About Me

I was always interested in science and problem solving, but I felt that the human aspect of hard science was often missing. I wanted to work in a field where I could help give a voice to people who didn’t have one.

After working for some time in an LGBT clinic in Chicago, I was inspired to become a physician. However, I found myself wanting to know more about people than I could discover from a quick clinical appointment. I loved having the opportunity to hear people’s stories, and I quickly realized that this is something psychiatry—especially child psychiatry—would let me focus on.

I am currently the director of the Gender and Sexuality Service at NYU Langone’s Child Study Center, a service I began several years ago with the goal of improving treatment outcomes for transgender and gender nonconforming children, adolescents, and adults. Through the clinical service, I provide personalized gender assessments and individual and family therapy, as well as school consultations and professional development. It’s quite a unique program, and I am fortunate to be one of the few child psychiatrists in this city that has the opportunity to do this work.

I also run a consulting service at NYU Langone for children with medical conditions who are in need of psychiatric help. In this service and in my practice, I work closely with patients and their families, as well as a team of psychiatrists and psychologists who work together to ensure that best practices are followed and patients receive compassionate care.

In my practice, the child always comes first. This is especially important during gender therapy. I follow a very affirmative model of care. My job and goal are to allow children to be themselves, to find their own strengths, and to use their own voice.

I am currently participating in several research projects. As a member of a research collaborative—the Adolescent Gender Identity Research Group—I work with other investigators in Amsterdam, London, Toronto, and other places to collect information on transgender youth in an effort to better understand their needs. I am also studying the impact of care for children with co-occurring gender dysphoria and psychiatric disorders.
