About Matthew

Matthew Garthwait is a Licensed Clinical Social Worker (LCSW) practicing in New Hampshire with 22 years of professional experience. He works with people facing stress, anxiety, addictions, grief, self-esteem concerns, and life changes. Matthew describes clients as the experts in their own stories and focuses on practical steps people can take to manage challenges.

He uses straightforward conversations to identify what is most difficult right now. Sessions often focus on clear goals such as reducing panic symptoms, managing urges around substances or behaviors, or rebuilding confidence after loss. He listens for strengths and habits that can be used as part of change rather than starting from scratch.

Matthew helps people break larger problems into small, manageable steps. He may work on skills for coping with strong feelings, planning for behavior change like smoking or vaping cessation, or strategies to reduce isolation. For social anxiety and phobia he pays attention to the specific situations that feel triggering and to the thoughts and actions that maintain avoidance.

Over two decades of practice have included supporting people through fatherhood issues, impulsivity, and finding purpose after transitions. He combines practical problem solving with attention to everyday routines that affect mood and behavior. Sessions aim to make change feel doable rather than overwhelming.

People who choose to work with him complete an initial match and schedule a first session. Fees vary by location and sessions use a subscription model that can be canceled at any time. Sessions are conducted in English and international clients are not accepted.

How therapeutic methods translate to online sessions

The therapist uses evidence-based therapeutic techniques to guide sessions. One common approach focuses on identifying and changing unhelpful thoughts and behaviors that keep anxiety and panic going, which helps with panic attacks and social anxiety by building step-by-step practice. Another approach emphasizes skill building for coping with cravings and impulsive behaviors, supporting work on drug and alcohol addiction as well as process addictions and smoking cessation.

Finding the right approach is part of the work. The therapist will collaborate with each person to try methods that fit their needs, goals, and preferences. That means experimenting with practical exercises and adjusting techniques as progress and obstacles become clearer.

Confirm the exact session formats before booking, as session options are not specified in the biography. Online work can make it easier to fit sessions into a busy week, reduce travel time, and allow shorter check-ins when schedules are tight. It can also let someone join from a quieter space without being on camera, or choose a format that needs less bandwidth. Therapists and licensed professionals typically use these options to help sessions fit into everyday life rather than requiring large blocks of time.
