There are usually residents who are interested in getting to know faculty members, especially faculty who teach in their major. Let them take some responsibility for maintaining contact with your Faculty Fellow, but not all. You are still the RA for the floor. Faculty will appreciate getting to know colleagues who are Faculty Fellows and you can boost program attendance through co-programming. Including the family will remove a possible obstacle to your Faculty Fellow's participation in a program and will give your residents a chance to get to know faculty and staff as real people.
People are more supportive of things when they have been included in the planning.
Use a social event with your Faculty Fellow as a way to initiate planning for other Faculty Fellow activities. Many faculty and staff have innovative ideas for things to do with the residents. Many of them have been with the program for a number of years and have lots of thoughts on what may or may not work.
