Diana E. Santacrose, Early Career Member

As an early career psychologist, ISTSS has been a professional home for me to develop a sense of a global community of professionals dedicated to trauma research and practice. I have been grateful to the rich opportunities available to emerging professionals since I was a second-year doctoral student. Annual meetings continue to be a highlight that offer a chance to build on this network and be inspired by efforts in the field of traumatic stress.

Dana Garfin, Early Career Member

ISTSS has allowed me to grow my professional network and facilitate ongoing collaborations with colleagues outside my immediate circle. The annual meetings have broadened my thinking about traumatic stress research and practice, which has served me well throughout my career.

Lia J. Smith, Student Member

I am always inspired by the presentations and colleagues that I meet at ISTSS. Every year I come away re-inspired for trauma-focused work!

Carolina Salgado, Regular Member

I have been an international member of ISTSS since 2010, because I realized as a clinician, professor and leader in my community how necessary it is to learn about trauma and its mental health consequences. And I recognize that all of us have to know ways to help our patients that are dealing with their tremendous stories.

Being part of ISTSS provides me not just knowledge regarding PTSD, but also a sense of being part of a warm, friendly and wise Global Community, which is committed to people and has an interest in developing, expanding, and making reachable for everyone the scientific progress in the field.

Sacha McBain, Early Career Member

I attended my first ISTSS Annual Meeting as a graduate student in 2014. I was so impressed with the ISTSS as an organization and the quality of the Annual Meeting I quickly adopted ISTSS as my professional home. Each year I leave ISTSS feeling energized and inspired to incorporate what I've learned into my research and clinical work. ISTSS has provided me with amazing professional development experiences, including acting as the Student Section Chair, involvement in the Membership Committee, and participation in ISTSS strategic planning. It has also helped me build a professional network that spans the globe.

In my geographic area there are very few psychologists conducting trauma research and clinical work. My ISTSS membership and involvement in ISTSS' Special Interest Groups (SIGs) has enabled me to collaborate with other professionals and establish relationships with external mentors to support my trauma work in my local community. I am so grateful for the ISTSS community and our shared mission to improve the lives of those who have experienced trauma through interdisciplinary collaboration. I hope you will join us as an ISTSS member.
