My Ideal Client

I specialize in giving a range of gold-standard assessments to children, teens, and to adults. For children, I can provide autism, ADHD, psychological, academic, and cognitive assessments using cutting edge assessment tools. For adults I specialize in giving gold-standard autism or ASD assessments. Please note, that I look at all overlapping factors to give you a clear picture on your mental health and a way forward.

My Approach to Helping

In regard to my experience, I have administered, performed and consulted on over a thousand neurodevelopmental, cognitive, and psychological evaluations on children from 18-months through adulthood using state-of-the-art assessment tools and evidence-based measurements to diagnose even the most difficult cases. Furthermore, due to my experience, I am able to test individuals within one day. Furthermore, I write a full report within one week of your in-person visit. This way, you and your family do not have to wait months for the report, or keep returning for further testing sessions.

My Personal Beliefs and Interests

Dr. Thatcher is passionate about mental health and truly enjoys providing psychological testing to those seeking help. He is originally from the Midwest and grew up on a small farm. In his free time, he loves spending time with his family, hiking, watching movies, and traveling.
