What to Expect After the ADHD Assessment

Undiagnosed ADHD can disrupt your life, without you knowing. Once you get a comprehensive assessment with ADHD Certify, you can:

Get Clarity on Symptoms

Identify major symptoms like hyperactivity and understand how ADHD causes them. This can help you reach validation and comfort in yourself as all these symptoms are not personal shortcomings but are rooted in a medical condition.

Improve Self-Understanding

Know that it’s not your fault. It’s ADHD that’s affecting your daily life. This can be empowering as you now have a clear view of where you are and can plan your day-to-day routine for better management and, eventually, increased self-esteem.

Access Tailored Treatment

With a comprehensive assessment, you’re on the path to a tailored ADHD treatment plan. This bespoke approach will ultimately help you manage your ADHD, resulting in more focus and reduced stress. And an overall better experience in life.

Timely ADHD Assessments, Made Easy

What Our Clients Say About Their Journey

“There’s nothing to be afraid of, I’m so glad I got my ADHD diagnosis”

Hi, I’m Samantha Baines
Actress – Presenter – Author – Comedian – Mum

ADHD Certify Patient – Samantha Baines
For many adults, the journey to understanding ADHD starts with a series of unanswered questions. Samantha Baines, an actress, presenter, author, comedian, and mum, found herself struggling with time blindness and an overactive mind made it difficult to focus, especially under stress.
After years of navigating these challenges, Samantha decided it was time to seek answers.

The Diagnosis Process: A Smooth and Supportive Experience
Taking the first step toward an ADHD assessment can feel overwhelming, but Samantha quickly realised there was nothing to be afraid of.
“I’m so glad I got my ADHD diagnosis,” she says. The process with ADHD Certify was straightforward and reassuring. The ADHD clinician was clear and calm throughout, making the whole experience feel welcoming and supportive.
The structured approach made it easier for her to reflect on her experiences, and the comprehensive report gave her a detailed understanding of her ADHD diagnosis

Life After Diagnosis: A Transformative Change
Receiving an ADHD diagnosis was a turning point for Samantha.
Now officially diagnosed with ADHD Combined Type, Samantha feels empowered. She has a clearer understanding of herself, which helps her navigate life and work more effectively. “It gives me more information about how I can come up with strategies that will help me in my job and in my life.”

Breaking the Stigma: What Everyone Should Know About ADHD
When asked what she wishes more people understood about ADHD, Samantha highlights the importance of awareness and education.
There are different types of ADHD, and many people mask their symptoms to fit in. A diagnosis isn’t just a label—it provides valuable information and strategies that can truly improve quality of life.
By sharing her story, Samantha hopes to encourage others who might be feeling lost or overwhelmed to take that first step toward understanding their own minds.

Very very happy with these guys, Rebecca Wilson senior clinician is outstanding and then I dealt with Annisah to discuss medication, a very emotional and informative chat and for the first time in 53 years I realised what is wrong with me, could not recommend more highly, thank you for helping me to change my life for the better, excited about the future for the first time ever

We would highly recommend ADHD Certify. All communications and interactions with them have been positive and we were able to arrange and complete my son’s ADHD assessment within a week. The practitioner that completed his assessment (Roina Moussirou) was brilliant with a very calm and helpful style. My son often struggles to engage with strangers however he felt at ease talking to Roina about his life. As a parent I learnt more about my child and his daily struggles and found the assessment to be very thorough. After the assessment Roina arranged for a follow up session a few days afterwards where my son’s diagnosis was delivered sensitively. I have recieved extensive information and support through links and documents following the diagnosis which will be helpful for support moving forward. Once again, I would highly recommend, very impressed with the service. Thank you

I had an excellent experience during my ADHD screening with Toni Henderson. The interview was thorough and in depth, with specific, thoughtful questions and plenty of time to give detailed answers and discuss my experiences without feeling rushed. Toni was incredibly understanding and accommodating of my travel circumstances on the day, which I really appreciated. Her wealth of knowledge and experience was evident throughout, yet the conversation felt natural and flowed easily. She made me feel comfortable, listened to and understood. I’m very pleased to have been seen by someone so experienced and compassionate, and I would highly recommend her.

I had my assessment yesterday with Kerri. I get super nervous and anxious meeting new people, especially in these kind of circumstances, but Kerri was incredible, so kind and patient and I felt comfortable so quickly. Kerri was very clear throughout, and gave me ample time to think and speak. Very glad I chose ADHD Certify, and extra glad I chose Kerri. Thank you 🖤
