Our Team

Whitney Brimfield

Founder & CEO

Whitney knows how to get things done. With more than 20 years of experience, she can cut through the clutter, identify opportunities, and guide you to the right fundraising strategies to fuel your mission now and in the future.

Whitney has more than 20 years of experience in fundraising, business development, and social enterprise at the local, state, and national level. During her career she has worked in public health, education, health policy, youth development, the environment, and the arts, raising millions of dollars for a variety of causes.

Along the way, she's written hundreds of grants, designed highly successful development strategies, coached Boards of Directors and executive leadership to overcome fundraising fears, engaged corporate donors, and built profitable membership programs. She brings a marketing eye to resource development, always thinking about how an organization's communications and messaging must dovetail with its investor outreach.

As Spark Point's CEO, she leads client engagements, providing strategic guidance and detail-driven implementation. She is as energized by charting strategic directions and finding solutions as she is by day-to-day program management. She is a sought after strategist and go-to team member.

Most of Susana’s work has focused on building trusting relationships with youth – be it as a teacher, tutor, or case manager. It is through these experiences that she realized that she wanted to continue to work for mission-driven organizations.
