Complete Privacy.

Adults seeking an autism evaluation in Arlington prioritize three things: expertise, privacy, and convenience. Your privacy matters – that’s why we do not work directly with insurance. As a private-pay practice, we ensure your privacy by only communicating directly with you. The results of your evaluation are not shared with your insurance company, and by extension, your employer. You may choose to share your evaluation with whomever you wish, but we believe that should be at your discretion – not based on insurance rules.

No Waitlists.

Onward Growth does not maintain waitlists – we want you to have access to the care you need when you need it. You can self-schedule through our private portal, or you can reach out to us to find a time that works for you. All out autism evaluations are conducted by an expert in neurodivergence, Dr. Tabitha Hapeman.

The Insight You Need.

Many adults spend years feeling different without understanding why. If you’ve ever wondered whether autism could explain your experiences — your patterns of thinking, communication, or social fatigue — you’re not alone. At Onward Growth Psychiatry, we provide comprehensive autism evaluations for adults in Arlington, Virginia, helping you gain insight, relief, and direction.

Why Seek an Autism Evaluation as an Adult?

Autism often goes unrecognized in adults, especially in those who are high-masking, high-achieving, or have developed ways to “blend in.” Masking can help you blend in and be successful, but it’s also exhausting. Many adults seek an evaluation once they’re burned out or at a crossroads in life. Others have thought about it for years and haven’t found the right provider yet.

An adult autism evaluation can help you:

• Understand lifelong patterns in social, sensory, or communication differences
• Figure out how to unmask and protect your energy while still reaching your career goals
• Define the therapy, workplace accommodations, or coaching you need
• Replace self-doubt with self-understanding and self-acceptance

Specialty in High-Masking and Late-Identified Adults

High masking adults are especially concerned about investing in an adult autism evaluation. You may look like you have it all put together, but on your inside you’re drowning. We have special expertise in evaluating high-masking adults. Most of our clients are women, professionals, or parents who have spent years adapting, often at the expense of their mental health.

We understand that masking can make the evaluation process feel complex or uncertain. That’s why we don’t use computer-based testing or assessments originally designed for children. Our process was designed for high masking people – the goal is to understand your lived experience, not present you with endless multiple-choice questionnaires.

What to Expect

Our evaluations are thorough, evidence-based, and supportive.
You’ll meet with a psychiatric provider experienced in adult and late-identified autism, who will:

1. Review your developmental and life history
2. Conduct a structured interview to gain deep understanding of your lived experience
3. Provide a detailed diagnostic report with personalized feedback and next steps

You’ll leave with clarity by the end of your appointment – you don’t wait weeks or months to receive your results.
