Final answer:
The correct answer is E. All of the above.
Step-by-step explanation:
Giving families a single point of contact within your office has several advantages. Firstly, it allows families to know whom to call to get their questions answered. Secondly, the point of contact can get to know the families and establish rapport with them, which leads to better support and service. Lastly, having a single point of contact allows everyone else in the office to continue their work without getting sidetracked, as the point of contact should have access to and know where to get all the information available.
