diagnosis

Get clear answers, compassionate support, and a better understanding of yourself.

Whether you’ve always felt different from others, recently started exploring neurodivergence online, or are deep into late-night Google searches about masking and sensory overload—you are not alone. Many adults come to autism testing later in life, especially those who’ve learned to blend in, overcompensate, or put everyone else’s needs ahead of their own.

If you’re wondering whether autism is part of your story, I’m here to help you find clarity—without judgment, pressure, or pathologizing.

Get an Autism Assessment That Makes Sense of Your Life

I offer neurodiversity-affirming autism testing for adults (ages 18 and up), both in-person here in Northfield, Minnesota and online for clients across 42+ PSYPACT states. My approach is collaborative, trauma-informed, and designed to work with your brain—not against it.

We’ll explore questions like:

  • What’s the difference between autism and ADHD?

  • Could my social exhaustion or “weirdness” actually be neurodivergence?

  • Why have relationships always felt confusing or overwhelming?

  • Is it too late to get diagnosed?

Spoiler: It’s not too late. You’re not too old. And you’re definitely not “too much.”

What You’ll Get from an Adult Autism Assessment

By the end of our process, you’ll have:

✅ A clear answer about whether autism is part of your diagnostic picture
✅ A thorough personalized report (great for accommodations at work/school or just your own peace of mind)
✅ A better understanding of how autism may be interacting with ADHD, anxiety, trauma, or depression
✅ Supportive, actionable next steps (accommodations, therapy, coaching, or community resources)

We use the current gold standard assessment protocol for an adult autism evaluation, and break this down into a simple 2-step process...

Step 1: Clinical Interview & Testing

Tele-health or in-person.

2-3 hours

  • We’ll meet either in person or via telehealth.

  • We’ll explore your history, symptoms, social experiences, sensory sensitivities, masking patterns, and more.

  • I’ll also use standardized autism assessments for adults, plus screeners for ADHD, trauma, anxiety, and depression (because these things often overlap).

  • If helpful, you can invite someone who knows you well (partner, sibling, parent, best friend) to contribute observations.

Step 2: Feedback & Written Report

Tele-health or in-person.

60 minutes

  • You’ll receive your full report (usually within 3–7 days—I know, that’s fast!).

  • We’ll meet again to review your results, talk through next steps, and make sure you feel supported moving forward.

Still Wondering If You Might Be Autistic?

You may be navigating late-diagnosed autism, especially if you:

  • Felt like an outsider growing up—even if no one else noticed

  • Struggle with unspoken rules, small talk, or group conversations

  • Experience sensory overload (certain sounds, lights, fabrics, etc.)

  • Mask so well that people say you “don’t seem autistic” (ugh, we know)

  • Are a woman, nonbinary person, or trans person who’s learned to overachieve and compensate

You are absolutely not alone. Many of the folks I work with have been quietly wondering for years—and finally take the leap to find clarity and self-compassion through autism testing.

No-Show / Late Cancellation Policy

Because your autism assessment reserves 3+ hours of dedicated time, we require at least 24 hours’ notice to cancel or reschedule.
Missed appointments or late cancellations may result in a $265 fee, or in some cases, the full appointment cost.

We get that autism and ADHD can make scheduling hard—our goal is to work with your brain, not against it. If you need help staying on track, just reach out. We’re here to support you through the process.

Still Thinking About It?

If you're still reading, that’s already a great sign. Sometimes it takes a few scrolls (and maybe a snack break) to decide. If now feels like a good moment, go ahead and take the next small step.

We’ve made scheduling as easy as possible—just a few clicks, no paperwork yet, and we’re here if you need help along the way.
