Festschrift for Leonard Bickman: Introduction to The Future of Children's Mental Health Services Special Issue.

This introductory article describes the genesis of the Festschrift for Leonard Bickman and of this Festschrift special issue entitled, The Future of Children's Mental Health Services. The special issue includes a collection of 11 original children's mental health services research articles, broadly organized in accordance with three themes (i.e., Improving Precision and Use of Service Data to Guide Policy and Practice, Implementation and Dissemination, and Preparing for Innovation), followed by an interview-style article with Bickman. Then follows a featured manuscript by Bickman himself, three invited commentaries, and a compilation of letters and notes in which colleagues reflect on his career and on their experiences of him. The introduction concludes with a few thoughts about the future of children's mental health services portended by the extraordinary scholarly contributions of Bickman and those who have been inspired by him.
