M Tirtza Katz and Dvora Philip

Miriam Tirtza Katz holds a degree in psychology with a specialty in special education. She is a Certified Teacher of the Handicapped. Tirtza is dually certified in DIR/Floortime with ICDL Advanced DIRFloortime Certification and certification through Richard Solomon’s PLAY Project. She is also training for infant mental health endorsement through NJ-AIMH. Tirtza currently works as a classroom-based DIR/Floortime supervisor in the School for Children with Hidden Intelligence. She also works privately with children and families struggling with Autism and other developmental disabilities. Tirtza is passionate about the study of Infant Mental Health, the intersection of trauma and development, and maintaining a whole child approach to intervention. Her work’s experience has been richly enhanced by many talented and knowledgeable mentors and guides to who have shaped and inspired her work. Tirtza’s accomplishments include: creating and implementing a comprehensive model for DIR in classrooms, creating and maintaining a data system for play based work, and most importantly, supporting families and individuals as they face the daily challenge of developmental disabilities. Dvora Phillip is a practicing Board Certified Behavior Analyst (BCBA). Dvora received her master’s degree in general psychology and post- graduate certification as a BCBA. Dvora has a certification in DIR Floortime, from Profectum Foundation. Dvora is currently practicing as a BCBA in her private practice, Joy Therapeutics. It was Dvora’s education of the science of behavior analysis and that of psychology that gave her the perspective of incorporating both the science and the emotional component in her work. She was fortunate to work with many talented professionals, mentors, and professors from whom she learned a tremendous amount. As an ABA therapist, and later as a BCBA, Dvora would sit with developmental therapists and observe their work, while breaking it down into behavioral terminology for herself. She saw that their approach often worked to create robust interactions, and she wanted to understand why this worked behaviorally. Dvora’s passion is approaching children from a perspective of behavior, emotions, and development. She especially enjoys working with children and their parents together. Dvora’s accomplishments include creating play-based behavior analytic treatment plans, and helping children progress towards a more joyful, confident and successful future.
