About Mary
Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor practicing in Illinois with 35 years of experience.
Background and approach
She focuses on helping people navigate stress, anxiety, depression, grief, addiction, relationship concerns, and a wide range of life changes. Dr.
Dier-Zimmermann listens with attention and respects each person’s life story and beliefs. She offers a straightforward, compassionate approach.
Sessions begin with an assessment and a clear plan that fits each person's goals. Therapy sessions cover emotional struggles, intimacy-related issues, parenting concerns, and the practical steps people can take to feel steadier.
Her work draws on relationship-focused methods, including the Gottman Method, and therapies that emphasize values and connection. These approaches help with communication patterns, attachment concerns, and aligning actions with what matters most.
Dr. Dier-Zimmermann also attends to identity and life-stage issues.
She supports people facing LGBT concerns, caregiver stress, adoption and foster care questions, aging issues, cancer-related distress, and transitions like divorce or separation. She pays attention to how beliefs and spirituality may fit into healing.
People can expect a kind, nonjudgmental space where their integrity is honored. The therapist combines listening with practical steps and collaborative planning so clients can build stronger relationships and clearer day-to-day coping skills.
How relationship work and values-based therapy translate online
Dr. Dier-Zimmermann often uses the Gottman Method to look at how partners communicate and manage conflict, focusing on practical skills for improving conversations and connection. Acceptance and Commitment Therapy, or ACT, helps people notice their values and take small actions that match those values to reduce avoidance and build meaningful routines.Choosing an approach is part of the work together. The therapist will discuss options, try techniques, and adjust plans based on what a person needs and prefers. This collaborative process helps identify which methods feel most useful for relationship patterns, anxiety, grief, or life transitions.
Online sessions are offered through video calls, phone sessions, live chat, or text-based messaging to make therapy more flexible. Video lets people practice communication skills in real time. Phone sessions can be a good shorter option or when bandwidth is limited. Live chat or text messaging support quick check-ins, homework, or ongoing support between longer sessions.
