Our Staff

Eric Ballester | eric@RHFnow.org

Executive Director

After 20 years of military service, including ten combat tours, leadership alongside America’s finest warriors, and recognitions such as the Bronze Star and special operator of the year, Eric learned that true impact comes from humility, growth, and service to others. Surrounded by elite teammates throughout his career, he focused on earning their trust, leading with integrity, and continually challenging himself to be better.

That commitment to growth continued after retirement, where he earned his MBA, built a small business, and served nonprofit communities as a volunteer treasurer and founding member. These experiences reinforced a simple pattern in his life: keep learning, keep serving, and keep showing up for those who sacrifice most.

Today, he’s honored to continue serving his country by caring for military families as Executive Director of the Rick Herrema Foundation. For the past two years, leading RHF with a vision grounded in compassion, accountability, and expansion, aiming to change the way America cares for its military families. His role is to empower the team, strengthen our mission, and help carry forward a legacy worthy of those who serve.
