What I like most about Washington University Child Psych: My interview was my first time ever in Missouri and I had no connections to St. Louis. Starting from dinner through the interview day, I was struck by the warmth and authenticity of everyone I met, from the fellows to the faculty interviewers. Our program offers many rotations that are rare in child psychiatry: residential eating disorders, a long-term state hospital, infant psychiatry, etc. The clinical training is diverse and challenging enough that I’m confident I can handle anything after graduation. The faculty are very approachable, brilliant, and support us individually and from an administrative level. As a transplant to St. Louis, I’ve it found it to be very charming and affordable, with surprisingly little traffic. It’s a city of many old neighborhoods with plenty of character and gorgeous architecture, an explorer and history buff’s delight. WashU Child Psychiatry is an exceptionally strong program in an underrated city.

They really support you as an individual rather than forcing you onto a specific career path.
