I never imagined I'd be a
Couples Therapist or Sexologist

I'm a country girl who was shy and embarrassed about sex. Sex was never something spoken about at home or at school growing up.

My journey to more satisfying sex and intimacy began when I attended a Tantra workshop (a kind of yoga which benefits body confidence, relationships and sex) over 15 years ago. Tantra helped me become more confident, attract a loving relationship and gave me tools for knock-your-socks-off sex. One thing led to another and I was soon teaching.

Helping people feel confident and comfortable with sex and have a loving relationship became my passion. I wanted to help people as effectively as possible, so I studied for almost a decade at three prestigious universities to discover how.

Over the past 15 years, I've built my reputation on sharing practical tools and getting results for my clients. I feel privileged to make a difference in people's relationships and lives.

I've supported thousands of individuals and couples to improve their relationships and sex lives through therapy, regularly appear in popular media and write a popular weekly advice column on sex and relationships.

I'm a former Couples Therapy lecturer and have now created my own Academy, training other therapists to competently deal with the issues of relationships and sex.

The Relationship Harmony Method

A four-step framework built on decades of research.

Most couples come in thinking they have one problem, what the research reveals is that it's rarely just one thing. That's why every client starts with the full picture, before anything else.

I built this method because the couples and sex therapy worlds are usually kept separate, you see one specialist for communication and connection, and an entirely different one (if you can find them) for intimacy and desire. In my experience, that split doesn't reflect how relationships actually work. The two are deeply connected, and treating them separately is often why progress stalls.

The Relationship Harmony Method integrates the two: it draws on The Gottman Method (one of the most researched approaches to couples therapy in the world), Emotionally Focused Therapy (a leading evidence-based model for repairing attachment and connection), and clinical sexology, brought together into a single, coherent framework rather than three separate approaches loosely bolted together.

Every therapist on my team is trained in this exact method, so the care you receive doesn't depend on which of us you see.

Vision & Assessment

A comprehensive, research-based assessment gives us a tailored map of exactly where your relationship is, and where it can go.

02

Connection

Rebuilding emotional closeness, trust, and the sense of genuine partnership that relationships need to thrive.

03

Communication

We build the foundations for real conversation, breaking cycles that keep you stuck and creating new patterns that actually last.

04

Intimacy

Integrating physical and emotional intimacy, because this is the area where most relationship therapy stops short. We don't.
