About Mari

Mari DeRienzo is a Licensed Professional Counselor (LPC) with 39 years of experience. She helps people facing stress, anxiety, intimacy-related concerns, parenting struggles, and grief. She aims to create a calm, open space where clients can share thoughts and feelings without judgment.

Her approach is practical and straightforward. She listens first, then helps people set small goals that feel doable. She uses client-centered methods to follow each person’s pace and preferences. She also draws on Cognitive Behavioral Therapy to spot and change unhelpful thinking patterns.

Mari uses Motivational Interviewing to help people find their own reasons for change. She applies Solution-Focused techniques to identify what is already working and build on it. Internal Family Systems ideas help name the different parts of experience and how they relate to each other.

She has worked across many concerns over her career, including stress, addiction, communication problems, and issues related to kink and alternative sex culture. She also supports work on compassion fatigue, first responder issues, and fatherhood challenges. Her experience includes helping people manage life transitions and rebuild self-esteem.

Mari is based in New Jersey and provides services in English. She welcomes international clients and asks people to complete a short matching questionnaire to get started. To begin, select the Start Therapy button and schedule according to therapist availability.

How Marian approaches therapy online and by method

Client-Centered Therapy puts the person’s experience first. The therapist listens without judgment and follows the client’s lead to set goals and pace. This approach is useful for people who want a supportive space to talk through feelings and decisions.

Cognitive Behavioral Therapy, or CBT, focuses on identifying thoughts and behaviors that keep problems going. It uses practical exercises to test ideas and build different habits, which can help with anxiety, stress, and low self-esteem.

Motivational Interviewing helps people clarify their own reasons for change. It’s a collaborative, gentle method that encourages small steps and real-world choices when someone feels stuck.

Choosing an approach is part of the work. The therapist will talk with each person about their goals, try methods that fit, and adjust based on what helps most. This is a collaborative process where client preferences guide decisions.

Confirm the current session formats before booking so you know what’s available. Online care can make it easier to fit sessions into a busy week, reduce travel time, and allow shorter check-ins when needed. Licensed professionals can use these options to keep therapy practical and consistent without promising a specific format.
