It took me a while to meet my communication goals, because Mrs. step was not their for a while.
Does this sentence need the comma before because?
No. A comma is not needed.
But you need to capitalize Step. Also correct your homonym spelling error.
It took me a while to meet my communication goals because Mrs. Step was not there for a while.
Now is the sentence correct?
Yes, it's correct now. :-)
