This article reports on a conversation between 12 lesbian, gay, bisexual and transgender (LGBT) psychologists at the first international LGBT Psychology Summer Institute at the University of Michigan in August 2009. Participants discuss how their work in LGBT psychology is affected by national policy, funding and academic contexts and the transnational influence of the US-based stigma model of LGBT psychology. The challenges and possibilities posed by internationalism are discussed with reference to the dominance of the United States, the cultural limits of terms such as 'lesbian, gay, bisexual and transgender', intergenerational communication between researchers and the role of events such as the Summer Institute in creating an international community of LGBT psychologists. © 2010 Taylor & Francis.
