Q&A: Understanding Her Approach
What got you into assertiveness training?
Early in my HR career at a multinational in Dublin, I saw burnout destroy talented people. The common thread? They couldn’t say no. They’d agree to everything, then collapse under the weight of it. I became frustrated with generic communication training that didn’t account for how we actually talk in Ireland. Being direct gets misread as rude. Saying no feels like personal rejection. So I decided to specialise in assertiveness that respects our cultural values while protecting our wellbeing.
Why is boundary setting so difficult for Irish people specifically?
There’s a cultural conditioning around being helpful, accommodating, not making waves. We’re raised to think of others first. That’s not bad—it’s actually beautiful. But it becomes a problem when you’re sacrificing your own wellbeing to avoid disappointing someone else. The guilt people feel when setting boundaries isn’t weakness. It’s a signal that you’ve internalised a belief that your needs don’t matter as much as keeping the peace. My work is about dismantling that belief, not about becoming selfish.
What’s the difference between being assertive and being aggressive?
Assertiveness is clear, direct communication that respects both yourself and the other person. Aggression is prioritising yourself at the expense of others. A lot of people avoid assertiveness because they’re terrified they’ll come across as aggressive. That fear keeps them stuck. The truth is, assertiveness is the middle ground. It’s not about winning. It’s about being heard and respected while treating others the same way. That’s why we practise specific language and tone—it makes a real difference.
How does workplace boundary setting differ from family boundaries?
Work has clearer hierarchies and consequences, which sometimes makes it easier—there’s a professional framework you can lean on. Family is harder because the relationships are deeper and more complex. You can’t just switch off from family the way you might from a colleague. Setting a boundary with a parent or sibling can stir up guilt, fear of rejection, or old patterns. That’s why family boundaries need a different approach. It’s not about being distant or cold. It’s about being honest about what you can and can’t do, and sticking to it with love.
What’s the most common mistake people make when trying to set boundaries?
Over-explaining. They set a boundary and then keep talking, keep justifying, keep apologising. That signals uncertainty. A boundary is a decision, not a negotiation. You don’t need to convince someone it’s reasonable. You state it clearly, stay calm, and repeat it if needed. Another mistake is expecting one conversation to fix everything. Boundaries aren’t magic. If you’ve been saying yes for years, it’ll take time and consistency to change that pattern. People will test your boundaries. That’s normal. Your job is to hold them steady.
What does success look like in your courses?
It’s not about becoming a different person. It’s about becoming more yourself. Success is when someone says no to something they don’t want—and doesn’t feel guilty about it. It’s when they recognise their own limits before they hit a breaking point. It’s when they have a difficult conversation with their boss or their parent, and they feel heard instead of steamrolled. And it’s when they realise that respecting their own boundaries actually improves their relationships, not damages them. That’s the transformation I see in people, and it’s why I do this work.

Her Philosophy
Why Boundaries Matter—And How They Work
Siobhan’s approach is rooted in a simple belief: your wellbeing isn’t selfish. Setting boundaries isn’t about pushing people away—it’s about protecting your mental health, your relationships, and your capacity to show up as your best self.
She combines evidence-based cognitive behavioural techniques with practical role-play scenarios drawn from real situations her clients face. There’s no generic script here. You’ll practise saying no to your boss, your parent, your friend—and discover what actually works for you.
What makes Siobhan’s work distinctive is her understanding of Irish culture. She’s not trying to turn you into an American-style direct communicator. She respects how we talk, how we relate, and the values we hold around kindness and consideration. But she won’t let those values become an excuse to sacrifice your own needs.
Her courses aren’t theoretical. They’re practical, they’re honest, and they’re designed for people who want real change. You’ll learn the language of assertiveness—the actual phrases that work. You’ll understand why you struggle to say no. And you’ll walk away with a toolkit you can use tomorrow.
What drives Siobhan most is witnessing the transformation when someone finally feels empowered to say no without apologising. And the ripple effect that creates—in their professional relationships, their family dynamics, their entire sense of self-worth. That’s why she does this work.
“Boundaries aren’t selfish. They’re how you take care of yourself so you can take care of others. And Irish culture doesn’t teach us that—but it should.”
The Core Belief
You’re not broken. You’ve just been taught that saying yes is more important than saying no. That guilt is a sign you’re being selfish. That disappointing others matters more than protecting yourself. Siobhan’s work dismantles those beliefs and replaces them with something healthier: a framework where your needs and others’ needs can coexist.
