About Matthew

Matthew Garthwait is a licensed clinical social worker in New Hampshire with 22 years of professional experience. He offers supportive, down-to-earth care for people facing stress, anxiety, addictions, grief, low self-esteem, and major life changes. Matthew emphasizes practical steps and steady support so people can move toward more fulfilling days.

He starts by treating each person as the expert on their own life. Sessions focus on identifying strengths and small, doable changes that build confidence and reduce overwhelm. Matthew listens for what matters most and helps shape goals that fit real life.

Over two decades of practice have included work with drug and alcohol addiction, process addictions like gambling or compulsive sexual behavior, smoking and vaping cessation, and recurring panic or social anxiety. He also supports men dealing with fatherhood challenges, impulsivity, and questions about life purpose. Isolation and loneliness are among the concerns he helps address.

Matthew keeps language simple and clear during sessions. He tends to break problems into manageable steps and checks in on what is working. People who want honest, practical guidance about change often seek him out.

To begin, a prospective client completes a short matching questionnaire and schedules sessions based on therapist availability. Sessions use a subscription that can be canceled at any time, and fees vary with location and therapist availability.

How Matthew’s approaches work in online therapy

Matthew uses evidence-based therapeutic techniques focused on practical change and coping skills. One common approach is skills-based work that teaches actions for managing anxiety, panic, and overwhelming stress. This kind of work breaks symptoms into specific tools you can try between sessions to notice small improvements.

Another frequent element is relapse-prevention style planning for addictions and process behaviors. That involves identifying triggers, building routines, and creating step-by-step responses to urges. It helps people plan for setbacks and sustain progress over time.

Choosing the right approach is a collaborative process. Matthew will talk with clients about goals, preferences, and what has or hasn’t helped before. Together they decide which techniques to try and adjust them as needed so the work fits everyday life.

Session formats are not specified in the biography, so confirm current options before booking. Online work can make it easier to fit therapy into a busy schedule, allow shorter check-ins when useful, and reduce travel time. Licensed professionals often use these practical benefits to help clients maintain momentum between appointments.
