Whitney Brimfield Principal and Founder

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 founder and principal, 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.

She holds a Master of Health Science from Johns Hopkins Bloomberg School of Public Health and a Bachelors from Haverford College. In her free time she enjoys creative pursuits like photography, painting, and improv and spending time with friends and family.


Calvin Koon-Stack, Outreach and Engagement Specialist

Calvin is a storyteller with seven years of experience in media and nonprofit communications. During his career, he has worked in print and radio, and in 2015, he moved to DC to work in strategic communications, conducting projects for organizations like the Rockefeller Foundation, Amnesty International, and HumanitiesDC. 

As Outreach and Engagement Specialist at Spark Point, Calvin manages the firm’s digital presence, including its blog, website, and social media. He enjoys nothing more than learning from people who have made change on the ground—Spark Point's clients—and he looks forward to lifting up their voices, sharing their stories, and building an engaged community.

Calvin holds a Bachelor of Arts in English and a minor Spanish from the University of South Carolina Honors College. A little too predictably, he loves reading in the parks and coffeeshops of Eastern Market. He also enjoys cycling around town, hiking in Shenandoah National Park, and taking pictures of his dogs.
