11 years old) and our elderly Cocker Spaniel furbaby, Daisy dog.

Keri Williams Profile

Keri Williams

Life Coach & Naturopath

Hi! I'm Keri and I am a certified life and weight loss coach. 


I help women find peace with food and their body after a lifetime of overeating, emotional eating, chronic dieting, and let’s not forget all the food guilt and body shame! 


I use a combination of coaching, EFT (Emotional Freedom Techniques) tapping and nutritional teaching to help women release unconscious eating patterns and emotional attachments to food. 


I support clients in discovering trust in their body and the foods they eat by aiding them to understand how the brain is wired to work around food and why humans naturally overeat. 


As a life and weight loss coach supporting women in achieving their health goals also means helping them in releasing emotional stress held from the past that may be contributing to emotional eating patterns. 


Rather than prescribing yet another diet or eating plan, my unique approach is helping clients to find their own ‘forever plan’ while releasing long-held emotions, so clients can create a maintenance mindset that lasts and never diet again. 


I have a private coaching practice where I  see clients from all over the world online. I am also Co-Host of the Weight Loss for Life Podcast and the Co-Founder of The School of Sustainable Weight Loss. 


Before transitioning into coaching, I practised holistic therapies and also hold certifications in homeopathy, naturopathic iridology, and kinesiology.


Outside of this I am a mama to my baby daughter Maia, and fiance to 'Frenchy' the amazing chef. We live with two crazy cats in London and you can find me doing yoga whenever I am able to get on my mat!


Sally Beaton

Women's Holistic Nutritionist and Coach

I’m Sally and I’m a women’s holistic nutritionist, life-coach, author of ‘Get Your Sparkle Back’ and founder of ‘Women With Sparkle’.


Put simply, I love life, I love people and I believe that everyone deserves to live with vibrant mental and physical health. I’m passionate about people understanding how their body and mind works so they can reach their goals in life and be who they came here to be.


I know first-hand the power of nutrition, homeopathy and coaching to transform someone’s life after I struggled with ill health for over a decade.  After working in the music industry, PR and charity sectors, a move to Switzerland in my thirties enabled me to retrain in my newfound passions of health and coaching at the School of Natural Health Sciences. I now have the privilege of coaching clients all over the world to help them achieve more than they ever thought was possible with regards to their health and happiness.


I believe that coaching is vital when helping people to make changes to their diets and vice versa. I’ve seen in my own online practice how the combination of these two things helps make some of the greatest transformations in people’s lives. Nothing makes me happier than seeing a person who’d given up on themselves (or been given up on by others) reclaim their health, power and joy through a better mindset and diet.


I have a special interest in women’s hormones and my book ‘Get Your Sparkle Back’ has been called “Life-changing” and a “Must read for all women”. I also run ‘Sparkle School’ where I, or a guest teacher, host a monthly online Masterclass with the aim of helping women to reclaim their health, power and joy.


I can't wait to spend time with you at the New School of Nutritional Medicine because I know this life holds so much more for you (and your future clients) than you might’ve believed or been taught was possible. 


Outside of work, I enjoy living close to the river in Oxfordshire so I can roller skate along the towpath; have daily doses of nature’s medicine and meet all the dogs out for their walks.


Gemma Boxall

School Coordinator

I studied Nutrition and Homeopathy in London, qualifying 2021. The course taught me how diet impacts upon our mental and physical wellbeing, empowering me to make healthier decisions whilst also taking care of those close to me.


I am really excited to be a part of this new School, Khush teaches in such a straightforward way with passion which makes some difficult subjects really easy to absorb. 


Many years of being an Executive PA have given me the experience to support individuals with my efficient personal and organisational skills. As the School Coordinator, I am here to provide you with administration support and guidance during your studies.


I live in the beautiful Cotswolds with my cat, Miffy.

Looking forward to meeting you soon!

Alenka Kostiviarova

Integrative Nutrition Health Coach

Hi, I’m Alenka and I will be your student coach, your ‘friend on the phone/zoom’. I will support you during your journey to becoming an Integrated Nutritional Therapy Practitioner.

As a child of herbs, coming from a country where there is a herbal tea for almost every ailment, and and food was eaten by the season, growing up I was always connected to a holistic approach in health and life itself.

I studied Landscape Architecture and worked with children as a nanny when I was introduced to the world of Homeopathy and Integrative Nutrition coaching. This helped me to see life in a different light, I now understood that the food I eat, thoughts I think, people I surround myself with, my work, my beliefs, my feelings, joy, money, my relationships, they are all connected.

I take clients on a metamorphosis journey to connect with themselves and listen to their own body. With tools like Hair Tissue Mineral Analysis, potentised herbs, tissue/cell salts and energy healing I help clients create their own ‘magic’ in their lives.

Having been a student as an undergrad, post grad and ongoing studies and running my own coaching business, I value the importance of having support, and appreciate having an accountability ‘buddy’ who can guide me on my life journey and respect my unique approach in my health and life rather than tell me what to do (or not to do).

I enjoy helping others succeed.  I coach individuals in building their businesses and creating their unique voice and presence online and in person.

I live between London and Slovakia with my partner and daughter, enjoying the beauty of both worlds, I enjoy travelling, nature and family.
