Courtney Reimmuth, RN, is the founder of Grey Matters Brain Training Studio — but before she built a studio, she was a mom searching for answers. When her son, Grey, was diagnosed with apraxia and ADHD, Courtney began pursuing real solutions that offered more than explanations. That journey led her to neurofeedback and inspired her to create the kind of place she wished had existed for her own family.
With more than 20 years of experience spanning nursing, psychology, nutrition, business management, and digital marketing, Courtney brings a unique blend of clinical understanding and heartfelt compassion to Grey Matters. She understands both the science and the emotional weight families carry when they are searching for answers, and she has built the studio to be a place where children, adults, and parents feel supported, understood, and no longer alone.
