Therapeutic Approaches and Online Care

Donald Cassidy commonly uses Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT), along with Internal Family Systems (IFS) when appropriate. CBT focuses on identifying and changing unhelpful thinking and behavior patterns to reduce symptoms of anxiety, depression, and stress. DBT combines skills training in emotion regulation and interpersonal effectiveness to help with overwhelming emotions, relationship struggles, and coping under pressure. IFS explores the different internal parts of a person to promote self-awareness and healing from trauma or persistent inner conflict.

Finding the right approach is part of the therapeutic process, and Cassidy collaborates with each person to determine which methods fit their goals, needs, and preferences. This collaborative process allows adjustments over time so therapy remains responsive to progress and changing priorities.

Online therapy options include video calls, phone sessions, live chat, and text-based messaging, offering flexibility for scheduling and access from home or work. These formats make it easier to maintain consistent care around busy lives, provide timely support between sessions, and expand access to licensed professionals without requiring travel.
