Therapeutic Approaches and Online Support



Acceptance and Commitment Therapy (ACT) helps people notice difficult thoughts and feelings without getting stuck in them, clarify personal values, and take committed steps toward a meaningful life. It can be helpful for anxiety, stress, and motivation struggles. Attachment-Based Therapy explores patterns in close relationships and how early connections influence current relationship dynamics - useful for couples issues, communication problems, caregiver stress, and attachment concerns. Client-Centered Therapy emphasizes an empathic, nonjudgmental relationship in which the therapist listens deeply and helps clients access their own solutions and strengths, supporting self-esteem and personal growth.

Finding the right combination of approaches is part of the therapeutic process. Mari collaborates with each person to identify which methods fit their needs, goals, and preferences, adjusting tools and strategies over time so the work feels practical and personally relevant.

Online therapy formats - including video calls, phone sessions, live chat, and text-based messaging - make it easier to fit therapy into busy schedules and varied life circumstances. These options offer flexibility in timing and communication style, allowing clients to connect with licensed professionals from home, during breaks, or while traveling, and to continue progress even when in-person visits are not feasible.
