Artis Stevens

President and Chief Executive Officer 

As the President & CEO of Big Brothers Big Sisters of America, Artis Stevens takes the helm of the organization at one of the most critical moments for our nation’s youth. Artis grew up the youngest in a large family with modest resources but rich in positive relationships that inspired his potential. The son and grandson of preachers, he often shares, rather than going into ministry, his calling for the past 25 years has focused on youth development and empowering young people.

As the first Black CEO in BBBSA’s 100+ year history, he is inspired by the many leaders who blazed a trail before him and sees this historic announcement as fuel for more barriers to be broken. His hard work and drive led him to become an award-winning non-profit marketing leader with a passion for building purpose-driven brands, boards, and teams. He brings unique experience having led large-scale teams, affiliate systems and transformational outcomes across nationwide youth programs, fundraising, marketing, and initiatives focusing on Diversity, Equity and Inclusion (DEI). 

Highly skilled in developing innovative marketing and fundraising strategies at the grassroots and national levels, Artis has produced compelling purpose and cause-marketing partnerships with more than 50 iconic and global brands generating hundreds of millions in revenue and media to support kids.

A proven visionary leader, his experience in marketing strategy, partnership and celebrity engagement, digital transformation and board management provides a diverse mix of expertise positioning Artis as a sought-after speaker on revitalizing nonprofit brands, infusing brand culture, and converting marketing to engagement. 

Before joining Big Brothers Big Sisters of America, Artis served as Senior Vice President and Chief Marketing Officer for National 4-H Council, leading the national marketing and communications efforts driving the organization's positioning, brand strategy, marketing campaigns, communications, digital presence, consumer insights, and affiliate marketing. His leadership doubled fundraising for 4-H and led to the recruitment of one million alumni.  He was named American Marketing Association Foundation's (AMAF) 2018 National Nonprofit Marketer of the Year, the highest honor bestowed to nonprofit marketing professionals, for his leadership in revitalizing 4-H's 100-year-old brand image. Prior to 4-H, he served as National Vice President, Marketing, Strategy & Operations at Boys & Girls Clubs of America (BGCA) where his most notable accomplishment was spearheading BGCA's new tagline and most impactful brand awareness campaign launch to date– Great Futures Start Here. 

Artis says his most remarkable achievement is being voted World’s Best Dad annually for more than a decade by his wife, Dr. Erica Stevens and his two girls.
