Westminster Dallas, recently renamed Reformed Seminary is a hidden treasure in many respects. A smaller more intimate seminary located in Dallas Texas and with professors like Dr. John Hannah who double dips as the lone Reformed prof at Dallas Theological Seminary, you will be under sound tutelage and in a more affordable city than San Diego or Philadelphia.
Even the before mention DTS is a good seminary though not explicitly Reformed, you will encounter reformed brethren and of course the outstanding Dr. Hannah, many Presbyterian pastors have come out of DTS due to that man's influence.
It's Redeemer, not Reformed, in Dallas.
And Dr. Hannah teaches some classes there. So there is no need to a Dispensational seminary to benefit from his teaching.
As for DTS, folks have been saying 'Its changing' for at least 15 years, but it still has a long, way to go. There are much better choices if one wants Reformed; it is at the top of the class if one wants Dispensationalism.
