About Me.

Dr. Erin Yosai is a licensed psychologist and nationally certified school psychologist with a passion for helping individuals and families better understand how their minds work—and how that understanding can guide meaningful personal and academic growth. With over a decade of experience in assessment, clinical supervision, and higher education, she offers comprehensive psychological evaluations that are both scientifically grounded and deeply personalized.

​

Dr. Yosai specializes in psychoeducational and neuropsychological assessment for children, adolescents, and young adults (e.g., 6-26), and beyond into adulthood. Her evaluations integrate cognitive, academic, emotional, and behavioral data to offer a clear picture of functioning and to support informed decisions at home, school, and in the broader community. She is particularly committed to providing affirming, actionable insights that reduce stigma and foster confidence.

​

Her areas of expertise include:

• Learning Disability & Dyslexia Evaluations

• ADHD & Executive Functioning Assessments

• Autism Spectrum Disorder Evaluations

• Neuropsychological Testing for Developmental and Acquired Conditions

• Emotional-Behavioral & Mental Health Evaluations

• Consultation with Families, Schools, and Professionals​

​

Dr. Yosai’s approach is collaborative, strengths-based, and responsive to the needs of each client. She values the lived experiences of the individuals she works with and practices from a lens that is neurodiversity-affirming, trauma-informed, and culturally responsive.

​

Originally from Kansas, Dr. Yosai began her journey into psychology and education at Baker University, where she developed her passion for child development and learning. She went on to earn a Master’s degree in Psychological Science from Montana State University in 2012, followed by a Ph.D. in School Psychology from The University of Montana in 2017. Her clinical training included an APA-accredited internship and postdoctoral fellowship at the University of Illinois’ Disability Resources and Educational Services office, where she worked with diverse college students navigating learning, attentional, and emotional challenges.

 

Dr. Yosai later served as an Assistant Professor at the University of Northern Colorado before returning to Kansas. She currently serves as Associate Professor of School Psychology and Clinic Director in the Department of Educational Psychology at the University of Kansas, where she supervises Ed.S. and Ph.D. students in School Psychology, as well as Counseling Psychology doctoral students, in their assessment work at the student- and community-centered Outcomes, Assessment Services, & Intervention Supports (OASIS) Training Clinic

​

Seeing firsthand the need for accessible, high-quality assessments across the region, Dr. Yosai launched her private practice to offer families and professionals timely, expert evaluations and consultation services. Her goal is simple: to demystify the assessment process, provide clear answers, and help each client move forward with confidence.
