She completed her APA-accredited internship at The Guidance Center, Inc. in Leavenworth, KS,  where she trained in child and family services alongside neuropsychological assessment, and was accepted to a postdoctoral fellowship at CBTeam in Lexington, MA, where she received training and supervision from experts who helped lead McLean's OCDI and Boston Children's Hospital in CBT and ERP. Dr. Colby also completed a clerkship in neuropsychology at NAC Clinic (Previously NP Evaluation) in Brookline, MA.
