Are you using interior designers who are members of ASID?

You need Jeff Lewis.

So, I've been through several interior decorators. None have been able to really help me. I need someone to advise and counsel on finishing architectural details - i.e. help with the existing cathedral ceilings (the decorators have just said paint them) and paneling, moulding and trim work. I want to finish this before figuring out the wallpaper, window treatments, etc.

Who does one consult? An architect? An interior designer?
