Autism & ADHD Assessments
Sometimes, life makes more sense when you finally have the words to describe your experience. I offer gentle, supportive assessments for adults who may be wondering if Autism or ADHD plays a role in how they think, feel, and move through the world.
My goal is to create a safe, judgment-free space where you can explore your questions and gain clarity. Together, we’ll look not just at challenges, but also at your strengths, so you can better understand yourself and feel more confident moving forward.
Getting an assessment isn’t about labeling—it’s about self-discovery, self-acceptance, and finding the right tools to support the life you want to live.
If you’ve been searching for answers, you don’t have to do it alone. I’m here to help.
No two people experience autism in the same way. Our identities—like race, gender, culture, and sexuality—shape how we experience the world and how others see us and how we see ourselves. Because of this, some people are often missed or misunderstood in the assessment process.
Taking an intersectional approach means looking at the whole person, not just a checklist of traits. It helps ensure your unique story is heard, respected, and understood. This way, the assessment is more accurate, more compassionate, and more reflective of who you truly are.
Too often, certain groups—such as women, people of color, and LGBTQ+ individuals—are overlooked or misdiagnosed because their experiences don’t match outdated stereotypes. By honoring the whole person and considering the many identities they hold, assessments become more accurate, compassionate, and meaningful.
An intersectional approach helps ensure that each person’s unique story is heard and validated, paving the way for a clearer understanding of their strengths and needs.
Each evaluation includes multiple sessions, including a detailed diagnostic interview, standardized measures, and cognitive testing. When appropriate, input from trusted people is welcome. Feel free to bring notes, a pet, binders, or old report cards. My role is to help you explore and understand your experience, not to label, but to support your self-awareness and remove barriers.
The full cost of the assessment and report is $800. Payment plans are optional.
The Assessment Process:
Step 1: Consultation Call
This is a brief, 15-minute consultation telehealth call to answer any questions and to allow you to make an informed decision on moving forward. Please feel free to bring any self-assessments and information gathered to this meeting.
If you decide to move forward, we will schedule the assessment.
Step 2: Diagnostic Interview
The diagnostic interview includes an in-depth interview process (MIGDAS-2) as well as the use of several evidence-based self-administered questionnaires (Browns ADD, RAADS-R, CAT-Q, Monotropism Questionnaire). Following the initial interview, a second session will be scheduled where diagnosis, additional feedback, a comprehensive report, and a list of resources/referrals will be provided. Accommodation letters are available on request and may be used for most medical and academic accommodations. This session is a 3-hour session or broken up into two 90-minute sessions.
Step 3: Results Meeting
The final session is a results meeting, where we discuss your assessment findings in detail. We provide personalized referrals and recommendations for next steps, helping you move forward with a clear and informed understanding of yourself.
Within a few weeks of this meeting, you can expect to receive a highly detailed report of your testing results, along with specific, tailored recommendations to your unique needs.
Heather Sexton, PhD., LPCC-S, CST, IRT
Hi, I’m Dr. Heather. Since my own late Autism diagnosis, I am passionate about offering neurodivergent-affirming assessments. I have personally experienced how individuals are overlooked in traditional diagnostic settings, particularly for those who have spent years adapting to systems that were never designed with them in mind. If you’re here exploring the possibility of a diagnosis as an adult, you are not alone, and you’re not too late. I specialize in adult diagnostic assessments for Autism and ADHD. My assessment process is collaborative and affirming. I encourage individuals who have done their own research, explored self-diagnosis, or found resonance through social media or peer communities to bring what they have learned about themselves. This is a joint process, and your voice belongs at the center.

A psychological evaluation is typically an extensive process - it is a time and sometimes cost-intensive process of assessing cognitive, emotional, social, and behavioral functioning. Psychological evaluation can encompass many types of information gathering, including many types of psychological testing (sometimes called a battery of testing), and is conducted by a Licensed Clinical Psychologist. This type of assessment can be helpful for looking at a wide range of potential explanations for behavioral, social, emotional, and neuro-differences, and is often valuable in evaluating developmental and neuro-cognitive differences, including evaluation for educational needs such as specific learning differences and disabilities. An autism assessment includes many forms of information gathering - social and developmental history, self-report inventories/questionnaires, and interview session(s) using neurodiversity affirming, evidence-based diagnostic protocol - it does not include neuropsychological testing. My evaluations are intentionally limited in their scope, as this is an area of specialization and expertise - Diagnostic Evaluations for Autism are for the sole purpose of evaluating and identifying/diagnosing Autism. This form of assessment often does not meet the requirements for disability approval.

The total cost for the Autism Assessment is $800. At this time, I am only in network with limited insurance plans at the time (Aetna, Medical Mutual, Peak, and United), but self-pay is an option as well as payment plans. If you choose to utilize insurance, there is a possibility that insurance MAY NOT cover.
