About Mary
Dr. Mary Ann Dier-Zimmermann is an Illinois Licensed Clinical Professional Counselor (LCPC) with 35 years of clinical experience. She works with adults on common life struggles such as stress, anxiety, depression, grief, relationship concerns, parenting strain, and blended family issues. Sessions are offered in English and focus on practical steps clients can take day to day.
Her style is direct and person-focused. She listens and helps people identify immediate priorities. Typical concerns include coping with life changes, addiction-related patterns, intimacy questions, and career stress. She also addresses issues connected to attachment, abandonment, adoption and foster care, and caregiving stress.
Dr. Dier-Zimmermann draws on approaches that include Acceptance and Commitment Therapy, Attachment-Based Therapy, Client-Centered Therapy, Existential Therapy, and aspects of the Gottman Method. In session she uses these tools to help people clarify values, notice relationship patterns, and test small changes. Conversations are practical and aimed at changes that fit everyday life.
She offers assessment and a plan early in the work so goals are clear. Spiritual or religious questions can be part of sessions when clients want that included. The focus remains on what clients want to change and how to build supports that make those changes possible.
People in blended households who are managing stepfamily roles, co-parenting tensions, loyalty conflicts, or merged routines may find her perspective relevant. Before booking, confirm current session options and formats.
How her approaches are used in online sessions
Acceptance and Commitment Therapy (ACT) helps people notice what matters to them and take small steps toward those values. It is useful for anxiety, depression, and life transitions where choosing actions matters more than perfect feeling control.Attachment-Based Therapy focuses on how past and current relationships shape reactions. It helps people understand patterns of closeness and distance and work toward steadier connection in everyday relationships.
Finding the right approach is part of the work. The therapist collaborates with each person to pick methods that match their goals, preferences, and the problems they bring. Treatment plans are adjusted over time based on what helps most.
Session formats are not listed in the biography, so confirm current online options before booking. Online work can make it easier to fit sessions into daily life, shorten commute time, and allow quicker check-ins between meetings. It also lets people try approaches such as values-based experiments or communication skill practice from their usual routines, which can speed up learning and make changes easier to test.
