Experience developing and implementing elementary math training modules for innovative, research-based math programs — now available to you and your teachers.

I was an elementary math teacher and administrator for 10 years. After that, I spent many years working with the authors at UCSMP to deliver standards-based math materials to millions of students. When it was first published and adopted in the early 2000s, specifically in the New England states, Everyday Mathematics was the most widely adopted and successful program at the time. Now that acceptance has shifted to another problem-based curriculum, IM Math K-5™.

I joined the Illustrative Mathematics® cadre of Certified Facilitators in 2019 and, since then, have devoted my work and attention to districts using IM Math™. Curricula built on a problem-based learning foundation have distinct, intentional elements that require specific shifts in teachers' practices. Such shifts take time and sustained focus. I'm experienced, knowledgeable, and prepared to provide the services needed to maintain that focus and meet your district's goals… long term.

Featured Program for Summer 2026 New England · IM Math K-5™

New to IM Math K-5™? Get a closer look this August.

K-5 teachers or admins who are new to IM, or teachers who simply want a closer look at the essentials of an IM lesson, are invited to join a one-day, interactive, hands-on session highlighting the essentials of problem-based teaching, held in August before back-to-school. The same agenda is offered in two locations — Cape Cod Community College on Tuesday, August 25, and the University of New England on Thursday, August 27 — specifically for those who missed their district's initial implementation training or who want a closer look.
