Sort Orders (advanced)

I have a list of students, entered using a dialog form,
that inserts each student row above a named range row.
I want the rows (C8:C38)- the maximum
no of students is 30,to be automatically re-sorted by
teacher name on entry (e.g. Mr Dickens) students first
and then mr Evans students, etc. The tricky bit is that
i want each of these lists to also be in alphabetic
order so that for example all students in Mr Dickens
class start at A and go down. Is this possible to
get to automatically occur. Thanks in advance
