About me

My name is Gregorio and I’m a fully qualified and insured Nutritional Therapist, member of British Association for Nutrition and Lifestyle Medicine (BANT) and registered with Complementary & Natural Healthcare Council (CNHC). I was trained in Naturopathic Nutrition at the prestigious College of Naturopathic Medicine in London. I also hold a Postgraduate Certificate in Dietetics and Human Nutrition from the University of Cadiz in Spain.

I have been trained in the principles of Functional Medicine, a science based approach to health and healing that looks at the body as a whole and assesses the underlying causes of symptoms that manifest themselves as disease. Rather than looking at symptoms in isolation, my aim through nutritional therapy, is to support underlying imbalances and address the root cause.

My approach

What I have learned and continue to learn through my training and practice as a Nutritional Therapist is that alternate pathways to health do exist and sometimes it only requires someone to take the time to listen and understand their story in order to piece the jigsaw together. Nutritional Therapy opens many doors in the ways it may benefit a wide variety of conditions and personally I feel privileged to have the opportunity to be able to work within this field. My focus is on long- term health and disease prevention and achieving wellbeing in body, mind and spirit.

Initial consultation

After booking your appointment, a welcome pack will be sent to you via email, including a Health Questionnaire and a 3 Day Diet, which need to be completed before the consultation. During the initial 1 hour consultation, I take a detailed case history, building on the information from the questionnaire. I will ask you specific questions about your current health concerns, symptoms, diagnosis and treatment, medical history, family history, lifestyle, levels of physical activity, use of medication and supplements and diet.

After the Initial Nutrition Assessment, I will evaluate your individual needs and apply the extensive evidence-based of nutritional science to elaborate a personalised, safe and efficient Nutrition and Lifestyle Programme.

You will receive your Nutrition & Lifestyle Plan and Supplement Recommendations by email within 48 hours. This will include:

  • therapeutic food focus explanation, recommending the foods that might be helpful in alleviating your symptoms, also including the foods that may be stopping you from getting better;
  • sample meals and snack ideas;
  • lifestyle suggestions tailored to suit you;
  • supplement recommendations with a 25% client discount.

Initial Consultations fees are £100

Follow-up Consultation

Follow-up consultations are booked in at the end of your initial consultation and last up to 45 minutes. These are used to track your progress, make any required modifications or adaptations and evaluate test results. We usually book a follow-up consultation 4 - 6 weeks after the initial assessment.

Additional follow-ups may be required depending on each personal situation.

Follow-up Consultations fees are £75

I can also carry out consultations via Skype and Home visits.


"I came to Gregorio interested in how a change in diet could further improve my symptoms plus my overall health. The advice given by Gregorio has helped improve my symptoms and also increase my energy throughout the day.

The benefits have been so noticeable that it has been easy to persevere with the changes to my diet."

(Sophia, London)

"I was diagnosed with a medical condition some months ago and sought Greg's guidance on diet. He was extremely professional and thorough in his approach. He was careful to explain why certain foods were better for me than others and was encouraging and positive in his approach. I would highly recommend Greg if you are seeking help with nutrition tailored to your specific needs."

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a nutritionist's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the nutritionist to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.

Wheelchair user access Yes
