Autism and ADHD Assessments for Adults in Washington State
Maybe you’ve been trying to figure out whether what you’re noticing is ADHD, Autism, both, or something else entirely.
You might relate strongly to both but worry that they somehow contradict each other. Maybe previous providers focused on anxiety, trauma, or depression without considering the fuller picture. Or maybe you’ve researched this for years and still feel like you need to solve the entire diagnostic puzzle before you’re allowed to ask for an assessment.
You don’t.
I provide comprehensive, neurodiversity-affirming Autism and ADHD assessments for adults throughout Washington State. Every assessment considers both ADHD and Autism, along with sensory differences, anxiety, trauma, masking, burnout, and other experiences that may overlap or affect how things show up.
The goal is not to squeeze you into whichever diagnostic box you selected when scheduling. It is to understand the whole picture and figure out what actually fits.

You do not have to decide whether you need an “ADHD assessment” or an “Autism assessment” before reaching out. We’ll start with what you’ve been noticing and determine the most useful way to explore it together.
When you’re not sure what fits
People rarely arrive with their experiences already sorted into neat diagnostic categories. You might suspect ADHD, Autism, both, or neither. You may simply know that the explanations you have received so far do not fully account for how you experience everyday life.
ADHD and Autism can share features with each other and with anxiety, trauma, depression, sensory differences, chronic stress, and burnout. Similar experiences can also happen for very different reasons. Difficulty following a routine, for example, does not automatically tell us whether the issue involves attention, executive functioning, sensory needs, overwhelm, demand, or something else.
That is why the assessment does not begin with the assumption that you have ADHD, Autism, or both. We look at how your experiences developed, how they affect your life, what may be interacting, and which explanation is best supported by the full picture.
This assessment may be a good fit if
You are wondering whether ADHD, Autism, both, or another explanation may fit your experiences.
You were previously assessed for one condition but feel like something was missed.
Anxiety, trauma, depression, or burnout explain part of your experience but not all of it.
You have spent years masking, compensating, or appearing more okay than you actually felt.
Your strengths or achievements have made it harder for other people to recognize how much effort everyday life requires.
You want an assessment that considers your experiences in context rather than relying on stereotypes or a checklist alone.
You want clearer language for understanding your needs, communicating with providers, or requesting appropriate support.
You do not need to match every item on this list. Most people arrive with a collection of patterns, questions, half-finished theories, and internet research. We sort through it together.
What the assessment looks at
The assessment is designed to understand how your brain works across different parts of your life, not just whether you can check enough boxes on a questionnaire.
Depending on your experiences and the questions you bring in, we may explore:
attention, motivation, and executive functioning
routines, transitions, flexibility, and responses to change
communication and social experiences
sensory processing and regulation
interests, focus patterns, and sources of energy
masking, people-pleasing, and other ways you have learned to adapt
emotional regulation, overwhelm, shutdown, and burnout
childhood experiences and lifelong patterns
anxiety, trauma, mood, health, environment, and other factors that may affect functioning
Structured interviews and assessment tools provide useful information, but they are only part of the picture. Your history, context, coping strategies, internal experiences, and the effort required to keep things functioning all matter too.
How the assessment process works
1. Free consultation
We’ll talk briefly about what you have been noticing, what you hope to understand, and whether this assessment seems like the right fit. You do not need to arrive with a polished explanation or a perfectly organized developmental history.
2. Intake and questionnaires
The intake gives us time to explore your history, current experiences, strengths, challenges, and the questions bringing you to assessment. You will also complete questionnaires selected based on what we are exploring.
Input from a partner, family member, therapist, or another person who knows you well may be included when helpful and available, but it is not automatically required.
3. Comprehensive evaluation
We’ll use structured interviews, clinical assessment tools, and open conversation to look at ADHD, Autism, sensory processing, masking, executive functioning, and other experiences that may be relevant.
This is not a performance. You can move, stim, use notes, take breaks, ask for clarification, or communicate in whatever ways help you participate more comfortably.
4. Review and written report
I’ll integrate the information gathered throughout the assessment and prepare a comprehensive written report. Your report will explain the findings in clear language and include strengths, support needs, sensory information, and personalized recommendations.
Reports are typically completed within 3–4 weeks of the intake session.
5. Feedback session
We’ll review the results together, talk through what they mean, and make space for your questions. The goal is for you to leave with information you can actually understand and use, not a document full of unexplained clinical jargon.
What you will receive
Your assessment includes:
clear feedback about the findings
a comprehensive written report
diagnostic information when supported by the assessment
an explanation of your strengths and support needs
personalized recommendations based on your actual life
language you can use when communicating with providers, employers, schools, or other support systems
The report is meant to be useful after the assessment is over. You should not need a clinical dictionary and three hours of uninterrupted concentration just to understand what it says.
What the report may be used for
Depending on your results and the requirements of the organization reviewing it, your report may support:
personal understanding and identity exploration
treatment planning and care coordination
conversations with medication providers
requests for workplace or educational accommodations
communication with other healthcare professionals
A diagnosis does not guarantee medication, accommodations, insurance reimbursement, or acceptance by a particular organization. Each provider, employer, school, and insurer sets its own documentation requirements.
These assessments cannot be used to qualify for SSI or other government disability benefits. If you need documentation specifically for a state disability determination, you will need an evaluation from a psychologist or another provider whose assessment meets that program’s requirements.
Common questions
Do I need to know whether it is ADHD or Autism before scheduling?
No. You can come in knowing exactly what you want assessed, strongly suspecting both, or mostly just curious. Clarifying the question is part of the process.
Can someone be diagnosed with both ADHD and Autism?
Yes. ADHD and Autism can occur together. The assessment does not assume that you have either or both, but it considers each possibility and follows the information gathered throughout the evaluation.
Do I need childhood records or someone who knew me as a child?
Not necessarily. Childhood records or input from someone who knew you earlier in life can sometimes be helpful, but many adults do not have access to either. We will talk about what information is available and how to approach any gaps.
Is this assessment appropriate for high-masking adults?
Yes. The assessment considers internal experiences, masking, compensation, sensory needs, and the effort required to manage everyday life. Appearing capable from the outside does not tell us how much work is happening behind the scenes.
Can I pursue an assessment if I already self-identify as Autistic or ADHD?
Yes. Self-identification is treated as meaningful information, not something you need to defend. The assessment still remains open to whatever explanation is best supported by the full picture.
Do you accept insurance?
I am an out-of-network provider and do not bill insurance directly. Superbills are available for possible reimbursement, depending on your plan. The assessment fee is $2,500, and a split-payment option is available.
Ready to get started?
You do not need to finish researching, organize your entire life into a timeline, or become completely certain before reaching out. We can start with what you know now.
