Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor in Illinois with 35 years of practice. She presents a calm, attentive presence and focuses on listening closely to each person who seeks help. Her approach values each person's beliefs and life situation, including issues around gender and spirituality.

She helps people dealing with mood concerns such as depression and bipolar disorder, and with anxiety, grief, trauma, and addictions. Relationship concerns, intimacy issues, parenting stress, and anger are also part of her work. She draws on a broad set of clinical approaches to match the needs a person brings to therapy.

Her style is respectful and nonjudgmental. She pays attention to a person’s support system and how relationships affect wellbeing. Practical steps and increased awareness are part of the process she uses to help people cope with life transitions and stress.

People who value a therapist who honors faith and identity often find her approach a good fit. She aims to work with each person where they are and to support clearer thinking, steadier mood, and healthier relating.

Approaches that shape online sessions

Acceptance and Commitment Therapy (ACT) focuses on helping a person notice unhelpful thoughts and commit to actions aligned with their values; it can help with anxiety, depression, and managing anger. Attachment-Based Therapy looks at how early and current relationships influence feelings and behavior, which can be useful for intimacy issues, caregiving stress, and relationship patterns. Client-Centered Therapy emphasizes listening, empathy, and respect so the person can set the pace and topics for change.

Finding the right approach is part of the work. The therapist will talk with each person about goals and preferences and together decide which methods to try. That collaborative process is ongoing and can be adjusted as needs change.
