Therapeutic Approaches and Flexible Online Care

Acceptance and Commitment Therapy (ACT) helps people notice difficult thoughts and feelings without getting stuck in them, then identify personal values and take committed steps toward a meaningful life. It is often used for anxiety, stress, and coping with life transitions. Attachment-Based Therapy focuses on patterns of relating and connection formed early in life and explores how those patterns shape adult relationships, intimacy, and trust. Client-Centered Therapy emphasizes empathetic listening and support, giving clients space to discover their own solutions and build self-direction with the therapist as a collaborative partner.

Finding the right approach is part of the therapeutic process. Dr. Mendonsa works collaboratively with clients and licensed professionals to identify which methods best fit an individual’s needs, goals, and preferences, adjusting the plan as progress unfolds.

Online sessions offer practical flexibility - Dr. Mendonsa provides video calls, phone sessions, live chat, and text-based messaging - making it easier to access therapy from different locations and to maintain continuity during busy schedules or life changes. These options support consistent engagement while allowing each person to choose the format that works best for them.
