India McDonald
Nursery Coordinator

My name is India McDonald I have been nursery coordinator at Allisonville Christian Church since 2012. I love my job, getting to in the nursery every Sunday. I get to be a mom all over again to sweet little babies from lots of different families. I enjoy decorating our nursery for the holidays - it's always something new and exciting for little eyes! I do as much as possible to upgrade the nursery and keep children and parents alike as comfortable and happy as possible.  I also draw a lot of our decorations and coloring pages. I have two children of my own who are 7 and 8 and also love Allisonville. It's hard watching the little ones move on from the nursery to worship and wonder but I still get my share of sweet visitors who miss me, that means the world to me and keeps me coming back to work every Sunday. Thank you for letting me be apart of your church experience!
