About Me

I was never meant to keep quiet

 I was often the quiet one…
the girl who noticed everything.

Early on, I learned that being “good” meant staying small.
That to keep the peace, to stay safe, you had to keep your mouth shut.

But I noticed things.

I noticed unfairness. Injustice. The way women were expected to carry everything, still smile politely and make the dinner.

And eventually, I couldn’t not speak.

My voice didn’t come out polished — it came out raw. Raging. Shaking. But it was real. It was messy. And it was mine.

I’ve spent my life since then helping other women find theirs.

Now I run This Sister Speaks, my group mentoring programme that gives women the space, strategy, and support to stop second-guessing and start raising their voices.

I also speak inside organisations, helping teams build confidence, courage and culture, because when women and gender non-conforming people speak, workplaces change.

Things I Believe…

Your story holds power

(yes, even the parts you’ve been told to hide!)

Leadership isn’t about being the loudest.

It’s about being the bravest, most courageous we can be.

Confidence isn’t a personality trait.

It’s a skill. Like a muscle we can build and grow.

In telling the truth

even when it makes people uncomfortable. Especially then!

Women raising their voices changes everything —

families, workplaces, policies, futures.

My work is rooted in

activism, social justice, courage, and care.

I’ve spent the last 15+ years inside movements, campaigns, and boardrooms, helping people make themselves heard and teaching organisations how to truly listen.


I’m trained in leadership, advocacy, and facilitation. But my deepest qualifications come from lived experience, of growing up silenced, and choosing not to stay that way.

I’ve been inside trade unions, activist spaces, nonprofits and public sector, as well as corporate boardrooms. 


I stood for Parliament in 2019 against the (then) Attorney General. 


I’ve spoken on t’internet, TV, and radio talking about education, poverty, housing, climate justice and more. 


And I’ve helped hundreds of women find the words (and the nerve!) to speak up.

  • What People Say

    "Siobhan's taught me how to be bolder with my activism, clarify my intentions and direction. The world of activism is messy, but thanks to this course, I've been given a complete toolkit on how to structure the way forward. The course even instilled in me the confidence to pitch a book to a publisher! I learned so much in the community calls, and came away each week feeling topped up, restored and ready to take action. I couldn't recommend enrolling in This Sister Speaks more."

Inclusion Statement

To me, inclusion isn't about being nice or virtue signalling, it's about shifting power.

I'm on a mission to actively challenge and burn down the systems that make inclusion necessary in the first place. I want to create a world where collective liberation for all is THE priority; where all stories matter and where all voices are heard.

  • I strive to ensure all voices are heard and everyone is given opportunities to participate and contribute.

    I offer access to slide decks and edited transcripts of my workshops, and am currently working with specialist Black women web designers and branding specialists to make sure my new website and brand are accessible and inclusive.

  • Over the last decade, I’ve led campaigns on education, housing, period poverty, holiday hunger, and more, because systemic change doesn’t happen by waiting politely.

    I’ve spent years fighting for working-class voices in politics and business, breaking down the elitism that keeps people shut out. In my work this looks like offering various levels of support - including free workshops and payment plans, as well as offering scholarships - to ensure financial accessibility.

    My clients can work with me on Zoom, via Google Docs and email, and sometimes WhatsApp or Voxer, because we all learn in different ways, and what works for someone might be overwhelming for someone else.

  • Women, trans and non-binary folk, disabled people, racialised communities, and the LGBTQ+ community. I won’t go on a podcast or sit on a panel if I’m just another voice, I’ll suggest someone whose story is missing instead. But I am well aware that I don’t know everything. I'm always learning and growing, reading and studying from or with authors and experts who aren't cis-het old white dudes or Karens. 

    And I believe it’s important to mention that I’m raising three boys as feminists and allies, because real change starts at home.

  • Moving forward, I am committed to creating alternative text descriptions for all images on social media within Q3 of 2025 and to fully embed that good practice.

    I will do an accessibility and inclusion audit on my website, and add to my Google calendar regular review opportunities.

    I will continue to regularly review and update all my business practices through an anti-oppressive lens and commit to publicly sharing my progress and learnings related to inclusion at the end of each quarter on Instagram, LinkedIn and my blog.

Your voice has power.
Let’s use it.
Join the growing movement of changemakers who are done being polite and ready to make a difference.
