About Testament Health and Wellness
I’m Tess Thompson, the founder and lead practitioner at Testament Health and Wellness. With a background in Naturopathy, Nutritional Therapy, and Functional Medicine, my approach is both holistic and evidence-based, always aimed at uncovering the root causes of health issues.

I hold diplomas in Naturopathy and Nutritional Therapy from the College of Naturopathic Medicine (CNM), and I am a trained IV Nutritional Therapist and Phlebotomist. My training spans a range of therapeutic modalities, including Herbal Medicine, Functional Medicine, and immune-modulating therapies, enabling me to provide integrative care that supports the body’s ability to heal and function optimally.
I believe true healing comes from understanding the interconnectedness of the body’s systems, not just addressing isolated symptoms. Health is a complex puzzle with many layers to uncover. My goal is to identify the root causes and work alongside you to find sustainable solutions, even when the answers are not immediately clear. I’m here to help you find the missing pieces and unlock the path to better health.
My own journey into integrative health began through deep personal struggle. I spent years navigating chronic illness and immune dysfunction that conventional medicine couldn’t fully explain or resolve. I knew deep down that my health issues must all be connected, but no one could seem to join the dots. I went through the exhausting cycle of collecting diagnosis after diagnosis, without finding real answers or any improvements – despite doing “all the right things.” It was only when I reached a point of complete desperation that I found alternative, integrative approaches – and slowly, began to heal.
As painful as that chapter was, I now see the silver lining. That journey reshaped how I understand the complexities of the body and health on every level. It sparked a deep passion to learn, retrain, and rebuild – and I feel incredibly grateful to have had both the opportunity and the health to pursue this new path. What once felt like an impossible dream became a career I feel profoundly connected to. I never imagined I’d find work so aligned with my personal journey and purpose. Now, I’m doing something I love every single day that feels truly meaningful.
Before retraining in Naturopathy and Nutritional Therapy, I worked as a Special Educational Needs (SEN) teacher, supporting children with complex and additional needs in both the UK and internationally.
My earlier life experiences laid the foundations for everything I do today. My younger sister was born with medical and special needs and truly lit up my life. From an early age, I knew I wanted to work with both children and medicine in some form – two worlds that have beautifully come together in the work I do now.
Today, my approach is informed not only by training and research, but also by lived experience. I understand what it’s like to feel unheard and dismissed when conventional treatments fail, and how overwhelming that can be. That’s why I’m committed to creating a space where you feel respected, supported, and empowered.
One of my particular areas of interest is supporting individuals experiencing chronic immune disorders, including conditions such as tick-borne illness and PANS/PANDAS. Having seen first-hand how under-resourced and misunderstood these conditions are, I’m passionate about bridging that gap and offering integrative, informed, and compassionate care. While this is a key area of specialisation, my training covers all areas of health, with a focus on root causes regardless of the diagnosis. This holistic approach allows Testament Health and Wellness to support a wide range of health concerns, from complex conditions to more everyday challenges.
Outside of my practice, I enjoy cooking, walking, yoga, reading, and spending quality time with my family – my two children, husband, and our dog, Misty. I can lose myself in DIY projects, and ‘pottering,’ especially in the garden, as well as in research, constantly learning and exploring new ideas. My chosen activities shift with the seasons. In the winter, I love cozying up with my family, embracing the quiet and warmth, playing games, and nourishing our souls, especially after a fresh, wintry walk. In the summer months, my absolute favourite season, I relish picnics with fresh, crunchy foods, beach trips, keeping busy, and soaking up the energy of the sun. I’m always drawn to the water, whether on a paddle board in the calm or watching waves on a stormy day, as these moments of connection with nature help clear my mind and soothe my soul.
