Online support

Attachment-informed care and practical online therapy

Dr. Mendonsa uses attachment-based ideas to notice how past and current relationships shape emotional responses and patterns. That approach helps people who struggle with intimacy, abandonment worries, or difficulty trusting others to see where their reactions come from and to practice different ways of connecting.

He also integrates Acceptance and Commitment Therapy, which focuses on clarifying values and taking action even when emotions are hard, and Client-Centered Therapy, which makes the work collaborative and paced to the person's needs. ACT helps with living a meaningful life despite anxiety or low mood, while client-centered work keeps sessions focused on what matters most to the person.

Finding the right mix of approaches is part of the work. He will collaborate with each person to choose tools that fit their goals, preferences, and everyday life. The plan can change as progress is made or new needs appear.

Online formats include video calls, phone sessions, live chat, and text-based messaging to fit different schedules and comfort levels. Video is useful for full sessions and nuanced conversation, phone can be a lower-bandwidth option, and messaging or chat can support quick check-ins or between-session coaching. These choices make it easier to fit therapy into work, caregiving, or busy lives while keeping the focus on practical change and stronger relationships.
