1:1 Bespoke Nutrition & Lifestyle Package

Through an initial consultation, we will explore all areas of your health and lifestyle covering your current symptoms and past health history, dietary habits and daily routines and everything else in between. From this in-depth information and detailed review, I will create a unique programme covering Nutrition and lifestyle advice that may also include supplements or tests if needed. Making changes does not simply happen overnight. It can take time to build up healthy habits and implement changes with long-lasting effects. Therefore I recommend working together for a minimum of 10-12 weeks with weekly or fortnightly support sessions, in order for me to support you on your journey to better health and well-being.


We can discuss your needs beforehand during a free 30-minute call to see if this is the approach you’re looking for to get your health back on track.


Health & Wellness Coaching Package

If you don’t have any major health concerns and are just looking for general support and guidance on your health and well-being then this could be a more suitable and simpler option for you. This would still be 1:1 that runs over a minimum of 6 weeks depending on your needs, which we can discuss in your free 30-minute chat with me.


Health & Fitness Coaching Package

Are you looking to improve your fitness whether you’re a beginner or more advanced? Do you need a sport-specific plan or want to lose fat and build muscle? Are you unsure where to start or anxious about being in the gym? Do you need structure, motivation and accountability? Whatever your goal I provide 1:1 Personal Training, in the gym, at home, or online. Depending on your experience I can create bespoke programmes for you to follow yourself with weekly check-ins to keep your journey on track. With guidance on training and nutrition, I will help you build your confidence, your knowledge, your strength and your fitness. Whatever your fitness goal, I can help you reach it.

What People Say


I am sure that if it wasnt for your classes, the function in my left bicep would have not come back. Also I would have not been able to recover from my chemotherapy so quickly, I can not thank you enough.

I feel like Ive come such a long way since my first session with you and I just wanted to express my gratitude to you for the treatments and advice youve given me Thank you Ben!!!

I had four Bowen sessions each about three weeks apart, after the first session I felt a notable difference in my posture and in the strength of my spine, strangely I felt taller. By the fourth session I knew that my discomfort had been resolved and I am now able to move much more freely and flexibly without worrying about my back.

I would definitely recommend Fran to anyone who is looking for a little guidance. Fran is very warm and so easy to talk to. Even online, I was able to instantly connect to Fran, and she really listens and has the ability to help guide without judgement. I'm grateful for the work she has done for me

Got an appointment through really quickly. The staff were really friendly and made the procedures and testing easy to understand throughout, step by step. Really pleased with the outcome. Finally got the answers I was looking for and would highly recommend.

Great service from Ben and his team. If you want your aches and pains sorting out or if you feel your life just isn't in balance you really should give Integral Health a try...

Had several neuro-energetic kinesiology appointments at the Centre and found the experience to be very beneficial and eye-opening. Would recommend to anyone. 5 star

Working with Fran over the last few months has been a joy. I loved the variety in our sessions. Many different techniques always resulting in breakthroughs that Fran then helped me to process. Thanks again!

I'd also like to say that the appointments I have had with you have made such a big difference to my life. Although it's been hard cutting things out of my diet, I can't believe how much my skin has improved since my appointment with you. I will continue to recommend you to my family and friends because as I have said, the appointments I have had with you over the years have improved my well-being so much!

I would like to thank Wan, for a deep tissue and stone massage, it's an experience that I've never had before, already booked for next week, I would recommend this to anyone, please look at there website as there are numerous things to do within the complex.

Love the Qigong classes Ben runs. Professional, safe and informative. Thanks Ben

I used the centre to help training and preparation for a marathon. As well as getting some great advice around technique and training, I was also introduced to Bowen Technique which helped repair a slight hamstring injury and also Kinesiology which allowed me to design a bespoke training diet. Would definitely recommend.

I've been working with Ben for just over a year now and have found his support incredibly helpful. Most recently, Ben has taught me specific techniques for managing emotional response and staying calm and in control during moments of extreme pressure. Ben's walk and talk sessions are fantastic and I would highly recommend him!

So I cant quite believe Im writing this a week on but his legs seem nearly cleared, hes now not drinking any milk.... he eats more in one meal than he did all day and I dont want to speak to soon but 2 nights now he has slept through.compared to waking under every 2 hours the last few weeks. ...in one small week our lives seem much improved!

I highly recommend the Centre for Integral Health. I've been here for multiple sessions with Ben Calder, and honestly, you need to go and experience it for yourself. Friendly, professional and just a generally positive experience all around! The Centre offers such a range of services, I can't wait to try out a few of the other therapies they offer!

10 days after the session for my daughter, she received a "Heart Award" at school for her positivity. She has been bright, positive and done after school activities - clubs and sports 4/5 evenings! She wouldn't even leave the house unless 100% required a few weeks back. I thought I should share this with you. Thank you.

"I really struggle to meditate. To sit in silence and with my own thoughts. I had a huge fear of being alone before I met Fran. I wanted to calm my thoughts when I was struggling. Fran recorded an audio that I listen to when I feel myself spiralling down into my negative emotions. It helps me to remember that I'm never alone and I can listen to it wherever I am. Thanks so much Fran!

"Working with Fran over the last few months has been a joy. I loved the variety in our sessions. Many different techniques always resulting in breakthroughs that Fran then helped me to process. Thanks again!

Wow! As I left my session with the amazingly knowledgeable Ben Calder I said: I feel lighter! I feel so light because I now know what my body does and does not like. I cannot stop talking to everyone about how amazing Ben is! Everyone should go and see him! What an amazing soul Ben is! Super grateful that our lives crossed

Went there yesterday for my first yoga session. It's a great little place. Didn't know it was there until a few months ago. I also go there often to have a massage which I love!

Before I had a series of Bowen sessions I had lived with lower back pain and discomfort for over ten years. I chose the Bowen technique as I wanted to be treated by a practitioner who understood that the body is a whole system. The technique itself is not invasive or stressful on the body as the underlying approach is that with the right support, time and gentle encouragement the body can heal.

Went very well. Was very happy with how friendly and welcoming it all was, and the treatment was at the highest quality.

I was very impressed by the service from Integral Health. I was contacted and offered an appointment immediately after contacting the centre. Ben Calder gave me excellent advice and managed to sort out my issues in only one session.I would highly recommend this clinic.
