He specializes in Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT), which are the gold-standard, evidence-based approaches for treating a variety of clinical disorders. Before making aliyah, he served as a clinical psychologist and supervisor at Cognitive Behavioral Associates (CBA), a group private practice in Great Neck, NY, which is co-directed by Ruth DeRosa, Ph.D. and Jill Rathus, Ph.D., an internationally recognized expert in both CBT and DBT and a certified DBT trainer responsible for co-developing the adolescent adaptation of DBT.

He completed his bachelor’s degree in psychology at Queens College (summa cum laude and Phi Beta Kappa) and my master’s and doctorate degrees (Psy.D.) in clinical psychology at Long Island University—Post. In his career as a clinical psychologist, he has been committed to working with some of the most difficult to engage and emotionally dysregulated clients with energy, compassion, and enthusiasm.

​While commonly treating individuals and families struggling with common, everyday issues, such as anxiety, depression, and relationship problems, he is also accustomed to treating clients who have been assumed to be beyond the pale of help because of their experiences with extreme emotional distress and suffering, and their struggles with multiple diagnoses and complex problems, including suicidality and self-injurious behavior.

​Dr. Schlager specializes in Cognitive-Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), exposure based treatments, and mindfulness based therapies, all of which are evidence-based treatment approaches that have been found to be extremely effective in treating individuals experiencing a variety of problems, including mood-related problems, substance use, eating disorders, family and relationship problems, anger, depression, and those whose difficulties include engaging in suicidal and self-injurious behavior.
