Dr. Marion Zahn is committed to helping her clients experience greater fulfillment within themselves and their relationships with others through individual, group, and couples therapy, as well as biofeedback and neurofeedback training.


“Therapy is a process that, for many people and under certain conditions, can be a transformative one.” –Marion Zahn, Ph.D.


Dr. Zahn holds a Ph.D. in Counseling Psychology from Texas A&M University (APA Accredited), where she has served as visiting assistant professor. In addition to coursework at Texas A&M, she completed an internship at Appalachian State University Counseling Center (APA Accredited), with an emphasis in mind-body wellness and mindfulness-based approaches to psychotherapy for the treatment of depression, anxiety, and past trauma. She has received additional training in biofeedback, neurofeedback, attachment in psychotherapy, multicultural counseling, and yoga for depression and anxiety. As a clinician, she tailors her therapeutic approach to her client’s particular concerns and needs, taking into account her client’s life circumstances, developmental stage, cultural influences, and the contexts in which her client exists. In her spare time, she enjoys practicing and teaching yoga and meditation, exploring diverse destinations and cultures, and sampling different cuisines.

Therapeutic Approach

Trained under the scientist-practitioner model, Dr. Zahn uses mindfulness/mind-body, emotion-focused, and cognitive-behavioral approaches as primary guides. She believes that therapy is a process that, for many people and under certain conditions, can be a transformative one. To help her clients activate their natural human tendencies toward growth, she focuses on building and maintaining a strong therapeutic relationship, where her clients can feel free to be with and explore their experiences with a sense of curiosity, compassion, openness, and acceptance.

In this exploratory process, Dr. Zahn can help you:

  • Work toward experiencing greater fulfillment in your life and relationships with others
  • Cultivate an increased sense of attunement with yourself and being with your present experiences
  • Develop your emotional intelligence and enhance your ability to tolerate and manage negative feelings and experiences

Biofeedback/EEG Biofeedback (Neurofeedback)/Quantitative Electroencephalography (QEEG Brain Mapping)

As an adjunct to counseling or as stand-alone training, Dr. Zahn offers biofeedback and neurofeedback services. QEEG brain mapping is also available to help guide the neurofeedback training process.



Biofeedback is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance. Precise instruments measure physiological activity such as brainwaves, heart function, breathing, muscle activity, and skin temperature. These instruments rapidly and accurately “feed back” information to the user. The presentation of this information — often in conjunction with changes in thinking, emotions, and behavior — supports desired physiological changes. Over time, these changes can endure without continued use of an instrument.”

Train Your Brain. Elevate Your Game.

Neurofeedback/Biofeedback training has been used to help cultivate peak performance by:

  • Athletes
  • Performers
  • Business Executives and Entrepreneurs
  • Students





Quantitative Electroencephalography (QEEG Brain Mapping)

QEEG measures brain wave activity. A sensor cap containing small electrodes is placed on the head to measure the brain’s electrical activity. This information is recorded and analyzed with FDA-registered software designed to create a brain map that is used to guide the neurofeedback training process.

At Wilcrest Counseling Services, Dr. Zahn uses the NeXus-32, a powerful, FDA-registered system for biofeedback, neurofeedback, and QEEG.
