Dr. David Diener’s dynamic talks combine intellectual substance with accessibility and practical applicability. The academic rigor of his training and research, along with with the practical insights he has acquired over more than a decade of work in the classroom and in administration, makes his consultations valuable assets for faculty training, parent and community engagement, and school leadership development.

In addition to customized consulting and speaking services, Dr. Diener also provides semester-long or year-long coaching for administrators, including but not limited to heads of school, academic deans, heads of upper school, and deans of students. This ongoing mentoring service can be customized based on the administrator’s or school’s needs, but typically involves an initial meeting on campus with the administrator and a direct supervisor, followed by weekly or biweekly phone conversations with the administrator. Through this ongoing relationship, Dr. Diener assists administrators in setting priorities and goals, working through current issues or struggles, increasing self-awareness of their professional strengths and weaknesses, and developing an ongoing strategy for professional development. At the end of the semester or year, the administrator and a direct supervisor will receive a summary report outlining the progress made and offering suggestions for further growth.
