Kimberly Alexander, PsyD

Kimberly Alexander, PsyD, is the director and a psychologist in the Mood Disorders Center at the Child Mind Institute. Dr. Alexander treats individuals across the lifespan, bringing a thoughtful, developmentally informed approach to care. She specializes in evidence-based treatment for depression, generalized anxiety disorder (GAD), anger, suicidal ideation and self-harm, attention-deficit/hyperactivity disorder (ADHD), autism, learning challenges, stress related to life transitions, socio-economic pressures, as well as racial and ethnic identity development.

Dr. Alexander has advanced training in cognitive behavioral therapy (CBT), rational emotive behavior therapy (REBT), and dialectical behavior therapy (DBT) — including DBT for children (DBT-C) and DBT for adolescents (DBT-A). She integrates these approaches with motivational interviewing (MI), social thinking frameworks, and collaborative problem-solving to tailor treatment to each individual.

Dr. Alexander has a background in both clinical and school-based setting, with experience in neuropsychology. In addition to conducting comprehensive neuropsychological evaluations for children and adults, she has co-authored chapters on REBT-informed group and couples therapy. This work informs her understanding of how cognitive and relational differences shape emotional and behavioral functioning.

Dr. Alexander strongly believes in fostering a collaborative therapeutic relationship. She helps patients better understand the connection between their thoughts, emotions, and behaviors while building practical skills for change. She also prioritizes regular reflection on progress toward treatment goals, believing these checkpoints help to further embolden patients and their families to make the change they desire in their lives.

At the core of Dr. Alexander’s work is a commitment to providing compassionate, evidence-based care in a supportive space that offers unconditional acceptance and allows patients and families to feel understood and empowered.
