Isiah McKimmie & Relationship Harmony
Couples Therapy,
Relationship Counselling
& Sexology
Most couples therapists never ask about intimacy. Most sex therapists never address communication. We do both, so your relationship can thrive.
A relationship you love
is closer than you think
Whatever’s brought you here, it’s possible to feel close again — to laugh together, enjoy each other, and stop worrying about your relationship.
You're at a crossroads
You don’t want your relationship to end, but you know you can’t keep going the way you are. You may feel stuck in the same patterns, worn down by unresolved tension, or quietly drifting further apart. Perhaps intimacy has faded, trust has been shaken, or the emotional distance feels heavier than you want to admit.
Get started →Something's missing, and you can't quite name it
You’re successful in most areas of your life and you have a great relationship. But there’s one part you can’t quite work out — and it’s frustrating, because you’re used to being able to sort things out.
Get started →You're experiencing challenges with sexuality, and you're not sure where to go
If sex has become something you worry about rather than enjoy, if you’re experiencing challenges with function, or desire has changed — we can help.
Get started →You've been referred, and you're not quite sure what to expect
Maybe your GP, psychologist, or another practitioner suggested you get in touch. You might be navigating changes in desire, pain, performance concerns, or a physical or medical issue that’s affecting your sex life. We provide safe, non-judgmental support.
Get started →Hi, I'm Isiah
I know how it feels to want more from your relationship, more closeness, more ease, more of that feeling that you're genuinely a team. After almost two decades working with couples, I've seen what's possible when people get the right support. And I've built my practice around making that possible for you.
We offer premium relationship counselling, couples therapy, and sexology for individuals and couples who want to strengthen connection, improve communication, and create deeply satisfying relationships.
I'm a Couples Therapist, Psychotherapist and Sexologist, with Masters degrees in Relational Psychotherapy and Psychosexual Therapy, and advanced training in the Gottman Method and Emotionally Focused Therapy. You may have also seen me on Channel 7.
Today, I'm proud to lead a growing team of Relationship Counsellors, Couples Therapists and Sexologists, all passionate about supporting people like you. I personally train every therapist here, so whoever you work with, you're in expert hands.

All programs at Relationship Harmony are guided by the Relationship Harmony Method — a structured, research-informed approach developed through years of clinical practice with individuals and couples.
This method brings together decades of research into strong, satisfying relationships, the latest findings from neuroscience, and the scientific study of sex and intimacy. It creates meaningful change across the areas that matter most.

they work with us.
There are so many ways we've changed since we started seeing you Isiah, but they've all added up to us having a closer, more intimate, loving and sexual relationship with each other.
Thank you for making this process, which could have been much more uncomfortable, as easy as possible. We feel connected now and it's more fun. Initiating intimacy feels easier and pleasure comes easier.
Everyone should do this. We are really open about our sessions with Isiah, the reaction of friends is often 'oh no! That's not good'. But it shouldn't be like that, things shouldn't be falling apart before you work on them. We are firm believers that you should take preventive actions.
Growing up, I felt ashamed about my curiosity and fascination with sexuality. Isiah has empowered me to take charge of my sexuality and embrace being a sensual woman. My time with Isiah has been life changing.
