Evidence-Based Therapy Approaches, Made Accessible Online
Donald Cassidy draws from evidence-based therapeutic techniques and offers several well-known approaches that can be effective for concerns like anxiety, depression, stress, and ADHD. Cognitive Behavioral Therapy (CBT) focuses on identifying unhelpful patterns in thoughts and behaviors and practicing new skills to support day-to-day coping, confidence, and follow-through. Dialectical Behavior Therapy (DBT) builds practical tools for emotion regulation, distress tolerance, and interpersonal effectiveness, which can be especially helpful when stress feels intense or relationships feel strained. Motivational Interviewing is a collaborative, goal-focused style that helps clarify what matters most and strengthen follow-through when change feels complicated or stuck.Because people respond differently to therapy, finding the right fit is part of the process. Donald works collaboratively with clients to select an approach based on current concerns, goals, and personal preferences, and he can adjust the plan as needs evolve over time.
Online therapy also makes it easier to get support in a format that fits real life. Sessions may take place through video calls or phone sessions, with additional options such as live chat or text-based messaging. This flexibility can support consistent engagement, whether clients prefer face-to-face conversation or a more written, between-session style of communication.
