Webster University has partnered with Grenoble Ecole de Management to offer a part-time DBA program. This is the link to the program. There are 4 4-day residency periods in Switzerland. The degree is awarded by Grenoble.
Edit: Residencies are in Geneva as well as Grenoble. Apparently, the partnership is not that new as applications were due July 27th with an October start. Also, it is about $55,000.
