A MESSAGE FROM SIERRA

Founder & CEO, Sierra Brooklynn co.

I know what it’s like to feel out of place. To step into a new season of life and wonder where you belong.

Growing up, I was the quiet kid, and even through college. I struggled with finding my confidence within being myself. I wanted a space where I could grow as a person mentally, emotionally, and spiritually. I longed for a sisterhood that truly understood me. But when I couldn’t find one, I created it.

That’s how Sierra Brooklynn was born. A safe space where you don’t have to figure it all out alone. A community of people who will support you, grow with you, and remind you that you belong. So if you’ve been looking for a place where you’re truly seen, supported, and encouraged to grow.. welcome home!

One Reason

At Sierra Brooklynn Collective, everything we create exists for one reason:

to support who you’re becoming.

Mental health doesn’t live in one area of life — it shows up in your habits, your finances, your environment, and the people around you. That’s why our brand isn’t built around a single product, but an ecosystem of support.

Here’s how it all comes together:

BE A PART OF SOMETHING BIGGER!

Give a little, help a lot!

Mental health matters, and we believe in breaking the stigma by starting conversations. With your support, we can give away Mental Health Awareness T-shirts that help spark those important talks—whether it's a simple conversation, a shared experience, or a moment of encouragement.

Every donation to our virtual donation box goes directly toward covering the costs of these shirts, allowing us to send them to individuals who can use them as a tool for awareness, support, and solidarity.

By donating today, you're not just helping fund a shirt—you're contributing to a movement. A movement to show that it's okay not to be okay and that mental health is something we should all talk about openly.

Together, we can make a difference.
