Background and approach

Marco uses straightforward conversation to understand what matters most to each person. Sessions are tailored to the individual rather than following a fixed script. He draws on Client-Centered approaches to build trust and on Cognitive Behavioral tools to change unhelpful patterns.

Mindfulness and Dialectical Behavior Therapy methods are added when they help a person manage strong emotions and stay grounded. Marco emphasizes respect, sensitivity, and compassion in sessions. He helps people set small, practical goals and checks in on progress as work continues.

The focus is on skills that can be used between sessions to reduce cravings, calm anger, and improve communication. People who reach out can expect a calm, direct style and a focus on what they want to change. Marco aims to empower clients to make steady progress toward clearer relationships and healthier routines.

Online support

How therapy approaches translate to online work

Marco commonly uses Client-Centered therapy, Cognitive Behavioral Therapy (CBT), and Systemic ideas to guide online sessions. Client-Centered therapy focuses on listening and building trust so people can clarify what they want to change and feel heard. CBT looks at thoughts and behaviors and teaches practical steps to reduce anxiety, mood problems, or addictive urges. Systemic ideas consider how family patterns and relationships affect the issue and help identify changes that improve how people relate to one another.

Finding the right approach is part of the work. The therapist will collaborate with each person to choose methods that match their goals, preferences, and daily life. That plan can be adjusted over time as progress and needs become clearer.

Online formats include video calls, phone sessions, live chat, and text-based messaging. Video is useful for full-session conversations and skill practice. Phone calls can fit during a work break or when less bandwidth is available. Live chat and messaging suit quick check-ins, brief coaching, or moments when typing feels easier than talking. These options make it simpler to keep a steady routine of sessions and to use therapy tools between meetings.
