About Mary
Dr. Mary Ann Dier-Zimmermann, LCPC, is licensed in Illinois and has 35 years of professional experience. She works with people on stress, anxiety, depression, bipolar disorder, addictions, grief, relationship and intimacy concerns, and related life changes. She describes her work in terms of listening carefully, assessing needs, and creating a plan together.
Dr. Dier-Zimmermann uses several therapeutic approaches, including Acceptance and Commitment Therapy, attachment-based ideas, client-centered methods, existential perspectives, and the Gottman Method for relationship work. Sessions aim to identify patterns, clarify values, and develop practical ways to manage emotions and behavior. She notes attention to issues such as LGBT concerns, parenting strains, caregiver stress, and compassion fatigue.
Her practice includes focus areas like abandonment, adoption and foster care, attachment issues, blended family concerns, body image, cancer-related stress, and coping after disasters. She also notes work related to dependent and avoidant personality features, dissociation, and separation or divorce. This gives a broad footprint for people facing complex or intersecting problems.
In typical sessions she provides an assessment and a plan. The plan may include practical coping strategies, relationship-focused exercises, and ways to expand a person’s support network. She draws on clients’ beliefs and life context when that is important to them.
Dr. Dier-Zimmermann practices in Illinois and conducts sessions in English. To begin, the service uses a subscription that can be canceled at any time and asks prospective clients to complete a short matching questionnaire before scheduling a first session.

Approach and what to expect from online sessions
Dr. Dier-Zimmermann uses Acceptance and Commitment Therapy (ACT) to help people clarify their values and take committed steps toward goals despite difficult thoughts or feelings. ACT can be useful for anxiety, depression, and stress when someone wants concrete ways to act in line with what matters to them.She also draws on Attachment-Based Therapy to look at how early connections influence current relationship patterns. This work is practical for people struggling with intimacy, abandonment concerns, or repeated relationship conflicts.
Client-Centered Therapy is part of her mix as well, which means sessions emphasize listening, respect for the person’s perspective, and working at the client’s pace. That approach supports people who need to explore personal beliefs, life meaning, or faith-related concerns.
Finding the right approach is part of the work. The therapist will review symptoms, goals, and preferences and then recommend which methods to try first. This decision is collaborative and can change as progress is made.
Confirm the available session formats before booking because the biography does not list specific online or in-person options. Online work can make it easier to fit sessions into busy days, reduce travel time, and allow shorter check-ins when needed. Licensed professionals can adapt ACT, attachment work, and client-centered methods to remote sessions to focus on skills, relationship patterns, and values-based action without changing the core therapeutic aims.
