Esperanza works in the greater Tijuana region of Mexico, and volunteer activities may occur in environments that involve construction sites, tools, vehicles, uneven terrain, and other inherent risks of injury or illness. Emergency treatment will be provided through available doctors, clinics and hospitals in Mexico when necessary. Please remember that caution, careful planning and prevention on your part will greatly reduce the need for emergency medical treatment. Bring your medications, EpiPen, inhalers or other needed treatments with you.
