He held M.A. and Ph.D. degrees in clinical psychology from Columbia University and American Board of Professional Psychology (ABPP). He also founded and was the President of the New York City-based Albert Ellis Institute for decades.

Based on a 1982 professional survey of US and Canadian psychologists, he was considered as the second most influential psychotherapist in history (Carl Rogers ranked first in the survey; Sigmund Freud was ranked third).^[3][4] Psychology Today noted, "No individual—not even Freud himself—has had a greater impact on modern psychotherapy."^[5]
