Virginia Dunn

Youth Volunteer Coordinator

Virginia has been a volunteer for Heart Ranch since 2018, and we consider her a precious unpaid staff member. When she came along, we were underutilizing youth volunteers, so she started our youth volunteer group, Impact! She organizes all youth volunteers, leads their biweekly meetings, leads mentorship sessions, and manages our social media pages. Even though she didn't know much about horses when she came, her 20 years of experience working with teenagers at various churches made her a valuable member of the team. She strives to provide a safe, encouraging environment where teens learn responsibility, self-confidence, and teamwork. Her husband does a great deal for the ranch, and her daughter, Mercy, is a youth volunteer.


Marleena Sheffield

Program Assistant

Marleena is our first paid staff member ever. She started out as a volunteer and graciously accepted the job of helping us write grants to fund the ranch, and keep the horses in shape. We are so excited to have her on our team, and we know the horses are too!
