About Dr. Mary Ann Dier-Zimmermann

Dr. Mary Ann Dier-Zimmermann is a Licensed Clinical Professional Counselor (LCPC) in the State of Illinois with over 30 years of experience. She frames healing as a personal journey toward greater wholeness, peace, and happiness, guiding each person through thoughtful, individualized care.

She listens with full attention and brings compassion, empathy, and genuine care to the therapeutic relationship. In that setting she emphasizes respect for personal integrity and works collaboratively to address concerns such as depression, grief, relationship difficulties, LGBTQ+ issues, and questions involving faith, spirituality, or religious life. Her approach seeks to support healing of body, mind, and spirit while honoring each person’s beliefs and life context.

Recognizing that recovery and growth often happen in connection with others, she also focuses on repairing and strengthening relationships with family, friends, and broader support networks. Clients receive a clear assessment and a tailored plan, and she partners with them to expand awareness, build supports, and pursue meaningful change.

With specialized education in religion, spirituality, and psychology, Dr. Dier-Zimmermann helps integrate these dimensions into the therapeutic work when that integration is important to the individual. She meets people where they are, without judgment, and honors gender orientation, life circumstances, and personal beliefs as pathways toward transformation.
