About Gabriele Educational Materials & Systems

For over 40 years, GEMS has served the education community. The company’s initial emphasis was on English Language Learners, and their first publication, “The Verb Chart Bulletin Board,” was selected for the LAUSD Secondary Audiovisual Recommended Materials List. Over the years, GEMS widened its purpose to serve the whole school community and provide systemic solutions to meet the increasing complexity and changing needs of schools, workplaces, and society. For the last 20 years, GEMS has been developing an exciting program, the GEMS RoundTable. With the RoundTable, GEMS aims to help schools and workplaces as they seek more effective ways to enrich, renew and transform their organizations while improving participant learning, performance and satisfaction. Today GEMS clients are national and international.

Executive Director Sue Gabriele has over 40 years experience in the education field. After studying school organization theory at UCLA and language, literacy and learning at USC, Sue received her Ph.D. in “Human Science: Social and Institutional Change” from Saybrook Research Institute underpinned by a theoretical framework of systems thinking, systemic change and systemic renewal. Prior to her graduate work, Sue spent 20 years as a classroom teacher in elementary, middle, and high schools, as well as junior colleges. Her years in LAUSD included responsibilities as mentor teacher, ESL and Foreign Language department chair, and teacher trainer. Sue also taught educational research methods at Chapman University in Manhattan Beach. Sue is also a certified instructor of Thomas Gordon’ Effectiveness Training, Inc., focusing on Personal and Professional Effectiveness, No-Lose Conflict Resolution, and Teacher Effectiveness Training.

GEMS is available for workshops, coaching and training. We can provide one of our existing programs, customizing it with you for your purposes. We can also do a needs assessment of your organization with you, and design a program drawing from our combined expertise and all of our programs.

Or, you may simply want to add a monthly 30/30* RoundTable to your existing structures and procedures! *30/30 = A session lasts 30 minutes; Everyone present (e.g., 30 people) is offered equal time to speak.
