 What our Clients Say About Us 

" [My psychologist] is incredibly easy to talk to. I reached a point where I knew I needed to find better coping strategies. I'm from a family that's really against labels, so I thought I'd struggle to discuss, but it was actually easy to open up. 
I'd highly recommend. I feel already I'm making positive changes and understanding myself better and where my challenges come from."

Do You Feel Like You're Between Two Worlds?

Many adults discover they're not "just ADHD" or "just autistic" - but both

You Might Relate If:

  • Sometimes you're hyperactive, sometimes you shut down completely

  • Social situations drain you, but you crave connection

  • You need routine AND novelty to function
    Sensory overwhelm meets executive dysfunction

  • Previous assessments only captured part of your experience

  • You've been masking so long, you're not sure who you really are

You Deserve an Assessment That:

Brings clarity to complexity - not just one condition

Understands masking - especially in women & gender diverse adults

Takes time to understand you - up to 5.5 hours across multiple sessions

Identifies strengths and challenges - not just deficits

Supports you after - diagnosis is just the beginning

The AuDHD Assessment Difference

Specialist Expertise

We specialise in complex, overlapping presentations, including intersectional identities, co-occurring mental and physical health conditions, and experiences of trauma. Not a one-size-fits-all approach.

Time & Depth

Up to 15 hours of clinical time. We don't rush – your unique experiences deserve attention and understanding.

Compassionate Care

Developed by late-diagnosed ND professionals and informed by the dynamic neurodivergent community.

Comprehensive ADHD & Autism screening

Up to 4.5 hours assessment time (split sessions)

Already Have a Diagnosis of ADHD or Autism?

Many adults receive one diagnosis, but something still doesn't feel complete. You know there's more to your story.

We offer holistic assessments that fit the pieces together - creating a comprehensive understanding of your neurodivergence, not just another disjointed diagnosis that fails to capture your whole experience.

Explores how ADHD and autism traits interact and overlap in your life

Creates a unified narrative that finally makes sense

Provides clarity on the interaction between neurodivergence and related co-occurring mental health, physical health and trauma-related difficulties

Offers integrated strategies that work for your complete profile

Why it's Worth the Investment

Unlike quick conveyor belt assessment services, we dedicate significant time to understanding your unique presentation and experiences. For AuDHD assessments specifically, we explore how ADHD and autism traits interact and overlap in your life. This depth leads to more accurate diagnosis, better self-understanding, and truly personalised support that addresses your complete neurodivergent profile.

As practioner with lived experience of ADHD, Autism and AuDHD,

we don't just understand neurodivergence -

we understand the reality of living with and experiencing the world, ourselves and others through our neurodivergent minds

" I know all about the frustration
of long waiting lists and the limitations of quick, impersonal private assessments and support.

I know we deserve better.
That's why I've developed a service that offers more than a 'yes' or 'no' diagnosis. We tailor assessments, therapy and support to the unique individuals we serve."
