The Answers You Need, When You Need Them.
Many adults spend years feeling different without understanding why. Many of our clients have always felt like they didn’t fit in, even as they navigated school, career, and family. Most of our clients are working professionals, busy moms, and high achievers – yet they feel different or like they’re a social chameleon. Some have tried to be evaluated in the past only to be met with evaluators who only understood autism in children or in those who need profound levels of support.
At Onward Growth Psychiatry, we provide comprehensive autism evaluations for high masking adults in Northern Virginia, helping you gain insight, relief, and direction. Serving clients in all areas of Northern Virginia, including:
- Arlington
- Alexandria
- Fairfax
- McLean
- Reston / Herndon
- Vienna
- Great Falls
Complete Privacy
Many of our clients place a high priority on privacy. You may want to be evaluated, but you don’t want the results to be shared with your insurance company or your workplace. That’s why we specialize in private pay evaluations. Your results belong to you, not your insurance company. Receive insight quickly and with total confidentiality.
Why Seek an Autism Evaluation as an Adult?
Autism often goes unrecognized in adults, especially in those who are high-masking or high-achieving. Our high masking clients are seeking self-insight and deeper understanding of their needs. Our clients want more insight into how to communicate with their spouse or children, how to set better boundaries, and how to achieve their career goals without sacrificing their mental health.
An adult autism evaluation can help you:
- Understand lifelong patterns in social, sensory, or communication differences
- Navigate relationships, work, and daily life with less stress
- Access tailored therapy, workplace accommodations, or coaching
- Replace self-doubt with self-understanding and self-acceptance
Specialty in High-Masking and Late-Identified Adults
At Onward Growth Psychiatry, we have special expertise in evaluating high-masking adults. Most of our clients are women, professionals, or parents who have spent years forcing themselves to conform to social molds, only to feel exhausted and burned out in their 30s, 40s, or 50s.
We understand that masking can make the evaluation process feel complex or uncertain. Many of our clients are fearful of being disbelieved or gaslit. Our approach is deeply validating, helping you explore your experiences without judgment. You’ll be met with curiosity, not skepticism — and guided toward a clearer, more authentic understanding of yourself.
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:
- Review your developmental and life history
- Conduct structured assessments for autism and related conditions
- Provide a detailed diagnostic report with personalized feedback and next steps
You’ll leave with clarity — not just a diagnosis, but a roadmap for your growth and wellbeing.
