About Mari

Mari DeRienzo is a Licensed Professional Counselor (LPC) practicing in New Jersey with 39 years of experience supporting people facing stress, anxiety, family conflict, intimacy concerns, parenting challenges, grief, and related life changes.

Background and approach

She blends practical strategies with empathic listening to help clients explore what matters most to them and develop concrete steps for coping and growth. Her approach emphasizes collaboration and respect for each person’s priorities.

Mari uses evidence-informed methods such as Cognitive Behavioral Therapy (CBT) alongside client-centered listening, motivational interviewing, solution-focused techniques, and Internal Family Systems perspectives to tailor work to an individual’s needs. She aims to create a nonjudgmental space where thoughts and feelings can be explored and where realistic goals and small experiments lead to forward movement.

In addition to common concerns like self-esteem and anger, Mari addresses a wide range of focused topics including relationship communication, codependency, addiction, ADHD, and aspects of alternative sexual culture. Sessions are available online in multiple formats, and she is open to international clients while practicing under her New Jersey LPC credentials.

Using Evidence-Based Approaches in Online Care

Mari integrates Cognitive Behavioral Therapy and Client-Centered Therapy in her online work. CBT focuses on identifying unhelpful thinking patterns and trying practical behavioral experiments to reduce symptoms like anxiety and stress. Client-centered therapy emphasizes empathic listening and collaboration so clients feel heard while they explore their values and goals.

She also draws on Motivational Interviewing to support change when ambivalence is present by helping clients clarify motivation and commit to achievable steps. Choosing the right approach is a shared process - the therapist works with each client to decide which methods fit their priorities, goals, and preferences and adapts over time based on what helps.

Online therapy offers flexible access through video calls, phone sessions, live chat, or text-based messaging, making it easier to fit sessions into busy schedules or to continue work across locations. These formats support regular check-ins, skill practice between sessions, and a variety of communication styles so clients can engage in the way that feels most workable for them.
