Australian Breathwork College Nicholas and Susan

My name is Nicholas de Castella. My wife, Susan, and I are established professional Breathwork Trainers with over 30 years experience. We've built an amazing life through Breathwork.
We are keen to help you create a rich and fulfilling life in service to others.

Our Vision is to Facilitate the Awakening of a New Heart Connected Humanity

We are training Heart Centred, Empathetic Breathwork Coaches to help heal the split between head and heart. Facilitate the integration of mind body, emotion and heart, to come back into relationship with ourselves, each other and the planet so all can thrive.

Learn how to create a wonder-filled life with Breathwork, from people who have done it!

With Breathwork we have raised a family of 4, created an amazing life on our 7 acre retreat centre in the Dandenong Ranges Rainforest on the outskirts of Melbourne.

Our style of Breathwork is Heart Centered, which means it is based on gently connecting, trusting and surrendering to the unfolding that happens in the moment.

Core Clearing Breathwork is a simple yet powerful, gentle yet rapid healing and clearing process to help clients release emotional trauma, open their hearts and gain the clarity, confidence and enthusiasm to move forward and live life fully.

A proven Business, Marketing and Sales System. The training comes complete with a 'plug and play' done for you, resources to attract, enrol and deliver life transformations and build a thriving business as a Breathwork coach or add it to your existing Healing or Coaching Business.

Take clients deeper, help them identify and clear the blockages that are holding them back in their lives. Clients quickly and gently identify and clear the subconscious emotional trauma that cause stress, anxiety, frustration and suffering and connect to their inner guidance for confidence, enthusiasm and direction in life.

Core Clearing Breathwork Coaching utilises Breathwork, Mindfulness, Somatic, Emotional and Heart Intelligence. Our work is a synthesis of 30 years of exploration and integration of Western Science and Eastern Mysticism: Embodiment Practices, Non-dualistic approach, John Bradshaw's Non-shaming Therapy, Buddhist Teachings, Heart Coherence, Vagal Tone and Self & Co-Regulation, Trauma Informed Care and lessons learnt from facilitating over 10,000 sessions.

You can facilitate Core Clearing Breathwork 1 : 1 or in Groups, in person or online with people around the world.

Is now your time to step up and give your gifts, your love to the world?

The world needs more heart-centered leaders to help humanity awaken to the next level of peace, love, connection and aliveness.


I'd be delighted to have a chat with you.

Meet Teresa

"I felt totally destroyed, and fearful as I was wrapped in the chains of havoc even years after the divorce. I then found Passionately Alive it was the first key to setting myself free from the chains holding me in my past and it sparked my own empowerment journey. I began to reclaim areas of myself that I thought were gone forever as I stepped deeper into the training and became a Thrive Breathwork Coach.

I was becoming alive once more and being the positive role model for my children by living and feeling my truth. I now have a clear light shining and directing me in my life (my heart) where once I only saw emptiness and blackness.

Today I am living my heart’s calling; I am saving for the 1st time in 10 years as a single parent, I have my own business; Heart’s Voice and I am a Thrive Breathwork Coach, Women’s Meditation Group Facilitator, Office Assistant and Workshop Assistant with Thrive Breathwork Coach Academy."

Medical Doctors Recommend

Core Clearing Breathwork!


Dr Andrew Horwood G.P

I have known and worked with Nicholas and Susan de Castella for over 10 years. Over 200 of my patients during this time have reported more energy; lessening of physical pain; increased understanding of their life situation; a range of skills that can be used in all sorts of situations to alleviate symptoms of anxiety and depression; improved mood; improved coping skills with life stressors; more passion in their lives, and hence, improved relationships; finding a network of genuine friends from whom they feel support.

Some of my patients attending Seminars have been particularly ill, either physically or mentally, and these patients, too, have been able to make great gains during a short time. I conclude by thoroughly recommending the range of Seminars facilitated by Nicholas & Susan de Castella. These are high quality events with the potential for changing people’s lives forever.


Dr. Margaret Ngu G.P.

As medical doctors you would want to benefit from their transforming work for yourself and of course your patients. I have found Nicholas and Susan to be heartfelt beings who practice what they preach and in doing so have that special quality of authentic and infectious teaching by example. Both are well experienced healing processes, which as a holistic practitioner for more than 25yrs.

I know it as essential for my patients to access in order to regain wellness. Whether facilitated in individual sessions or in groups, patients will get help for the emotional and mental dimensions of their symptoms, which most GPs have no time to delve into, whether it is depression, chronic fatigue, asthma, degenerative illness of all kinds. Your patients will be thankful for Nicholas and Susan's help.


Dr. Peter Johnston G.P.

I have attended Passionately Alive, Manhood and Relationship. I have found them helpful and inspiring. I recommend my patients to attend. In fact I believe emotional and heart centred work is essential for personal growth and healing. I recommend these workshops to anyone with chronic disease, relationship problems, emotional crisis and those wanting to avoid these.

Holistic Medical Practitioner, MBBS (Monash), AMAC (Australian Medical Acupuncture College), FACNEM (Fellow of Australian College of Nutritional and Environmental Medicine), MSE(Psychology), Founder of Australian College of Transformational Medicine. Past President of AIMA, Australasian Integrative Medicine Association (1998-2001)


Dr. Robert Hanner G.P.

I cannot recommend too highly the brilliant work that Nicholas and Susan de Castella do with people who are troubled with life's inevitable challenges and stresses. I had the fortunate experience of doing my first course, Passionately Alive 5 years ago and the benefits I attained have remained to this day. I am more present and, in the moment, and in touch with my emotions since that unforgettable weekend.

This has helped enormously in my personal relationships and in my professional life. Nicholas has created a safe, secure, environment where people are free to express themselves openly. He treats everyone as equals and so even though he is a teacher and facilitator he is neither didactic nor beyond approach.
