About Mari
She creates a calm space where clients can talk about their thoughts and feelings without judgment. Sessions focus on what matters most to the person sitting in the room. Mari listens, asks clear questions, and helps people find practical steps forward.
Her work covers a wide range of concerns including grief, self-esteem, coping with life changes, and compassion fatigue. She also supports people navigating ADHD, substance issues, communication problems, and complicated family or fatherhood dynamics. She is open to discussions about less common issues such as kink and alternative sex culture when those topics are relevant to a client.
Mari uses familiar therapeutic methods to help people make change. She draws on client-centered approaches, cognitive behavioral ideas, motivational interviewing, solution-focused techniques, and Internal Family Systems concepts. Those methods are used to match what each person needs in the moment.
She practices in New Jersey and speaks English. If someone is ready to start, the process begins by selecting the Start Therapy button, completing a short matching questionnaire, and then scheduling according to therapist availability.

How therapeutic approaches translate online
Client-Centered Therapy focuses on listening and building trust so clients can say what matters most. Online sessions allow the therapist to reflect and respond in ways that help people feel heard and understood. Cognitive Behavioral Therapy (CBT) breaks problems into thoughts, feelings, and actions and then tries small experiments to change unhelpful patterns. CBT work online can include setting homework, reviewing thought records, and practicing new skills between sessions.Finding the right approach is part of the work together. The therapist will talk with the client about goals, needs, and preferences and then suggest methods that fit. Decisions about which techniques to use happen through discussion and testing what helps most in real life.
Confirm current session options before booking to know which remote formats are offered. Online work can make it easier to fit therapy into a busy day, allow a shorter check-in when needed, and reduce travel time. It also lets clients use tools like worksheets and screen sharing during a session to support skill practice and problem solving.
