About Mary
Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor (LCPC) practicing in Illinois with 35 years of experience. She approaches therapy as a personal journey toward greater well-being and listens closely to what each person brings to the room. Her manner is patient and nonjudgmental, and she aims to treat a person’s concerns with attention and respect.
Her work covers many everyday difficulties, including stress, anxiety, depression, grief, addictions, relationship problems, and issues related to LGBT identity. She also focuses on parenting challenges, compassion fatigue, career stress, and problems connected to attachment and abandonment. Adoption and foster care are listed among additional areas she attends to when relevant.
Dr. Dier-Zimmermann uses practical conversations and collaborative planning. She completes an assessment, describes options, and helps people set clear goals. Sessions often look at patterns in relationships and ways to strengthen supports that matter most in daily life.
Her approach draws on methods such as Acceptance and Commitment Therapy, attachment-based work, client-centered listening, existential reflection, and the Gottman Method for relationship concerns. She also brings training in religion and spirituality to help people fold their beliefs into therapy when that is important to them.
People meet her for help with life changes, coping after loss, managing mood concerns, and improving important relationships. She aims to create a steady, respectful space where practical steps and honest conversations move the work forward.
How her approaches translate to online care
Acceptance and Commitment Therapy (ACT) focuses on helping people notice thoughts and feelings without letting them control action, and it supports building a values-driven life. Attachment-Based Therapy looks at how early and current relationships shape emotional patterns and helps people try new ways of relating. Client-Centered Therapy centers on respectful, empathic listening and gives the person space to find their own solutions.Finding the right approach is part of the work. Dr. Dier-Zimmermann will talk with each person about what feels useful and what goals matter most. Together they decide which methods to emphasize and adapt the plan as needs and progress evolve. This makes the process collaborative rather than prescribed.
This profile does not list specific session formats, so please confirm current online options before booking. Many people find online sessions help fit therapy into a busy life by reducing travel, allowing appointments during a lunch break, or making it easier to connect when home or work schedules are tight. Online meetings also let therapists and clients bring materials, notes, or worksheets into the session easily, and can make follow-up check-ins shorter and more focused when needed.
