The Ark's staff is a group of 32 dedicated individuals: those who work directly with the children, as well as additional ones handling other duties necessary to the shelter's operation.

The child-care staff has had extensive training in child care and is certified to give cardiopulmonary resuscitation (CPR) and first aid. It takes a unique individual to care for The Ark's residents, and each must have the proper knowledge to handle any situation. Child-care providers are divided into groups, each of which has a team leader. The employees work rotating shifts to help take care of the children. They are like second parents, just as the shelter is a second home to the residents. A sufficient number of employees are required to staff the shelter during its hours of operation: 24 hours a day, seven days a week.

All employees and prospective volunteers undergo background checks.

The volunteers are highly valued because of the roles they play, whether working directly with the children or in other capacities.
