Our services

Development Planning & Implementation

Sustainable fundraising doesn’t happen by accident.It’s built on a clear strategy, realistic goals, and a plan your team can actually execute. We work alongside nonprofit leaders to assess where you are, map where you want to go, and build the roadmap to get there. Then we stay in your corner as you put it into practice.

Grant Writing

You know your mission inside and out. Translating it into compelling grant language — while running programs, managing staff, and serving your community — is a full-time job on its own. We take the weight of the grant process off your plate, from building a funding strategy to writing proposals that make funders take notice.

Donor Engagement & Communications

Donors and corporate partners want to invest in organizations that inspire confidence and tell a compelling story. We help you build those relationships and develop the materials that turn first-time supporters into long-term champions of your work.


I have collaborated with Andrew Cattell for two years after our nonprofit hired him to enhance our fundraising and grant writing capabilities. Andrew has proven invaluable in securing multiple grants for our organization through his strategic approach and exceptional writing abilities.

His grant proposals are meticulously crafted and effectively communicate our mission to funders. Beyond his technical expertise, Andrew brings a collaborative spirit that makes him a joy to work with. His professionalism and results-oriented approach have significantly strengthened our fundraising capacity.

I recommend Andrew without hesitation to any organization seeking to improve their grant writing and fundraising outcomes.

AI and Large Language Models are powerful tools and resources that can definitely be a valuable part of organizational development and communication strategies. However, we find that building authentic connection with foundations, donors, and corporate partners takes a human approach. Your story is unique and there is specific language, imagery, and impact data that is appealing to specific audiences.
