About Mari
Mari DeRienzo is a licensed professional counselor with 39 years of experience who helps people facing stress, anxiety, grief, and compassion fatigue. She supports those dealing with parenting struggles, intimacy-related concerns, and self-esteem issues. Mari aims to make the first step easier by offering a calm, nonjudgmental space to talk.
Clients can expect straightforward conversations that focus on what matters most to them. She uses practical methods to help people manage emotions and solve immediate problems.
How Mari works
Sessions are collaborative and paced to each person’s needs. Mari combines client-centered work with cognitive behavioral techniques to identify unhelpful thoughts and change patterns that cause distress. She also uses motivational interviewing to support readiness for change and solution-focused strategies to set clear, short-term goals.
For longer-standing internal conflicts, she draws on Internal Family Systems to map different parts of a person’s inner life and create more internal cooperation. This mix of approaches helps with a broad range of concerns, from coping with life changes to substance-related issues and communication problems.
Her additional focus areas include issues such as codependency, infidelity, fatherhood challenges, first responder stress, and concerns related to BDSM and alternative sex culture. Mari practices in New Jersey and conducts sessions in English, including work with international clients when appropriate.

Online support options
Therapeutic approaches and online options that fit your life
Client-centered therapy focuses on understanding each person’s experience and building a trusting relationship. It helps people feel heard and supported while they talk through worries and decisions.Cognitive Behavioral Therapy, or CBT, looks at how thoughts affect behavior and mood. It teaches concrete skills to change unhelpful thinking and reduce symptoms like anxiety and anger.
Motivational Interviewing helps people find their own reasons to change. It is useful for issues like substance use, commitment struggles, or any situation where someone feels stuck.
Finding the right approach is part of the work. The therapist will collaborate with each person to choose methods that match their goals, pace, and preferences. That way sessions stay focused and meaningful.
Online therapy offers flexible ways to meet. Video calls allow full conversation and visual cues, phone sessions work well when bandwidth is limited, and live chat or text-based messaging supports quick check-ins or ongoing coaching between sessions. These formats make it easier to fit therapy into a busy life and to continue progress even when schedules change.
