A committed and integrated team of compassionate mental health and educational experts
Founding of Cornerstone
The founding of Cornerstone Day School in 2006 by Allan J. Blau, Ed.D., LCSW, and David Nyman, Ph.D., was the result of a collaboration of experts from the fields of both special education and structured psychiatric programming. Drs. Blau and Nyman joined forces in 2004 to start the planning of Cornerstone and the creation of The Cornerstone Experience. With their combined expertise and reputations for excellence, they began with a study of therapeutic school models across the United States and took aspects from a number of them to create the one that makes Cornerstone such a unique and innovative school.

Dr. Blau has been a leader in the field of special education for over 40 years. Educator, clinician and administrator, Dr. Blau has designed and founded numerous schools and programs for special needs children throughout the tri-state region. For many years, Dr. Blau was also the president of the National Independent Private School Association for whom he currently functions as the vice-president in charge of clinical certifications of therapeutic schools and programs. Today, Dr. Blau continues as the Founding Director at Cornerstone.

Dr. Nyman, trained as a clinical psychologist and an expert in the development and management of structured therapeutic programs, has devoted his career to creating innovative models of clinical treatment programming for both children and adults. For eighteen years, ending in 2012, he was the Executive Director of High Focus Centers (HFC). Under his leadership, HFC became the most prominent treatment delivery system in New Jersey, with extensive services for adolescents with major psychiatric and/or substance abuse problems. Dr. Nyman also led the development of Effective School Solutions, a pioneering organization founded by him with Dr. Blau, that provides mental health and related services for students at risk in many public school districts in New Jersey, Connecticut and Pennsylvania.

Letter from Our Staff
Dear Parents and Colleagues:
Cornerstone is a unique school that is making a difference for so many students and their families. Students enrolling in Cornerstone have experienced major life difficulties and come to us with negative experiences of school. We take great pride in providing our students with a new school experience, one that can make them excited about school and renew their confidence and hope for the future.
For many of our staff, the highlight of our year takes place on the Tuesday before Thanksgiving. On that day, we have a family dinner and invite everyone, both students and staff, to speak about something for which they are grateful. The number of students who talk about being a part of the Cornerstone family never ceases to move us. We can honestly tell you that day alone makes all of the hard work we do during the course of the year well worth it. We welcome your interest in our school. Please come visit us and see for yourself why Cornerstone is so special.
Sincerely,
The Staff at Cornerstone
