**In short:** Neil Clark Warren is an American clinical psychologist and author who co-founded eharmony in 2000 with Greg Forgatch. He was its chief executive in two periods, ending in July 2016, and stayed chairman after that. His compatibility-based approach shaped the questionnaire-led matching model that many dating services still reference, and DII has cited his research as the basis of eharmony's algorithm.

## Biography

Neil Clark Warren is an American clinical psychologist, author and seminary professor who co-founded the online dating service eharmony. He holds a bachelor's degree from Pepperdine University, a Master of Divinity from Princeton Theological Seminary and a PhD in clinical psychology from the University of Chicago. Before moving into business he worked as a counsellor for about 35 years and held academic posts, including at Fuller Theological Seminary in Pasadena, California. In 1995 he and Greg Forgatch set up Neil Clark Warren & Associates, a company offering seminars and teaching tools based on his 1993 book Finding the Love of Your Life. In 2000 the two launched eharmony, which matched singles using what the company called 29 dimensions of compatibility. Warren was chairman from the start. He retired as chief executive in 2007, returned to the role in 2012, and stepped down again in July 2016, when long-time executive Grant Langston took over. At that time he remained chairman of the board. He has also written around ten books on relationships. For the dating industry, Warren is associated with questionnaire-based compatibility matching and with eharmony's long-running television advertising, in which he appeared. A Dating Industry Insights article of April 2025 on algorithmic match scores noted that eharmony has long said its algorithm is based on his research. The same article said independent validation of such scoring methods remains limited. This profile gives his business roles only and does not confirm his current position at eharmony.
