Special Event for PV Library

The following story is totally made up (I was a paid tutor and summer volunteer/intern for Dorcas in the past, and had a similar experience- how I miss it!! ☹️):

Dorcas International Institute of RI and the Providence Public Library have recently collaborated this past year in an effort to empower refugee youth by providing academic tutoring services during after-school hours. The program is called 'Be the Change' where participants are paired with a tutor and together explore the benefits of reading and creative writing. Both organizations hope to expand their services and possibly accept more participants.
Dorcas and PV library has thrown public mini-fundraisers but were not successful enough to meet the goal. This time, staff and I plan to host a private house gathering with donors (and potential donors) who give regularly. The party will be located at one of the board member's very fancy abode. Together the organizations mutually decided the amount of money be raised at the event would be $3,500. We ensured to raise this particular amount by all expenses.
