Brynn Systsma – Clinical Director

Psy.D., LP

Dr. Brynn Sytsma serves as our licensed Pediatric Neuropsychologist and Clinical Director. She provides comprehensive psychological and neuropsychological evaluations for children and adolescents from early childhood through high school.

She specializes in the assessment of neurodevelopmental conditions, including Autism Spectrum Disorder (ADOS-2 certified), ADHD, developmental disabilities, and learning disorders. Dr. Sytsma also evaluates individuals who present with emotional or behavioral concerns, trauma-related conditions, FASD, and medical or neurologically based concerns.

Her evaluations are individualized and designed to provide clear diagnostic answers with practical, real-world recommendations. She works closely with families, schools, and multidisciplinary teams to ensure findings translate into meaningful support across settings.

Dr. Sytsma approaches her clinical work as both a diagnostician and an advocate. She is committed to helping families leave the evaluation process with insight and concrete next steps so they can confidently advocate for and support their child. Her style is strength-based and neurodiversity-affirming, grounded in the belief that understanding a child’s diagnosis should reduce confusion, not add to it.

In addition to her clinical work, Dr. Sytsma provides supervision to clinicians, supporting high standards of care and ethical practice. As Clinical Director, she works to improve clinic operations. 

Dr. Sytsma also incorporates animal-assisted therapy into her work alongside her certified therapy dog, Leo. Outside of work, Leo and Dr. Sytsma enjoy exploring local trails, visiting community events, and spending time with family.

I have twelve years of clinical experience counseling individuals struggling with issues including anxiety, depression and trauma. I greatly value providing you with an authentic and judgement free experience. I find my clients appreciate my direct approach. In other words, I will give it to you straight. We will work towards what you want in life and that often means moving through what one historically avoids. What lies on the other side of the pain is the life you were meant to live. I also enjoy incorporating humor into our work together. Anxiety, depression and trauma often steal our joy and sense of humor. Joy and humor can be found again.
