Your Brain, Our Expertise


Virtual & In-Person Options
Compassionate, Comprehensive Care for Every Stage of Life
We offer flexible access to care through both in-person appointments and secure telehealth services, allowing clients to choose the setting that best fits their comfort, location, and schedule. Virtual sessions are ideal for consultations, psychological assessment components, and psychotherapy, providing an accessible option for those across PSYPACT participating states.
For services that require hands-on clinical technology—such as qEEG brain mapping and neurofeedback training—we provide in-office appointments at our Chicago location. These in-person services ensure precise data collection, professional monitoring, and optimal treatment outcomes. Whether online or onsite, clients receive the same attentive, individualized support from our team.
