About Mari

Mari DeRienzo is a licensed professional counselor with 39 years of experience. She helps people facing stress, anxiety, relationship and parenting challenges. She offers a calm, nonjudgmental presence for people beginning therapy and acknowledges that starting is often the hardest step.

Mari creates a space where clients can speak openly about thoughts and feelings. She focuses on listening first and understanding each person's goals. Conversations are paced to match what the client needs in the moment.

Her approach draws on several practical methods. Cognitive Behavioral Therapy helps people notice unhelpful thoughts and try different responses. Client-Centered Therapy centers the client's experience and priorities. Motivational Interviewing supports change by exploring and strengthening what matters to the client.

Mari also uses Solution-Focused Therapy to break problems into manageable steps and Internal Family Systems to look at different parts of a person’s inner life. Together these methods aim to make daily coping easier and to clarify next steps for relationships and parenting concerns.

She has worked in New Jersey settings over many years and brings that long-term experience to each session. Mari encourages people to take modest, practical steps and to measure progress in ways that fit their life.

How her approaches translate to online work

Mari commonly uses Client-Centered Therapy and Cognitive Behavioral Therapy in her practice. Client-Centered Therapy emphasizes listening and following the client's lead, which helps people feel heard and decide what to focus on. Cognitive Behavioral Therapy looks at thoughts and behaviors and teaches practical skills to change unhelpful patterns.

Finding the right approach is part of the work together. The therapist will talk with each person about goals and preferences, and will try methods that match those needs. That makes sessions collaborative and tailored rather than one-size-fits-all.

Confirm the specific session formats before booking, as the biography does not list them. Online therapy can make it easier to fit sessions into a busy life, for example by reducing travel time, allowing check-ins during a break, or offering options that don't require being on camera. Licensed professionals can adapt CBT exercises and client-centered conversations to remote settings so progress can continue even when schedules are tight.

Before you get in touch

Therapists listed here offer talking therapy online. A profile is not a diagnosis of you or of anyone in your life, and no therapist can promise how a relationship will turn out.

If you are in danger, or someone is hurting or threatening you, contact emergency services or a domestic-abuse helpline. The numbers are at the foot of this page.
