PD Monster is your go-to source for
Professional Development for educators!

Our Philosophy

We believe that adult beliefs, attitudes, and actions are what have the greatest impact on student outcomes. We believe that every small change in adult practice leads to big improvements in school experiences for students.

Our Mission

At PD Monster, our mission is to provide practical training & coaching that educators can use immediately to improve their practices. Our goal is to help schools provide meaningful educational experiences for all students by enhancing the capacity of staff to support students, solve problems, and work as effective team members.

Our Services

We offer professional development in a variety of formats for administrators, teachers, school-based clinicians, and support staff. In-district training, coaching, and systems development services are available virtually or in-person (depending on availability in your location). We also offer webinars and online courses throughout each school year on a wide variety of topics. See tabs above for more information.


PD Monster is certified by multiple professional agencies, such as NASW, NASP, and the BACB to offer continuing education credits to education professionals. Each webinar or online course specifically details the accreditations for each session.  Please read carefully before you register.
