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.

Calvin holds a Bachelor of Arts in English and a minor in Spanish from the University of South Carolina Honors College, as well as Master of Arts in Communication Research from the University of California, Davis.
