Could someone tell me if the punctuation in this sentence is correct?

We received a tour of the offices after which,<~~move this comma; it should be after "offices" we met in the conference room where and Jane joined the group.

Other than that one comma change (really two, I guess -- one to add and one to delete), the rest looks fine.

=)

It makes sense, but you would be better to put the comma after 'offices' instead of 'which', and to use the word 'and' instead of 'where'. eg. We received a tour of the offices, after which we met in the conference room and and Jane noined the group.
