Your mental health is our priority

we're a mental health charity that provides fast and effective therapy for people who are struggling.

how can you join us in saving and changing lives?

it all began with gary.

here is the story of why bigmoose began. our why is our purpose —the driving force behind everything we do.

every great business, charity and mission needs a ‘why’ and ours is keeping the legacy of our friend gary ‘moose’ cloonan alive.

we hope we make him proud with our mission to leave the world better than we found it.

in january 2022, we started our mission to raise £1,000,000 for mental health. we are so proud that within 486 days we achieved this incredible goal and completed project 1 million! over 11,000 people donated and have helped us to save and change lives.

but we know there is more work to be done.

we have a big dream to make a difference in the world. we are on a mission to raise 15 million pounds for mental health, this is going to be a mammoth task, and we are going to need all the help we can get, but our passion to change lives is what drives us, and makes us believe we can do this.
