He completed his doctoral training at The University of Detroit Mercy, a private Jesuit University, and interned at Henry Ford Hospital in Detroit. He has practiced in Michigan and now in New York City with a special emphasis on relationships, most particularly on improving understanding, communication, compassion, and cooperation between intimate partners. He also works with individuals searching for ways to cope with and adapt to the often dispiriting demands and challenges brought on by life changes, big and small, or just by everyday life. In his spare time, Dr. Haddad has been known to lay down a tight bass line to classic rock tunes that some have characterized (mistakenly) as just a bit too loud.
