It is my goal to provide you with information and Answers to help change your life or the life of a loved one for the better.
Mental Health assessment is an incredibly powerful and accurate way to learn how the mind works when done correctly. Many providers are trained only to conduct brief or vague assessments. I use complete neuropsychological batteries for testing and assessment services for Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD), in person and through telehealth.
I have conducted many ADHD and ASD evaluations for people in the Twin Cities Metro Area, working with elementary, middle school, high school, college, and graduate school students and adults already in the workforce from a wide variety of backgrounds.
ADHD and Autism Spectrum Evaluations
I offer testing to individuals ages five and up. Seven-year-olds are the youngest patients I diagnose due to the age range of the tools I use, although I generally recommend testing for patients ages seven years and up.
Ages 7 and Up
It's crucial for me to observe not only the facial expressions of someone undergoing an ADHD evaluation, but also their body language. It's equally important for me to not just identify which activities are challenging, but also to observe how a person's mind and body react when faced with difficult tasks.
In-Person Testing
Catching ADHD and ASD early and taking action can make a profound difference.
When parents and doctors can spot ADHD or ASD early, they can identify and provider tools and accommodations to help kids grow and learn. This can have a big impact on how well they do in school, get along with others, and feel happy overall. The recommendations at the end of my assessment reports include specific recommendations based on the needs of the client.
6 million

It is estimated that 3 in 10 children in the United States have ADHD.
Hi. I’m David Nathan.
I have specialized in mental health assessments since before finishing grad school. I completed my Assessment Practicum, Doctoral Internetship and Doctoral Fellowship at the Discovery Clinic (the University of Minnesota Pediatric Neurological Assessment clinic), Fraser and Stone Arch Psychology, respectively. I find helping people learn more about how their mind works incredibly fulfilling. I also enjoy helping clients and their families get answers and help them reduce shame, guilt and stigma related to mental illness. I enjoy providing specific recommendations based on the unique results profile of each clint. I offer these recommendations to patients to help them draw in their strengths and reduce their difficulties in their day-to-day life. I want my patients and their families to walk away happy, well-informed, and confident about their future.

We met with Dr. Nathan for my son, and things went very smoothly. He explained everything in great detail in language that was easy to understand. Following our evaluation, Dr. Nathan gave great advice on next steps and kept an open line of communication. To top it all, the timing to get in was speedy.
