Objective: When I delete a row on one sheet, I want to delete that same row
on two Other sheets.

I don't believe the "Worksheet_Change" handler will work unless there was
some way to test if a row was deleted...

I was wondering if there was a way to create custom event handlers (i.e.
BeforeRowDelete).

Psuedo code would look something like:
Private Sub Worksheet_BeforeRowDelete(Blah Blah Blah...)
myRow = ActiveCell.Row
Sheets("Some Sheet").Rows(myRow).Delete
Sheets("Some other Sheet").Rows(myRow).Delete
End sub
