My Story

I’ve always been fascinated by how the body can heal itself, given the right tools. However, my fascination began with sheer frustration: I spent years dealing with unexplained abdominal pain so severe it could stop me mid-sentence. Doctors ran tests but found nothing conclusive - I was just offered anti-spasmodic medication. Given my Grandmother’s history of colon cancer, I was uneasy about long-term prescriptions without deeper answers.

My Breakthrough (and Break-up) with Sugar
One day, a radio interview about the book I Quit Sugar sparked an idea: I had previously tried excluding different foods to help symptoms, but never sugar. Determined, I cut out sugar completely, even fruit for a short time. Within days, I experienced flu-like detox symptoms and even an asthma flare - but when I came out the other side, my pain had disappeared. Over the following months, my chronic hay fever and asthma receded too. Amazed, I started listening to podcasts, and then reading widely into functional medicine research, all of which convinced me how critical proper nutrition can be for addressing “root causes.”

Eventually, I saw a functional doctor for some professional guidance, but even they simply gave me a strict exclusion diet that left me feeling a bit lost and overwhelmed. The plan failed to teach me anything I didn’t already know from my own research. I realised that “If I can get so far on my own, what could I do if I was properly qualified?”

I wanted a more complete, supportive approach than I’d received, and thought others deserved this too. This desire to “do it properly” and “do it better” prompted me to enrol at CNELM as they offered a very well-respected MSc degree in Personalised Nutrition.

I was searching for a more complete, holistic way to improve my health and found it in the synergistic combination of nutritional therapy and PEMF.

Exploring Yoga & Overcoming Injury
Unfortunately, not long after my newfound health, a serious bike accident left me with head and tissue injuries that yoga helped me rehabilitate. This spurred me to also train as a yoga teacher, initially just to deepen my own practice, but soon I started teaching small classes and discovering how much I loved helping others move better and feel better.

Discovering PEMF
During lockdown, with in-person yoga on hold, I began searching for at-home methods to boost health and immunity. Because I have asthma, I was especially concerned about protecting myself during a respiratory pandemic. I also wanted to support my family and clients. In my research, Pulsed Electromagnetic Field (PEMF) kept appearing, promising reduced inflammation, deep tissue repair, better circulation, pain relief, and increased energy.

After trial sessions with a high-intensity PEMF machine, I was sold: I slept more deeply, my residual joint and back pain vanished, and I felt clear-headed and more resilient.

I purchased a professional-grade device so I could use it on my whole family, and they all quickly benefited from their sessions. My sons recovered from sports injuries and fatigue much more quickly and their performances improved, my husband’s back issues were resolved, and I even used it on my mother who, in her 80’s, needed a bit of help with her arthritis and energy. Within months I had opened my own PEMFiT Harrogate studio in 2021 to support my clients and local community too.

Creating a “One-Stop Shop” for Wellness
Today, I combine personalised nutrition therapy, mindful movement, and PEMF sessions - under one roof in Harrogate. I want to help others avoid the frustration and despair I felt when there seemed no answer. By focusing on root causes, harnessing non-invasive, transformative tools and empowering coaching, I offer clients a complete path to feeling better - quicker and more effectively than if they tried to patch it all together on their own.
