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 who feel stuck by listening carefully and respecting their values.
Her approach is grounded in building connection and understanding before moving to change. She uses attachment-based ideas to look at how early relationships affect current behavior and feelings. That helps with worries about intimacy, abandonment, and relationship patterns.
Background and approach
She also draws on Acceptance and Commitment Therapy to help people notice difficult thoughts and still move toward what matters to them. Her work is practical and person-centered. Sessions often begin with an assessment and a simple plan.
From there, she and the client set small, achievable steps to improve mood, cope with stress, or repair strained relationships. Dr. Dier-Zimmermann brings training in religion, spirituality, and psychology into conversations when clients want that.
She honors a person’s beliefs and gender orientation as part of care. That can be helpful for clients working through faith questions, LGBTQ concerns, or identity-related stress. She supports people dealing with depression, anxiety, trauma, grief, addiction, caregiver strain, parenting stress, career transitions, and many other life challenges.
Her style is calm, nonjudgmental, and steady, with attention to both feelings and everyday choices.

Online support
How attachment and values-based approaches work online
Attachment-Based Therapy looks at patterns of connection and how early bonds shape current relationships. Online sessions can be used to notice those patterns, practice new ways of relating, and try different interaction styles in real time.Acceptance and Commitment Therapy, or ACT, helps people clarify what matters to them and take committed action even when difficult thoughts or feelings are present. In remote sessions that can mean setting small weekly experiments and tracking what helps or gets in the way.
Finding the right approach is part of the work. The therapist will talk with each person about their needs, goals, and what feels comfortable. Together they decide whether attachment-focused work, ACT, or a client-centered style will best match the issue and the person’s preferences.
Online formats include video calls, phone sessions, live chat, and text-based messaging. Video sessions allow face-to-face conversation and role-play of relationship moments. Phone sessions can be easier when bandwidth is limited or when someone prefers not to be on camera. Live chat and text messaging work well for brief check-ins, coping tools between sessions, or for people who write more easily than they speak. These options make scheduling more flexible and can fit around work, caregiving, or medical needs.
