Remember she nearly got expelled from HS protecting her friend the principal's daughter who was the real culprit due to low grades. Keith was her lawyer in student court. That was the first time viewers learned he had law school ambitions. BTW, do high schools really have student courts, then or now? Mine didn't. .Maybe it was only in CA.

Getting to the point, I saw the actress's name who played the principal's daughter, Tannis Montgomery I believe. I think she played the scheming cheerleader who flirted with Greg on the Brady Bunch.
.

I looked up her name, it was her. The character's name was Cindy. Here is list of her other work. I am assuming she left the acting world . IMBD on!y list her credits to the early 80's.
