About of Rhiannon Derrig

Rhiannon Derrig is a counsellor and psychotherapist based in Sydney, supporting people across a range of mental health and relationship concerns. Sessions are available at Suite 816 & 919, 185 Elizabeth Street, Sydney NSW 2000, which makes it a convenient option for many locals.


In day-to-day practice, Rhiannon works with adults, couples, and families. Many people come in when things feel stuck or heavy. At times, that can be stress that builds up at home or work, changes in mood, or worries that won’t quite switch off. Some clients also seek help around communication problems, trust issues, parenting stress, or the strain that can follow major life events.


Rhiannon also carries out mental health assessments. These check-ins help sort out what is going on, what support might help most, and what practical steps can make day-to-day life a bit more manageable. From there, the focus often shifts to coping skills development—learning ways to handle tough moments without getting pulled under by them.


Therapy with Rhiannon usually feels grounded and tailored. Individual therapy sessions focus on personal goals and what’s been going on for the person, while couples therapy sessions look at patterns that keep showing up in the relationship. Family therapy sessions can bring more than one voice into the room, especially when the whole household is affected and everyone is trying to move forward.


Over time, clients often find that sessions don’t just talk about what happened. There’s also room for what to do next. That might mean building better boundaries, learning how to calm the body when things feel too intense, or working out more helpful ways to talk when emotions run high. The aim is steady change, not quick fixes.


Rhiannon’s approach is shaped by training in counselling and psychotherapy, plus hands-on experience in therapeutic work with individuals, couples, and families. The combination helps keep sessions practical and respectful, with care taken to support people at their own pace.


Language can matter, and therapy should feel safe. Rhiannon’s work is designed to be clear, calm, and easy to follow, even when life is messy. For many people in Sydney, that simple, steady support can make a real difference—one conversation at a time.
