Th.M. is a unique degree nowadays. It's supposed to be a "researched graduate theological degree", but then institutions like Dallas Seminary kind of blow that theory away (Dallas, instead of issuing M.Div., gives Th.M.) Even different institutions have different levels of requirements for Th.M. At Westminster Seminary in Philly their Th.M. is pratically "half a Ph.D." which prompted many students to go ahead and get a Ph.D.

Anyway, if you're in Pittsburg, and geography is an issue, then I guess Westminster Seminary in Philly would be your best bet... but stick with the ST department degrees as their BT department are having some... ahem... house cleaning...
