Co-Founder, Social Impact Solutions | Accelerating Fundraising + Social Impact for Nonprofits & Mission-Driven Companies

Driven by a mission to help the impact sector thrive, we started Social Impact Solutions to empower nonprofits and mission-driven companies to measure and market their social impact.
We offer strategic guidance through tailored sessions focused on social impact measurement, funder acquisition, and growth strategy. 

Our goal? To equip organizations with the tools they need to not only make a measurable difference but to communicate their impact effectively.

Outputs tell us what happened.
Outcomes explain what changed and why it mattered.

Effective nonprofit impact communication focuses on both, but prioritizes change.

I hope this helps!

Why Outputs Alone Don’t Explain Impact

Volunteers don’t stay engaged because of tasks, they stay engaged when they feel valued.

Small incentives and intentional appreciation can dramatically increase volunteer engagement.

We shared these insights in our recent webinar to help nonprofits strengthen their volunteer culture and retention.

I hope this helps!

Clear impact reporting builds informed, confident supporters, not passive donors. If you want long-standing partners, show your donors the impact they create when they give.

I hope this helps!

What Donors Learn From Clear Impact Reporting

Data doesn’t replace storytelling, it reinforces it.

Together, they create impact communication donors can believe in.

How Data Strengthens Credible Storytelling

Data literacy empowers teams to use information, not just collect it.

Stronger understanding leads to stronger impact communication.
