What our customers say about us: 


I came to Diana with a long term Sinus problem which she helped me eliminate in a short period of six weeks. It has been gone forever. The simple breathing techniques work and Diana helped customise it to fit my busy lifestyle. Her compassionate and practical guidance has been a blessing.

I hired Diana for assistance with stress reduction in the workplace. She’s very knowledgeable and her breathing exercises worked very well. I could readily see Diana assisting people with anxiety and depression disorders; as an alternative therapy to medication; being mindful of one’s breathing.

I met Diana at one of the professional development programs. Since then we worked together on numerous occasions. I watched her grow programs and breathing courses over years and also hired Diana to deliver training to my team. Recently, I also had an opportunity to watch Diana presenting at the Laughter and Wellbeing Conference 2020. She was absolutely brilliant. Diana presented on the importance of a healthy respiratory system and it's relationship to Laughter Yoga and general well-being. She is an amazing professional and I highly recommend getting in touch with her

I have been working with Diana for over 3 months now, after understanding that breathing through my mouth was not a good thing for my body. It was a matter of getting the training started for me to see the difference in my energy levels, better sleeping nights with proper rest and after a couple of months discussing with my GP how my lungs had gotten stronger, not that we had thought they were weak. Now I am very self aware of when my mouth tries to do the work for my nose and I get to fix it on the moment. There is no need to wait until you are sick, to learn about your breathing habits and how to improve them. Thanks Diana for your amazing guidance.

I am glad I participated in the Oxygen Advantage program with Diana. Within few weeks I’ve learnt how to breathe correctly, and as an active person I’ve noticed better recovery time after strength and conditioning workout (burpees ect.) I have quality sleep now (I wake up more refreshed than before the course). I recommend that program to everyone working out.

Diana has deep knowledge of breathing methods that she teaches to groups and individuals. I was lucky to attend one of her sessions on diaphragmatic breathing and it was very insightful and pragmatic. I slept amazingly well afterwards
