Sarah Richmiller, QMHP

Throughout life we are faced with obstacles, decisions, and hardships that we often least expect.

Sarah’s ideal clients are individuals who have experienced trauma including domestic, sexual, physical, and verbal abuse, as well as traumatic loss, PTSD, early childhood trauma, abandonment, addiction, anxiety, and depression.

Each life event leads us to becoming the person we are and having the life we have and sometimes that life isn’t the life we always longed for. Sarah’s approach in therapy helps lead to deep self-reflection, self-awareness and understanding of who we are as individuals.

She believes that once we understand who we are and where we come from, we can start healing and growing toward the positive life we have always deserved.

She has previously worked with children, teens, and adults in trauma-based settings and implemented healthy coping skills within her therapy approach. Sarah uses a humanistic and person-centered approach because each person is so intricately unique that they deserve to be worked with in a way that best fits their needs. She incorporates mindfulness-based techniques to help individuals connect their mind, body, and spirit to become present and connected with themselves at a deeper level.

She earned her bachelor’s degree in Clinical Counseling as well as her master’s degree in Clinical Mental Health Counseling from the University of Illinois at Springfield. She is a member of the American Counseling Association and is dedicated to growing, learning, and implementing new approaches that best benefit her clients.
