Meet Diane Necastro
A compassionate therapist who believes meaningful change begins with a trusting therapeutic relationship.

Therapy that honors your experience and your pace
As a licensed clinical social worker, Diane works with individuals and families facing personal life challenges. These may include concerns related to relationships, work, school, health, loss, grief, anxiety, depression, trauma, stress, and difficult life transitions.
Her approach is collaborative and strengths-based, focusing on each person’s natural inclination to move toward health and balance. Therapy can provide an opportunity to support change, growth, and a deeper understanding of the choices that affect both you and the important relationships in your life.
Diane’s training is in structural family therapy. She integrates emotion-focused, attachment-based, mindfulness-based, and Cognitive Behavioral Therapy interventions, adapting treatment to each client’s needs, strengths, values, and goals.
Diane welcomes the opportunity to help you take that next step with clarity and support.
