You know the feeling. A client arrives and something doesn't quite fit. The anxiety diagnosis made sense – until it didn't. The ADHD label explained some things, but never all of them. The woman you've been seeing for three years is finally doing better, except she's still exhausted, still burning out socially, still can't explain why the world feels like it requires a costume.

You've wondered. You just didn't have a framework.

Autism is in your waiting room.
It's been there for years.

You don't have to be a neuropsychologist to need this training. You refer these clients. You read the reports that come back. You're the one in the room when a 38-year-old finally gets an answer – and doesn't know what to do with it. Most graduate programs gave you a single lecture on autism: a checklist, a few case studies, the classic presentation.

What they didn't give you was a real clinical framework for the world you're practicing in right now. Adults who were missed for decades. Women who were called anxious. Teens whose every diagnosis was a near-miss. Clients who came to you for one thing and slowly, undeniably, started looking like something else entirely.

This two-day intensive is built for exactly that.

Two Days. Two Experts.

Day 1 · December 10

Assessment, Diagnosis & Clinical Clarity

with Celine Saulnier, PhD
“Know what you're looking at.”
  • Stop missing the masked presentation – in women, girls, and gender-diverse clients
  • Differential diagnosis made clear: ASD vs. ADHD, anxiety, OCD, and trauma
  • Identify undiagnosed adults – including the client you've been seeing for years
  • Gold-standard assessment tools explained for clinicians at every level
  • Turn evaluation findings into a treatment roadmap that actually drives care
  • Write neurodiversity-affirming reports that families and providers can act on
Day 2 · December 11

Therapy with Autistic Clients: ACT · CFT · DBT

with Jennifer Gerlach, LCSW
“Know what to do about it.”
  • Adapted ACT, DBT, and CFT – because standard protocols don't fit autistic clients
  • Autistic burnout, RSD, shutdowns, and meltdowns: recognize and treat them
  • Support the client who just found out they're autistic at 38
  • Build a therapy environment that actually reduces barriers to engagement
  • Couples, families, and teens – adapted approaches for every relationship context
  • From a clinician who has been on both sides of the couch

Two of the Best in the Field. In the Same Room.

Clinical expertise. Lived experience. The kind of insight you can't get from research alone.

Jennifer Gerlach is a psychotherapist specializing in the intersection of mental health, trauma, and neurodiversity, utilizing interventions informed by ACT, CFT, DBT, and EMDR. She is the author of The Psychosis and Mental Health Recovery Workbook, writes the Psychology Today blog “Beyond Mental Health,” and has trained hundreds of clinicians nationwide.

What sets her apart is simple: she has been on both sides of the couch. As an autistic clinician herself, the depth she brings to this work is something no credential can replicate.

Assessment, Diagnosis &
Clinical Clarity

In a world where 1 in 36 school-age children in the U.S. is diagnosed with Autism Spectrum Disorder (ASD) and many adults are being diagnosed for the first time, understanding this multifaceted condition is not just crucial – it's transformative. But how do we move beyond outdated diagnostic processes and perceptions of treatment?

Join Celine Saulnier, PhD, a leading clinical psychologist, researcher, and author of the Vineland Adaptive Behavior Scales, Third Edition, for a groundbreaking training that demystifies the autism spectrum. This isn't just about diagnosis; it's about embracing the full spectrum of human potential.

In this training, you'll discover how to:

  • Confidently utilize gold-standard diagnostic measures with clients of all ages, ensuring accurate and respectful assessments.
  • Identify and understand the intricate influences of age, language, cognition, gender, and cultural backgrounds on ASD to provide tailored support.
  • Address co-occurring conditions that often complicate the diagnostic process, ensuring clarity and compassion in care.
  • Select meaningful, evidence-based interventions that empower individuals with autism, rejecting punitive approaches in favor of fostering genuine growth and self-advocacy.

This training emphasizes compassionate, effective care, rooted in evidence-based strategies. You'll leave with a toolkit that not only enhances your clinical practice but also supports individuals on the autism spectrum in a way that acknowledges and celebrates their unique strengths.

Therapy with Autistic Clients:
ACT, CFT, DBT & Self-Compassion

The correlation between autism and anxiety, phobias, suicidality, depression, and other mental health disorders is well-established. But the complexities involved in treating autistic and other neurodivergent clients often result in less-than-ideal clinical outcomes.

Join Jennifer Gerlach, LCSW, a neurodivergent psychotherapist and author, in this one-of-a-kind course focused on giving you the confidence and specialized intervention tools you need to maximize your therapeutic results in working with teens and adults with diagnosed or suspected autism.

You will walk away with the ability to:

  • Recognize signs of masking in your assessment process to get to the underlying diagnosis.
  • Apply neurodiversity-affirming ACT, CFT, DBT, and self-compassion interventions for depression, anxiety, and other mental health concerns.
  • Minimize verbal and non-verbal communication barriers and sensory processing differences in the therapeutic process.
  • Employ interventions for families, couples, and group work with neurodivergent youth and adults.

From the People Who've Been in the Room.

“Celine was a fantastic presenter – one of the best trainings I've attended in a long time. She covered both the big picture and the nuances – I could apply it the very next day.”

Everything You Need to Know

You don't have to…but we recommend it. Each day is designed to stand alone. Day 1 focuses on assessment and diagnosis with Dr. Saulnier. Day 2 focuses on therapy and treatment with Jennifer Gerlach. You can register for one or both – though attending both gives you the complete clinical picture and a bigger discount.

Yes – and it's designed with you in mind. Most attendees are therapists and counselors, not evaluators. Day 1 explicitly addresses what every clinician needs to know: how to recognize ASD, when to refer, how to read evaluation reports, and how to work with late-identified clients. You don't need to administer the ADOS-2 to need this training.

Up to 6.25 CE hours per day, up to 12.5 total for both days. A certificate of completion is provided upon finishing the training. Click here to see full CE details.

Registration opens at 7:30 AM. The seminar begins at 8:00 AM and concludes at 4:00 PM. Lunch is from 11:50 AM – 1:00 PM. There is a 15-minute morning break and a 15-minute afternoon break.

Free shipping on the book is available for US addresses only.

Yes. An on-demand recording option is available for clinicians who cannot attend in person or via live stream. On-demand participants receive access to the full recording and all materials, and are eligible for CE credit upon completion of a post-test.

NOTE: No additional discounts or coupons may be applied to this course.
