I am a clinical psychologist who works across a variety of presentations including anxiety and mood disorders. I hope to bring a warm, empathic and authentic approach to the issues that people bring to therapy. I recognise the investment that people make when they share their difficulties with someone and commit to therapy, and work to honour that commitment by delivering evidence based treatments, that are tailored to a persons needs. I’ve benefitted greatly from the experience of working across a range of inpatient and outpatient hospital settings.

I support couples to have the relationships they desire. The fact is that when your relationship is rubbish, everything feels rubbish. Often in relationships, the same patterns play out again and again, but it can be impossible to see them (let alone change them), when you are living them. My role is to recognise the pattern, understand why it is happening, and how it is impacting your relationship.

Are you struggling with your relationship? Having issues with: communication as you don’t feel like you’re on the same page, conflict resolution - as nothing seems to get resolved, feel like you’ve lost the intimacy and closeness, and you no longer trust one another, are you struggling with sex, finances, house responsibilities, parenting or in-laws? You've tried everything you can think of, but nothing seems to change. The love is still there and you want the relationship to work, you're just not sure how to go about it.

Infidelity Therapists
How does therapy for infidelity work?
A skilled infidelity therapist will provide a safe space for clients to communicate their feelings and concerns. The goal is to be completely honest about what led to the cheating and how it has affected the entire family to prevent it from recurring in the future. The therapist will help the clients work on rebuilding mutual trust and respect and developing better communication and conflict-resolution skills. If the goal is to remain a couple, clients will learn the “danger signs” for their specific relationship, and they will make a renewed commitment to be faithful.

How long does therapy for infidelity take?
Recovery from infidelity can take time, and it can vary from person to person. Generally, a therapist will want to see the clients at least once a week for around six months. Then the sessions can be arranged as needed, depending on the clients’ individual needs. While therapy may end or shift to an as-needed basis, it can take up to two years or more for some clients to fully recover from infidelity.

How does therapy help the partner who was cheated on?
When a client discovers their partner’s infidelity, their trust in the relationship and in the life they had together may be shattered. They often experience mental health symptoms, such as anxiety, depression, grief, and post-traumatic stress disorder (PTSD). They don’t always want to stay in the relationship; they may feel ambivalent or may even want to leave. Therapy gives these clients a safe and healthy way to communicate all of their complicated emotions and concerns.

How does therapy help the partner who committed infidelity?
Infidelity often occurs when one or both partners’ emotional needs are not being met in the relationship. Therapy can help this client understand why they cheated and figure out how to address those unmet needs without resorting to infidelity in the future. This can lessen (but not entirely eliminate) the risk of repeated infidelity. Clients who cheat may also feel intense guilt about deceiving their partners, a sentiment that they can work through in therapy.
