Organists Online is an internet based system for putting churches and choirs in contact with organists and pianists, founded in November 2000. It's free to access and free to use at all stages.
The site includes a page of about 1,000 Listed Organists with contact and basic professional details. There is also a list of Registered Organists, each with an individual page full of information.
If you want to find any particular organist, or want to know more about organists who reply to requests, these pages will help you.
If you don’t mind who comes to play in your church, fill in an online form, and then only organists who are available when/where you want will respond. You can use the Listed or Registered pages to help make a choice.
