Meet Dr. Dianne:
Owner of Dianne's Consultant Services

Dr. Dianne DeMille has over 40 years’ experience in mathematics education, including teaching, county administration, and graduate level professor. During the first 20 years of her career, she taught almost every math course offered in middle and high school, including AP Calculus. Dianne found that many students felt incompetent and anxious about learning math. Students who were the lowest and highest performing made comments about their insecurities, even those in honors and AP courses. We have all heard the stories from parents and colleagues about their experiences in school and learning math.

For the next 19 years, while serving as coordinator at the Orange County Department of Education, Dr. Dianne assisted in coordinating district and site mathematics instruction to meet the needs of all learners (stressing increased achievement for English Language Learners, Hispanic Students who are not English Learners, and Economically Disadvantaged Students). She served as the state coordinator for the Golden State Exams in three areas of Mathematics, was Co-PI for a NSF-MSP Phase I & II grant, served as an expert panelist for the National Commission on Teaching and America’s Future report presented on June 24, 2011 at the US Congressional Briefing, was appointed Conference Coordinator (2011-2015) for NCSM, and named National Association of Professional Women, Professional Woman of the Year, Innovative Educator with a Vision to Serve Underprivileged Communities. 

Dr. Dianne continues to use her extensive abilities as a consultant for administrators, coaches, teacher leaders, and teachers of mathematics for diverse populations. She is a mathematics consultant with Solution Tree and Pivot Learning doing professional development, coaching, and support for professional learning communities (PLCs).
