"I'm thankful for finding community among compassionate role models helping innocent animals who are suffering and neglected."

We offer a wide range of ways to get involved, each with varying requirements, responsibilities and commitment levels, and we provide all of our volunteers with guidance and training as needed. To ensure the safety of the organization’s people and property, and the animals in our care, we conduct a background check of our volunteers’ criminal history.* Additional background check components will be included based on the scope of the volunteer work. The organization will consider volunteer applicants with a criminal record on a case by case basis. Typically, crimes against people or animals, or crimes of a more recent nature, may be cause for us to decline a volunteer application.

*Some volunteer roles do not require a background check.

The Humane Society of the United States is pleased to announce that it has been certified by Points of Light, the world’s largest organization dedicated to volunteer service, as a Service Enterprise! Achieving Service Enterprise certification is a prestigious accomplishment for an organization. In fact, organizations that certify join the top 11% of nonprofits nationwide in volunteer management and organizational performance. Certification signifies that organizations have the capability and management expertise to strategically use volunteers to improve the performance of their organization.
