Gold-Standard ADHD assessments for adults (18+) in Epsom, Wimbledon, and online.
Not just a diagnosis, but a nuanced roadmap of how your brain is wired.
The ADHD PARADOX
High achievers with ADHD are brilliantly capable, yet the basics of life can be totally overwhelming.
If your performance doesn’t quite reflect what you know your potential is, you may want to take a closer look at ADHD.
Adults with ADHD live with a type of tension that is hard to explain.
When the stakes are high or the interest is there, you’ll outperform everyone in the room. But if a task is "boring," your brain simply goes offline, no matter how hard you try.
It is difficult to understand how the same person can be so competent and capable in some areas, and fail to show up in others.
Whilst the ADHD brain can be absolutely brilliant, left unmanaged, it can also wreak havoc on your life and your self-esteem.
A comprehensive assessment is the first step in understanding how your brain works. Our goal for all of our clients is to empower you to find the tools and resources you need to allow your performance to match your true potential
How does it work?
Keeping assessments simple and accessible
We know how overwhelming it is to look for an ADHD assessment. We have designed our process to be as clear and supportive as possible, so you can follow one simple step at a time.
Step 1
Book a Discovery Call
This is a 20 minute chat via Zoom with Dianne Everitt to look at your history and current challenges. We’ll determine if an ADHD assessment is the right path for you, or if another direction would serve you better. If you have been referred by another professional, you can skip this step.
Step 2
The comprehensive assessment
Once we’ve confirmed the pathway, we’ll guide you through the initial paperwork and then meet for a 3 hour clinical interview. This is a deep-dive into your story, your struggles, and your unique strengths. The appointment can be in person or online.
Step 3
Your results and roadmap
Three to four weeks after your assessment, we’ll meet for a feedback session. You’ll receive a comprehensive report that is NICE-compliant and widely accepted. Our reports provide more than a diagnosis. We give you a tailored roadmap with clear steps to take.
What a Gold-Standard Assessment looks like
If we were looking for a top-quality assessment for one of our family members, we would look for these eight clinical essentials:
The expertise rule
With over 10 years of experience, you are seen as an expert, rather than a generalist.
a 3-hour deep dive
Anything less than this is not enough to reach a thorough, evidence based diagnosis.
A Holistic View
We look beyond ADHD to see the whole picture of your mental health, ensuring nothing else being missed.
A team approach
Although a team approach is not required for ADHD assessments, we like to have regular peer reviews within our team, to increase the rigor of our results.
Evidence based tools
We use "Gold-Standard" validated questionnaires to ensure our findings are backed by data
NICE-guideline compliant
This is the "North Star" for UK healthcare, ensuring your report meets the standards of the NHS.
Multiple Perspectives
We don’t just rely on your memory; where possible, we collect information from other sources to see how you function in different environments.
Offers a feedback session
We don’t just email you a report. We sit down with you to explain the "why" behind your results and help you plan your next steps as part of your roadmap.
We are proud to say
we meet all of the above criteria
In all of our assessments, we follow the guidelines set out by the National Institute for Health and Care Excellence (NICE). Our Gold-Standard assessments ADHD assessments in Wimbledon and Epsom are rigorous, regulated, ethical, and widely accepted by the NHS and across the UK.

We have a team dedicated to assessments, and we like to keep things as efficient as possible. This allows us to have very short waitlists, and we can usually get you booked in within a month of inquiry.
-
Our assessments follow NICE guidelines, the same standards used by the NHS. We cover all of the areas required by the NHS, and check their boxes. However, each NHS location has different processes, and some trusts are not accepting private diagnoses at all due to pressure on their services. It depends entirely on your local service. Our advice is that you call your GP before you start a private asssessment, and ask them if they accept shared care for ADHD. If they do, ask them if they have any specific terms, as this will help us make sure we signpost you to the best prescriber if you want to access medication. If they do not accept shared care, your GP will not manage your medication unless you go for an assessment through the NHS.
-
If you are not diagnosed with ADHD, we spend our time in the assessment understanding your challenges and strengths in great detail. We will give you a reason that better explains your symptoms if it is not ADHD, and talk to you about what you can do to find the appropriate support.
-
We cover the diagnostic process in detail. If you are diagnosed with ADHD, there are a number of treatment options available as a. next step. We have close partners we work with for post diagnostic intervention, who we will refer you to if you would like to explore your options.
-
It is not uncommon for adults to not have access to a parent for many reasons. Some choose not to have their parents involved in the process. In this instance, we will ask if you have access to a relative who knew you when you were young and can provide some information, or we will ask you to provide us with childhood information to the best of your ability. We can usually work with what we have, and know how to ask the right questions to gather the evidence we need to determine if ADHD is present or not. We will also ask someone who knows you well now to provide us with additional information, so that we are not only relying on your memory, as this can be challenging when ADHD is present.

It is very common that girls and high achievers with ADHD are top performers, both in school and in the workplace. This is because ADHD presents differently in girls and in high achievers, where intelligence and high masking strategies hide some of the underlying difficulties. Our team is skilled at taking a deeper dive into the inner experiences, and we don’t only rely on the external performance.
ADHD in high achievers doesn't look like the stereotype. It can look like a professional who presents brilliantly in a boardroom but can't file their tax return. A woman who has managed anxiety for years, never realising it was downstream of undiagnosed ADHD. Someone who only gets things done under the pressure of a looming deadline.
For women especially, ADHD is underdiagnosed because the distress goes inward rather than outward. It can look like a racing mind, perfectionism, emotional sensitivity, and an exhausting effort to appear effortlessly capable.
At Sage, we know how to look beneath the surface and find the hidden cost of ADHD in high achievers and women.
ADHD in High-achievers and women
For many adults, particularly women, ADHD goes undetected for decades. Not because it isn't there, but because they became exceptionally good at compensating for it.
High-achieving adults with ADHD often deliver, meet deadlines, and hold it together - at least on the surface. But what nobody sees is the hidden cost. Hours of paralysis before a "simple" task, relationships quietly suffering, cyclical burnout and the shame that follows.
Post-Diagnostic Support
Following a diagnosis of ADHD, you may want to work with ONE OF our psychologists
in London, Wimbledon, Epsom or online, who understands the nuances of ADHD well.
Getting a diagnosis of ADHD in adulthood is a big process and there is a lot to work through. It often comes with a mix of relief and grief.
The support process often involves strategies for your challenges and leveraging your strengths, and well as reshaping your self-esteem and building confidence.
If you would like support after a diagnosis, our practitioners are highly skilled in this area.
Unsure about whether to have an assessment?
We have put together an evidence-based ADHD screener for adults, that will tell you whether you are over the threshold for ADHD.
