My daughter attended this school, following in her mother's footsteps, but unfortunately there were no transcripts issued. Where can she get it for a job interview?

Did she try asking the school yet? Odd she would attend, graduate and never ask about transcripts or anything.

It seems to have closed in January 1996. I gather Sawyer Business School was a for-profit chain, much like Kaplan or ITT - dozens of them went out of business in the 90's.

you can navigate to the contact info for the state licensing agency in MI, who should have records for closed colleges.
