Dr. Mary Ann Dier-Zimmermann , LCPC

Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor (LCPC) practicing in Illinois with 35 years of experience supporting people through major life challenges and transitions. She approaches therapy as a process of transformation toward greater wholeness, peace, and happiness, and she combines careful assessment with a collaborative plan to help clients build insight and practical coping skills.

She listens with full attention and offers compassion, empathy, and care in a supportive therapeutic relationship where a client’s integrity and personal values are honored. Whether addressing depression, grief, relationship concerns, LGBTQ issues, or questions of faith and spirituality, she helps clients explore healing for body, mind, and spirit and works to reinforce and expand their natural support systems.

With specialized education in religion, spirituality, and psychology, she helps clients integrate spiritual resources alongside psychological approaches when that integration fits a person’s beliefs and goals. She places particular emphasis on repairing and strengthening connections - with family, friends, and other supports - because healing often unfolds in relationship.

She meets people where they are without judgment, provides a thoughtful assessment, and collaborates on a tailored plan to increase awareness, resilience, and meaningful change. LCPC indicates her state credential as a Licensed Clinical Professional Counselor, a credential to provide mental health therapy in Illinois.

Therapeutic Approaches and Online Care

Dr. Dier-Zimmermann draws on Acceptance and Commitment Therapy (ACT) to help clients clarify their values and take meaningful action even when difficult thoughts or feelings are present - this approach is often useful for anxiety, stress, and persistent mood concerns. She also uses Attachment-Based Therapy to explore patterns in relationships and to strengthen emotional bonds and security, which can help with intimacy issues, family dynamics, and grief. In addition, her client-centered orientation places the person and their lived experience at the heart of therapy, emphasizing empathic listening and collaboration to support self-directed growth.

Finding the right approach is part of the therapeutic process, and she works collaboratively with each person to identify which methods fit their needs, goals, and preferences. Together they review what is helping and adjust the plan as progress unfolds.

Online therapy with Dr. Dier-Zimmermann is available by video call, phone, live chat, or text-based messaging, offering flexibility for different schedules and comfort levels. These options make it easier to access consistent care from wherever the client is, support continuity during life changes, and accommodate preferences for more immediate or ongoing communication with a licensed professional.
