Not to speak for Wes, but R.C. Sproul Sr. has a doctorate of some kind from Whitefield. IVP has shown this about him on their books in the past:

"Sproul, a noted speaker, author and minister, is president of Ligonier Ministries, which he founded in the early 1970s. His Renewing Your Mind broadcast, sponsored by Ligonier Ministries, is now heard on more than 300 radio stations in the United States and in more than 100 countries throughout the world. Sproul is senior minister of preaching at St. Andrews Chapel and professor of systematic theology and apologetics at Reformed Theological Seminary. He holds doctorate degrees from Free University of Amsterdam and Whitefield Theological Seminary."

But I don't know specifically what that doctorate from Whitefield is in.
