hello
I’m Diana, a psychotherapist specialised in all things relationship
The relationship we have with our partners and the relationship we have with ourselves.
No matter where you find yourself right now, I’m here to help.
As a relationship counsellor for over 25 years, I understand that reaching out for help can be hard. Some things feel too personal, too raw – even the thought of discussing them can be confronting. I can assure you that I have worked successfully with many clients who had exactly the same fears when they first contacted me.
Feeling overwhelmed, stuck, or struggling with mental health is so common.
Counselling can help by providing a safe space to talk to someone who really listens, understands and is skilled in providing emotional and practical help. Investing in yourself and putting you first is a big step in creating a better life.
If you’re feeling a little unsure about coming in for an appointment then have a read through this website, it will give you a feel for who I am. Or call me on 0412 466 426 for a 15 minute chat.
No matter what you are facing right now, what I can assure you is that you will be treated with kindness and respect and I will do my utmost to help you.
Let’s work together and make the changes you want and need.
Seeing Diana changed my life. Working through my feelings with Diana has assisted me in discovering and thriving in a loving and fulfilling relationship with my partner. Through Diana I have discovered true happiness and positivity. Diana showed me the person I am capable of being and this in turn has allowed me to be a better romantic partner.

For Couples, Individuals, Employees and their families.
Couples Counselling
Relationship is one of the hardest things we will ever do, yet no one educates us on the skills and perspectives needed to choose the right partner, build a healthy relationship, repair a crisis and maintain the relationship we are in.
The couples that stay together aren’t the ones who never struggle, they’re the ones who choose to consistently put in the work, even on the hard days.
Healthy relationship requires education, commitment and skills. If you are committed, couples counselling provides the training, skills and tools needed to overcome challenges and build the type of relationship satisfaction that leads to a happy long life together.

Relationship counsellor specialising in
Surviving infidelity
Infidelity is shattering, the pain is indescribable. But it is possible to recover, evolve and even thrive. Following a clear evidence-based approach, you will reach a place where you feel confident to make the decision to leave or rebuild.
Sex Therapy
Couples often have differing sexual needs, which can lead to frustration, anger and resentment. Routine and stress replace desire and excitement. The good news is a satisfying sex life can be created through sex therapy fostering genuine understanding, open communication and prioritising.
Do I stay or walk away?
Having doubts in a relationship is normal, it helps couples grow and question their future positively. But there are many reasons that may cause you to consider leaving. Together we will acknowledge your pain, identify your fears and concerns, and assess relationship patterns. Deeper clarity and new perspective will help you decide with conviction.
Conflict Resolution
Any two people who come together will experience conflict. Whether they speak it out loud or suppress their emotions. Relationship counselling shines awareness on how we can operate better. Together we will work on managing conflict in ways that are timely, respectful and fair.
Communication
The inescapable fact is that communication is everything. But it’s almost never about what you are arguing about. It’s about the underlying need that is seeking to be met. It’s a scientific simple formula that you can learn in counselling.
Attachment styles
Understanding your attachment style and that of your partner can shine light on the challenges and dynamics you may be experiencing. Making slight adjustments in our styles can lead to much healthier, happier relationships.
Narcissistic Abuse Recovery
Narcissism can create deep fractures in relationships, leading to confusion, despair and intense emotional pain. I help with navigating through these challenges by fostering clarity, education and support. Together we will unpack what it means for your well-being and your future if you stay or go.
Growing apart
Most relationships fail for this reason. Partners stop sharing their true feelings, thoughts and dreams, conversations become transactional and before you know it you feel like roommates. As an experienced relationship counsellor, I have seen this many times. All this is fixable, the key is getting in early.
Loneliness
One of the most common issues individuals and couples bring to counselling is the feeling of being lonely within the relationship and the utter disappointment that brings. A relationship counsellor can help you explore these feelings and get to a deeper understanding of how this can be addressed individually and together as a couple.
Rebuilding Trust
Trust takes time to build and seconds to break. Betrayal takes many forms, and left unhealed can create deep resentment, conflict and bitterness. As a relationship counsellor specialising in infidelity, I have helped many couples to work on rebuilding trust and returning safety and peace.
Needs
Much of what breaks a relationship apart is founded in partners having minimal awareness of their needs, leading to an inexplicable feeling of disappointment. Needs, boundaries and people pleasing are all connected. Together we will work on uncovering your essential needs and finding ways to communicate them. Conversely, if you know your needs and they aren’t being met we can start now to fix that.
Co-dependency
This involves losing oneself in relationships, prioritizing others’ needs while neglecting personal well-being. It stems from deep-seated patterns of people-pleasing, fear of abandonment and low self-worth. In therapy we identify these patterns, strengthen boundaries and cultivate balanced relationships based on mutual respect and emotional independence.

We turned to Diana when our Marriage fell apart. At the time there seemed to be no possibility of reconciliation and counselling was almost a formality so that we could say we had tried everything. From our first session however, it was clear that Diana was not only able to help us but she genuinely wanted to. A year has passed and our marriage has survived against all odds. Beyond that though, my life has completely turned around and I can truthfully say that Diana saved me personally from a very dark place. It is easy to give into that ‘no way out’ feeling, but Diana showed me there is way, and helped me pick myself up out of a hole. We are both incredibly grateful to her for her compassion and understanding and for really making a difference in our lives and that of our children.

When I thought I could never possibly recover from the immeasurable pain of the trauma from the affair, Diana gave me the validation and empathy I needed immediately. She then guided us both, individually and together, through the stages of recovery by developing understanding and good communication skills and kept us safe. Above all she gave us both hope – and with hope, resilience and the will to work hard, committed together on a path to recovery. Just over 12 months down the track we are well on the way to developing a relationship I have only ever dreamed of; one which is based on deep abiding love, respect, and understanding.
I cannot thank Diana enough and I know my husband feels the same. He wishes he had a chance to develop the personal insights he has gained in the last 12 months, years ago. He has so much more understanding now of both his and my emotional needs and the cycle of negative self talk he had adopted. I also have a far deeper understanding of his emotional needs and together we help each other on this journey towards true giving as an expression of true love.

We had previously been to a Psychologist who was no help at all. We left there feeling discouraged and angry. After just one session with Diana we felt hopeful again and were able to start seeing each other and our marital challenges through a different lens. We learned so much about ourselves and each other during our time with Diana and now four years later we are stronger than ever.

I was in what I thought was a normal yet difficult relationship. After seeing Diana I realized I was being emotionally abused on a daily basis and that my partner had many Narcissistic traits. Diana educated me on Antagonistic Personality Styles and the devastating impacts they have. I realized the only person I could change was myself and together we worked on building my self esteem, recognizing my strengths and overcoming the guilt and shame I had experienced. Diana helped me to find myself again and for that I will be forever grateful.
