About Mary
Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor in Illinois with 35 years of experience. She focuses on helping people facing stress, anxiety, depression, trauma, addiction, and relationship challenges.
She brings a calm, attentive presence and respects each person's beliefs and life story. She listens closely and uses that understanding to build a plan together. Sessions often include checking current struggles, identifying practical next steps, and strengthening close relationships and support systems.
How Mary works
The goal is steady, realistic progress rather than quick fixes. Her background includes study of religion, spirituality, and psychology, and she helps people consider how faith or spiritual beliefs interact with mental health. That can mean talking through values, meaning, and how beliefs fit into daily choices and coping strategies.
Dr. Dier-Zimmermann uses approaches that emphasize personal values, emotional connection, and clear communication. She helps clients learn skills to manage intense emotions, improve intimacy, and handle life transitions.
She also addresses specific areas such as parenting strain, caregiving stress, grief, and body image concerns. In sessions she aims to be nonjudgmental and supportive. People work at a pace that fits them, and the therapist adjusts strategies as needs change.
For someone needing steady, experienced guidance through a difficult period, she offers a thoughtful, respectful approach.

Online support options
How her methods translate to online therapy
Dr. Dier-Zimmermann draws on Acceptance and Commitment Therapy and Attachment-Based Therapy in her online work. ACT focuses on identifying personal values and taking small steps toward them while learning to live with difficult thoughts and feelings; it can help with anxiety, depression, and coping with life changes. Attachment-Based Therapy looks at how early relationship patterns affect current connections and helps people build clearer, healthier ways of relating to others.Finding the right approach is part of the work. She will talk with each person about goals, preferences, and what feels most useful. Together they decide which methods and exercises to try and adjust them as progress is made.
Online sessions are offered by video calls, phone sessions, live chat, or text-based messaging to increase flexibility. Video calls allow for face-to-face conversation, phone sessions can work when bandwidth is low or a camera feels unnecessary, and chat or text can fit brief check-ins or times when typing is easier. These options make it simpler to fit therapy into a busy schedule and to keep continuity when life gets disrupted.
