Gretchen attended James Madison University for her undergraduate studies and graduate school at Virginia Commonwealth University and Boston University. She has practiced for three years in various settings, including residential facilities for children, acute care facilities, and private practice, where she successfully supported clients with neurodiversity in improving executive function, emotional regulation, and interpersonal relationships. Recognizing the complexities of neurodiversity beyond traditional clinical frameworks, Gretchen collaborates with medical professionals, educators, and families to create inclusive environments that foster success for individuals with neurodivergent traits.

Clients can expect to gain a deeper understanding of their thought patterns and uncover the underlying meanings behind their reactions. Through a collaborative and reflective process, they’ll develop greater self-awareness, challenge limiting beliefs, and gain clarity in their personal growth journey. This approach empowers clients to make more informed, intentional choices in their lives.

Gretchen takes a direct yet supportive approach, evident from the very first session. She integrates psychoeducation, somatic techniques to enhance body awareness, and strategic reframing to help clients uncover core beliefs that may be contributing to their challenges.
