Admission to the West Conn Master of Health Administration program has been reopened.  Western Connecticut State University says with the health field in continuous change, the program designed to create leaders who will find opportunity in that upheaval.  The Master of Health Administration program has been offered at West Conn for more than three decades, but admission was suspended two years ago to re-examine the courses to make sure they still apply to today's health care system.   The program is run through the Ancell School of Business and offers a course on negotiation.  Students also earn credits for residencies.
