While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more
The ADHD Expert provides specialist ADHD therapy, coaching and brain health support for adults, parents and families who want to understand ADHD at a deeper level.
Founded by Sean McNicholas, The ADHD Expert combines professional therapeutic experience, advanced study in ADHD, trauma, brain health and nervous system regulation, and lived experience of ADHD. The approach goes beyond simply managing symptoms and focuses on helping people understand why they think, feel and behave the way they do.
ADHD is not just about attention, focus or concentration. It can also affect emotional regulation, motivation, executive function, stress tolerance, relationships, sleep, confidence, self-worth and daily functioning. Many people with ADHD also experience anxiety, overwhelm, burnout, shame, masking, trauma or long-term patterns of feeling different, misunderstood or not good enough.
The ADHD Expert supports clients through a warm, compassionate and practical approach that looks at the whole person — the brain, nervous system, emotional wellbeing, life experiences, behaviours and environment.
Services may include ADHD therapy, coaching, brain health support, functional neurology, brain mapping, emotional regulation work, trauma-informed support, parenting guidance and strategies to help improve focus, resilience, confidence and daily functioning.
The aim is to help clients move from confusion, frustration and self-blame towards greater understanding, regulation, healing and hope. So you can live a more calm and balanced life.
The ADHD Expert is for people who want more than generic ADHD advice. It is to spend time with an expert who has real life experience and phenomenal knowledge on the ADHD brain, so you can understand why we think, feel and behave the way we do, and want to do something about improving their life. It is for those who want to better understand their brain, feel more supported, and create meaningful change in their life, relationships, family or work.

I have been looking for someone like Sean for years. Someone who can answer every question about ADHD and beyond. I have been seeing him every week for the last 6 months and my transformation is beyond belief.
My wife has a new 'considerate' husband, my kids have a new 'present' dad. I am enjoying work again and all of my bad habits have gone away.
I highly recommend Sean to anyone who is looking for change.
