The Rocky Mountain Chapter American Theatre Organ Society (RMCATOS) is dedicated to the preservation and promotion of theatre organs and theatre organ music.

The organization has monthly socials that are centered around theatre organ music in general, but also include piano and other instruments.  Several times a year the organization produces public theatre organ events.

The Membership Fee is $15 per calendar year, per household.
Membership is open to anyone who has a love of music and/or $15!

Please join us at one of our socials or public theatre organ events!
