What People Are Saying

“Brendan is amazing. I’m not sure what I’m more excited about – the way he helped my son, or the way he helped us understand what was going on with our son. It made such a big difference to have him explain how our son sees things, and to be able to get some advice on how best to help him.”

“I highly recommend Mr. Mahan as a resource for schools to effectively meet the needs of students with ADHD through an understanding of the different faces of the disorder and strategies for staff to utilize across disciplines and settings.”

“I was able to attend Brendan’s ADHD workshop at MSAA in 2017. Topics included the role of executive functioning, the impact of repeated failure, and effective strategies for instruction. His presentation was engaging and practical! His experiences allow him to provide so many real-life examples when it comes to supporting those with ADHD. I loved the presentation so much that I have planned multiple professional development activities at my school that involve Brendan working with some of our teachers, and all of our paraprofessionals. The feedback that I have received about his PD offerings at our school has been phenomenal. I would certainly recommend attending one of his workshops, as well as involving him in professional development for any school district.”

“Brendan’s workshops are a must see no matter where you or your child are in the process of navigating ADHD. I highly recommend it- wish I had seen this years ago.”
