Organizations

Hi, I'm Marie Cleary — and welcome to ThirdSpace.

I created ThirdSpace in 2014, inspired by a deep belief in the power and potential of people to achieve great things when they have the right support and training. Our work focuses on helping individuals and organizations strengthen their approach to management, leadership and people development, all grounded in Psychology, Neuroscience and ethical practice.

Over the years, ThirdSpace has grown organically, helping businesses build the skills that really matter: leading with clarity, managing with confidence, and creating spaces where people feel valued and supported.

Whether you're navigating change, developing your leaders or looking to build a healthier workplace culture, we're here to support.

Thanks for stopping by. We'd love to learn more about what matters to you.

"We believe that when you invest in your people, extraordinary results follow."
