Orsillo, PhD, is Professor of Psychology at Suffolk University in Boston, Massachusetts.

Dr. Orsillo has published over 70 journal articles and book chapters, coedited two books, and coauthored two books. Together, Drs. Roemer and Orsillo have developed an acceptance-based behavioral therapy for generalized anxiety disorder.

Their self-help book The Mindful Way through Anxiety draws from their decade of research in this area to provide guidance to people struggling with anxiety.
