Dr. Finkelstein is a clinical psychologist specializing in evidence-based treatment for mood and anxiety disorders, OCD, trauma, and emotion dysregulation.

His approach blends structured interventions with authenticity, humor, and curiosity — balancing research-driven methods with a deeply human style of practice.

He earned his doctorate in Clinical Psychology from Rutgers University, completed his predoctoral internship at Montefiore Medical Center, and a postdoctoral fellowship at Columbia University Irving Medical Center, where he later served as an Instructor in Clinical Psychology and Training Supervisor.

At Columbia’s Day Program, he provided supervision in CBT, DBT, and exposure-based interventions, and helped develop programming for emotion regulation and trauma recovery.

Dr. Finkelstein has received intensive training in Dialectical Behavior Therapy (DBT) and additional advanced training in Acceptance and Commitment Therapy (ACT), Prolonged Exposure (PE), Cognitive Processing Therapy (CPT), Rumination-Focused CBT, and the Unified Protocol.

His teaching and consultation emphasize transdiagnostic case formulation, exposure work, cognitive modification, and skills-based learning, helping clinicians integrate flexibility and creativity into evidence-based practice.

Beyond clinical work, Dr. Finkelstein is the creator of The Game of Real Life — a DBT-based card game designed to make skill use engaging and accessible — and co-founder of TheraHive, a digital learning platform for evidence-based therapy.

He is also a contributor to resources such as the DBT-PTSD manual, the Rutgers DBT-RU skills video series, and the GBAT training videos for CBT and autism.

His forthcoming book with Dr. Shireen Rizvi, Real Skills for Real Life: A DBT Guide for Stress, Emotions, and Relationships (Guilford Press, 2025), translates therapeutic principles into practical skills for everyday life.
