About Mary
Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor who has worked in Illinois for more than 35 years. She focuses on helping people move through anxiety, depression, grief, relationship stress, and issues connected to identity and life change.
She aims to listen closely and treat each person with respect and care. She describes healing as a process toward feeling whole, peaceful, and more able to enjoy life. Sessions often begin with an assessment and a simple plan.
Background and approach
From there she and the client look at practical steps and ways to expand awareness and strengthen support systems. Her background includes study of religion, spirituality, and psychology, and she uses that knowledge when faith or meaning are part of a person's concerns. She honors a person's beliefs and gender orientation and works to integrate those aspects into therapy when helpful.
Her approach is collaborative and down-to-earth. Conversations can cover relationships, family stress, parenting strains, career concerns, addiction, trauma, or changes from illness or loss. She also addresses issues such as abandonment, attachment challenges, body image, and caregiving stress.
In the therapy room she aims for attention, compassion, and nonjudgmental listening. The work can include exploring personal meaning, strengthening relationships, and building coping strategies for day-to-day life. People leave with clearer steps and a better sense of direction.

Online support
Approaches that translate to online care
Jungian-informed work looks at symbols, personal stories, and life patterns to help people find meaning and deeper self-understanding; this can be useful for clients exploring identity, spirituality, or long-term patterns. Acceptance and Commitment Therapy, or ACT, focuses on noticing thoughts and feelings while taking actions that match personal values, which helps with anxiety, depression, and coping with change. Attachment-Based Therapy looks at how early connections shape current relationships and can help with intimacy, trust, and family-related stress.Finding the right approach is part of the process. The therapist will work together with each person to choose methods that match their needs, goals, and preferences. That collaborative planning can include trying different ways of working and adjusting over time as needs shift.
Online formats include video calls, phone sessions, live chat, and text-based messaging to fit different schedules and communication styles. Video lets people see facial cues during deeper conversations, phone calls work well when bandwidth is limited, live chat can be used for shorter check-ins, and text messaging supports brief ongoing contact between sessions. These options make it easier to fit therapy into work, caregiving, or travel schedules while keeping continuity of care.
