Dr. Cason and Dr. Dumke met in 2007 and discovered a shared interest in working with neurodiverse individuals and their families. What started as the two of them conducting a few evaluations a month while still maintaining their respective therapy practices grew over time into what is now Insights, Colorado Assessment and Therapy. Insights now boasts a team of skilled and welcoming clinicians, a robust extern and intern training program, and a very busy diagnostic clinic where we serve hundreds of clients a month through therapy and evaluations. In the summer of 2020, Insights found its forever home in a 100+ year old house in City Park, where they have created an atmosphere that is warm and inviting. Both doctors are actively involved in the diagnostic evaluations and, while they no longer provide psychotherapy, they provide supervision and consultation to the Insights’ psychotherapy team.
