Esther Giller – President and Director
As founder and President of Sidran Institute, Ms. Giller has led Sidran in the development of a broad range of programs and projects to benefit people with trauma-generated mental health problems, as well as to educate professional and paraprofessional caregivers and the public. Ms. Giller is particularly interested in and skilled at collaborative projects that bring diverse partners together to create programs to fill gaps in knowledge and expertise. She has developed innovative, collaborative projects to address trauma in settings as diverse as state psychiatric hospitals, corrections facilities, and faith communities.

She is a frequent speaker at meetings on violence prevention for medical and mental health care professionals and has often served on invited national experts’ boards convened by federal agencies.

Ms.Giller is a founding board member of the PTSD Alliance, a public education coalition that, in addition to Sidran, includes the American College of Obstetricians and Gynecologists, the Anxiety Disorders Association of America, and the International Society for Traumatic Stress Studies. This alliance was funded by an unrestricted educational grant from Pfizer, Inc.

In the mental health field, Ms. Giller is coauthor of a trauma curriculum for clergy, Risking Connection in Faith Communities (Sidran Institute Press, 2006). She is editor of two monographs: Child Protective Services: A System in Crisis (National Resource Center on Child Sexual Abuse); and Enhancing Child Sexual Abuse Services to Minority Cultures (National Resource Center on Child Sexual Abuse); and one general interest book: Multiple Personality Disorder from the Inside Out (Sidran Institute Press, 1991). She also has authored and co-authored many articles for professional and lay audiences on topics related to trauma and PTSD.

Since the September 11th terrorist attacks, Ms. Giller has been frequently sought out by national, regional, and local print and broadcast media. She has been interviewed and quoted about trauma reactions in Time and Newsweek magazines, National Public Radio-NYC, MS-NBC, CBS “HealthWatch,” and many others.

Her undergraduate degree was earned at The Johns Hopkins University and her master’s degree is from the University of Pennsylvania.

She frequently consults to the federal Center for Mental Health Services on topics related to abuse, dual diagnoses, self-injury and criminal–justice involved survivors.
