“We’re not just relaxing the mind—we’re rebuilding its rhythm.”
— Jen Beyst Co-Founder, CFDI
You know what it means to perform under pressure — managing teams, clients, and constant demands on your time and attention. But even the most skilled professionals can experience mental fatigue, emotional dysregulation, or a sense of cognitive “drag.”
At Brain Builders, we help you optimize your brain and nervous system function so you can operate with greater clarity, adaptability, and balance — in work and in life.
Every professional’s brain works differently. Our CFDI Cognitive Function Assessment uses 12 scientifically validated subtests (via Creyos) to evaluate your attention, memory, and executive systems.
Your report reveals where you’re strongest, where your brain may be under strain, and provides targeted recommendations for improvement. (If you continue with a CFDT program, a progress assessment is included at no additional cost.)
Based on your assessment, we identify which CFDI Therapeutic Tones are most effective for your unique neural rhythm.
Our Cognitive Function Development Therapy (CFDT) program is a 12-week, personalized development experience that integrates cognitive, emotional, and physiological transformation.
You’ll work 1:1 with a trained CFDT practitioner, either in person or remotely, to strengthen your brain’s adaptive capacities.
Ages: 6 and up — specialized pathways for adults and professionals
Cognitive Function Development Therapy is not “brain training.”
It’s a dynamic, human-centered approach that engages the brain’s natural oscillations — helping you build neural flexibility and optimize regulation from the inside out.
When your brain’s networks are balanced and synchronized, performance follows effortlessly.
