Along with the efforts made by the staff, reduced recidivism is seen when inmates are able to stay in contact and supported by their family or friends who are not incarcerated so mail, phones, and visits are provided. 

Visits are in person, and are via video and an account is created online to book and complete visits, allowing both visitors and inmates to schedule a visit.
