Dear Simone, Thank you for your personable and compassionate approach throughout my ADHD assessment and diagnosis. This has been such a significant and sensitive chapter in my life, and your patience, understanding, and ability to hold space made it feel safe for me to share life experiences that, at times, have felt overwhelming and even crippling. Because of the way you guided the process, I now feel more grounded and better equipped to move forward with my goals—both personally and professionally. I’m truly grateful for your support.
I’ve been singing Simone’s praises ever since. She was incredibly patient with me, even when I found it hard to explain what I’d been struggling with for years. For the first time, I felt truly heard and understood.
From the moment I met Simone, I felt completely at ease. Her calm and understanding approach made it easy for me to open up — something I usually find really difficult. It was like my anxiety just melted away
Getting diagnosed with ADHD later in life was a huge moment for me. Suddenly, so many things made sense! The challenges, the patterns, the way I’ve always felt different. I was guided through the process with so much understanding. I only wish I’d done it sooner!
