I just looked at the SCA website and they have a directory of names but it’s in company names not individuals.
You could do the following:
1. Go to the Contact Us button on the SCA website and email your concern; or
2. Call the SCA and say you understand she worked as a strata manager but you don’t know where. The SCA may or may not have her details depending on whether she’s a member of the SCA; and
3. I would not volunteer your strata plan details or that you’re unhappy with your current manager, who if he’s a member of the SCA, why would the SCA help you dismiss him?
As to your unhappiness with your strata manager. Do not assume the next manager will be any better.
Good luck!
