Hello and Welcome.

My name is Donald Marmara and I call my practice Core Development.

Core Development offers:

  • Individual Counselling and Psychotherapy( face-to-face and phone)
  • Somatic Psychotherapy
  • Counselling and Psychotherapy for Parents and Teenagers(together and separately)
  • Couples Counselling
  • Talks and workshops for groups and organisations

We are wounded in relationship, and we need to heal in relationship. That’s why my aim is to create a relationship within which you feel safe and supported. So you can release unwanted and often unconscious patterns that are preventing you from living your life more fully.

Core Development is an emotional learning process that offers you a unique and innovative approach to Counselling and Psychotherapy in Sydney.

It is based on my in-depth professional training and 40 years’ international experience.

I offer you  the opportunity of exploring all aspects of yourself – body, mind, feelings, relationships, work, assumptions and decisions about life – in a safe and supportive environment.

I encourage you and guide you to translate what you learn into everyday life so you can make your life more fulfilling and enhance the world we live in.

Anxious? Depressed?

Tired and Irritable?

Relationship Problems?

Confused and Frustrated?

Sore Back and Headaches?

Lacking Energy and Enthusiasm?

There Must Be A Better Way!

Life can be difficult sometimes. Many of us experience stress, anxiety, depression, addictions, frustration or relationship difficulties.

It’s important to know that this does not necessarily mean that there is something wrong with you or that you are mentally ill.

These are all symptoms. You need to get to the underlying cause to create lasting and meaningful change.

You do not have to be mentally ill to benefit from this approach.

These feelings often arise because you do not fit into any of the boxes that you are expected to fit into. Your needs are not understood and they are not being met.

I’ve been through this myself. I know how it feels. I’ve turned my own life around after many years of distress and helped many others do the same.


I do not look for what’s wrong with you.

I look for what needs to happen, what’s trying to emerge, what your next step needs to be, and how I can support you in taking that step.

My aim is to help you deal effectively with the challenges you are facing, so you can make your life and relationships more fulfilling.

I offer sessions for individuals, couples, parents and teenagers, and talks and workshops for groups and organisations.

If you want guidance and support in dealing effectively with life’s challenges, and in being true to yourself in an environment or society that may not always share your priorities and values, call  02 9413 9794 or 0412 178 234.
