An education company for work that actually matters
Garentia was founded in 2023 on a single, unusual idea: that the capacity to support someone with ADHD is not a rare gift bestowed on a few specialists. It is a combination of natural traits already present in millions of ordinary people, most of whom have no idea they carry it.
We exist to help those people recognize what they carry and make it real. Everything we teach is built on the 5-trait framework Linda developed over 14 years of hands-on practice, then wrapped in the training, credentials, and ongoing support it takes to enter a field that desperately needs them.
Today, our coaches serve clients across the world, meeting people with ADHD exactly where they are, with an affirming, evidence-based approach rather than "try harder" advice, using the methodology our founder spent her career refining.
To reach the people who carry the rare mix of traits ADHD clients need most, equip them to do this work professionally, so no one who needs affirming, credible help has to go without it.
The 5 traits this work is built around
These are the traits our founder identified, after 14 years of clinical observation, as the combination that consistently produces effective ADHD coaches. They cannot be taught. Everything else can.
If you saw yourself in those five, people across the world need exactly what you carry. The certification is how you turn it into a profession.

Linda spent the first two decades of her career as an accountant. She was good at it. Precise, reliable, thorough. But she carried a quiet restlessness she couldn't name: the feeling that she'd been built for something she hadn't yet found.
That something arrived when she was 48. Her young nephew was diagnosed with ADHD. While the rest of the family pulled back, uncertain and afraid of saying the wrong thing, Linda moved closer. She sat with him. She followed his lead. She met him exactly where he was. And he responded in ways no one expected.
For the first time in her adult life, the restlessness went quiet.
Linda left accounting. She invested almost everything she and her husband had saved into years of intensive study in ADHD, executive function, behavioral frameworks, and evidence-based coaching. She earned advanced credentials from five international accreditation bodies. Then she built a practice from nothing, growing it into one of the most respected in her region, eventually serving over 250 clients across 14+ years.
It was through that hands-on work that she identified the five-trait pattern that defines who naturally connects with people with ADHD. She built the certification program her coaches now use to channel those traits into professional practice. She submitted the program back to the same five accreditation bodies that certified her own credentials. Every one of them accepted it.
Linda still sees clients personally. The one-on-one work is where the calling started, and she has no intention of leaving it behind. But the bulk of her energy now goes into the program, the methodology, and the growing community of certified ADHD coaches carrying her work to people around the world.

Hear from the people already doing this work

"I was sure I needed a psychology degree. I didn't."
I almost didn't enroll because I have no clinical background at all. But the program teaches the brain and the coaching skills from the ground up, in plain language. Within a few weeks I was helping clients build routines that actually stuck. You do not need letters after your name to do this well.

"It gave my coaching a real specialty."
I'd coached for years on general productivity, but ADHD clients kept finding me and I was working off guesswork. This gave me the actual mechanisms: executive function, motivation, why the usual advice backfires. Now I know what I'm doing, my clients trust me more, and my referrals have gone up.

"I started it for my son. I kept going for everyone else's."
I signed up to understand my own ADHD child and stop the nightly homework battles. It worked at home faster than I expected. Then other parents at school started asking how I did it, and I realized I could do this for a living. I now coach families through the exact chaos we used to live in.

"I did the math, then I stopped hesitating."
I sat on this for weeks. Then I worked out that just a few clients a month at normal coaching rates would cover the cost many times over. The risk was basically zero. I enrolled that night and had my first paying client within two months.
