Dr. Zimmerman received his undergraduate degree from Columbia University, and his medical

In addition to his clinical and administrative roles Dr. Zimmerman has been an active

articles and book chapters. For his research he has won numerous awards, and most recently was
the Personality Disorders section editor for the revision of DSM-5. Through the years Dr.
Zimmerman has been interviewed on NPR and quoted several publications including People
magazine and U.S. News and World Report.
Dr. Zimmerman relaxes with gardening (learning about dahlias in the past year), watching
movies, hiking, and babysitting his first grandchild.
