I have worked in health care for over twenty years. In England, I trained and worked as a registered nurse and obtained a bachelor’s degree in psychology before moving to Canada and setting up my practice as a coach for adults with ADHD.

My Untapped Brilliance blog has been named a “Top ADHD Blog of 2015, 2016 and 2017” by Healthline, “Best of the Web Blog” by Psych Central and “Top 20 ADHD Blog Winner” by ADDerworld.

In addition, I was a writer for the health website VeryWell.com for two years as their ADHD Expert.

My book Untapped Brilliance has helped thousands of adults with ADHD.


The Untapped Brilliance Story

Way back in 2007, I was frustrated because I couldn’t find a straightforward, comprehensive book for adults (not children) with ADHD that I could refer my clients and blog readers to .

I wanted the book to be:

  • Easy to read
  • Be more than just a description of what Adult ADHD is
  • Focus on every aspect of Adult ADHD; not just one part. E.g. organizing or nutrition
  • Include ADHD-friendly strategies to stop challenges from being problems

When I couldn’t find the book I was looking for, I decided to write it!

Once I had made the decision to write a book, I knew exactly what the content was!

It would be the 11 steps of the Signature Coaching Program I created, and had been using for myself and with coaching clients and got such great results.

The 11 steps solve a problem I heard again and again.

‘I have so much potential, but I just can’t seem to achieve what I know I am capable of’.

I could see for myself how amazing each person was. However, their untamed ADHD symptoms were making it hard work just maintaining status quo; let alone any movements forward.

In two words, ‘Untapped Brilliance’ describes and positions this beautifully.

One reader said that of all the books on ADHD she had read, this one was the first with a positive title.

Since it was first published in 2008, Untapped Brilliance has helped 1000’s of people.

"Untapped Brilliance is a little gem of a self-coaching primer. In straight-forward language Jacqueline Sinfield proves practical advice and simple easy-to-follw techniques that will help adults challenged by AD(H)D to re-create their lives"

Can’t get past the first few pages of a book?

Adults with ADHD often drop a book after the first few pages because they get easily distracted. Sound familiar?

I wrote Untapped Brilliance with the ADHD reader in mind so that the content feels accessible and easily digestible.

The result? Readers tell me "Jacqui, this is the first book I have ever read cover to cover" all the time.

"I feel this is the first book that actually caters to the distracted mind! The paragraphs are short & concise, yet packed with wonderful ideas that are not only helpful but “do-able”. “Thank you, Jacqui, for speaking my language! Saturday 12:30- I open the book with a feeling of excitement that maybe, just maybe, my life will begin to change. As I read the forwards from others, my excitement builds. I turn to Chapter 1 and before I know it I’m on Chapter 5 (that doesn’t usually happen with me and self-help books. I am constantly re-reading as I get distracted and, when I get to the end of the page; realize I have no idea what I just read!). I actually finished Untapped Brilliance on Sunday!”"
