Welcome to GJ, Pat.
I Googled them and found several local door installers, mostly in Utah. They do list Clopay as a door product they sell, so not sure if you are looking for a door brand or local installer.
To get a better answer to your question, post it in the 'General Garage Discussion'. This thread is really for introductions and there is not as much foot traffic through these parts.
Good Luck and Welcome
