| The Healthcare Professional Who's Always on Edge | You've spent years in a demanding field where attention to detail matters, but lately you're forgetting appointments, losing track of patient notes, and feeling like you're barely keeping up. You know you can't "push through" this much longer. |
| The Mid-Career Leader Struggling to Delegate | You've built a strong reputation and climbed the ranks, but the bigger your team gets, the harder it is to stay organized.

When your child was recently diagnosed with ADHD, you started recognizing your own lifelong struggles with impulsivity, emotional reactivity, and chronic overwhelm. |
| The Tech Worker Who Can't Focus Anymore | You've been in software development for years, but lately the distractions are winning. You switch between tasks constantly, miss stand-up meetings, and lose hours to hyperfocus on the wrong priorities. You're starting to wonder if this is burnout or something more. |
| The Small Business Owner Who's Drowning in Details | You love your work, and you're proud of what you've built, but the administrative side feels impossible. Invoices pile up, emails go unanswered, and you're constantly putting out fires. You need a diagnosis that helps you understand what's been holding you back. |
