Fundraising Simplified. Impact Multiplied.

Strategic fundraising support for nonprofits ready to grow.

Duke Consulting

We love what we do. There is nothing more exciting than seeing an organization ready to grow. Too often, nonprofits are rich in vision but stretched on capacity. We step in, build the foundation, equip your team, and stay until the results are real. Duke Consulting is for small teams with big vision.

Best practices.

Real results.

There is nothing more exciting than seeing a ministry or school ready to grow. Too often, organizations are rich in vision but limited in capacity. When thorough training and seasoned leadership are out of reach, we provide trusted fractional development leadership that fills the gap and gets results.

who we are Duke Consulting LLC

Built to Activate.
Driven to Produce.

Unlike other consulting firms, we get excited about strategy and real outcomes. We are built for effective change, not presentations that sit on a shelf.

We Bring Best Practices

Proven development approaches so your team does not have to figure it out from scratch.

We Equip You With The Tools

Systems, frameworks, and skills your team needs to keep producing results long after we leave.

You Close The Deal

Nobody tells your story better than you. We prepare your leadership and celebrate every gift that comes in.

how we work Two Ways to Engage

We Meet You
Where You Are.

Some organizations need targeted support in one specific area. Others are ready to build the full development infrastructure. We built both tracks so you can start exactly where it makes sense.

Targeted Support

Specific help, when you need it.

Grant writing, major gift strategy, year-end appeals, fractional leadership. Hourly and retainer engagements for organizations that have a clear gap to fill.

The Signature Approach

From vision to funded reality.

A four-phase, 12-month engagement that brings your nonprofit fully donor-ready. Tools, strategy, story, and the infrastructure to sustain it all.

01 — Assess

We listen before we lead.

A full development audit, messaging review, donor data analysis, and revenue trends. We surface what is real before we recommend anything.

02 — Clarify & Build

Story first. Tools second.

Your case for support, storytelling framework, grant templates, and annual giving roadmap. You leave this phase equipped and aligned.

03 — Activate

We work it with you.

Donor cultivation, solicitation training, grant submissions, board coaching. We are in it alongside your team, not above it.

04 — Sustain

Built to last.

Performance metrics, retention strategy, leadership alignment, and the confidence to carry the work forward.

"The gap between where you are and where you want to be is smaller than you think."

Adeline is a diagnostician at heart, someone who loves spotting untapped potential and implementing best practices for a strong foundation and nourished pipeline. The result: a culture of giving that continues to grow.

With over a decade of experience in nonprofit fundraising, Adeline has built and grown development programs across some of San Diego's most respected institutions, spanning performing arts, higher education, marine science, private K–12 education, and Christian ministries.

Her work encompasses the full fundraising spectrum: individual, major, and estate giving, corporate partnerships, grant strategy, donor stewardship, capital campaigns, and building programs entirely from scratch. She understands what it takes to earn trust, cultivate relationships, and inspire lasting generosity.

Adeline founded Duke Consulting to bring that same institutional expertise to smaller nonprofits, for organizations with big missions but limited bandwidth. Her approach is practical, incredibly donor-centric, and built to inspire a culture of giving.
