Therapeutic Approaches and Online Care

Acceptance and Commitment Therapy (ACT) emphasizes learning to accept difficult thoughts and feelings while taking action that aligns with personal values. It can be helpful for anxiety, stress, depression, and patterns that keep people stuck.

Attachment-Based Therapy focuses on how early relationships shape current ways of relating to others. It supports work on intimacy, abandonment concerns, relationship patterns, and building more secure connections.

Cognitive Behavioral Therapy (CBT) helps people identify and change unhelpful thinking and behavior patterns. It is widely used for anxiety, depression, coping with life changes, and many day-to-day stressors.

Finding the right approach is part of the therapeutic process. Dr. Andrew Mendonsa works collaboratively with clients to explore which methods best match their needs, goals, and preferences, and adjusts strategies over time based on progress and feedback.

Online therapy offers practical flexibility - sessions by video call or phone allow real-time conversation, while live chat and text-based messaging provide options for shorter check-ins or ongoing support between appointments. These formats make it easier to fit therapy into busy schedules, support international clients, and maintain continuity of care when in-person sessions are not possible.
