Insight Collective’s mission is to provide comprehensive assessment and treatment to young adults and children utilizing the best standards of care. Each Insight Collective professional contributes specialized knowledge in their chosen field to allow for a thorough understanding of our clients’ needs. Through in-depth knowledge of our client’s unique strengths and weaknesses across multiple areas, our team is able to devise a more focused and effective treatment plan. We understand that accessing treatment interventions is difficult to navigate alone. To help our clients navigate the specialized recommendations, all of our families are matched with a facilitator who will provide continued help and support while our families work to put treatment services into place.   

Taking individual steps towards a final diagnosis or treatment plan can be laborious and time consuming. Oftentimes, completing a neuropsychological assessment is only the first step to understanding our client and their needs. At Insight Collective, we strive to eliminate the step-by-step referral process and instead provide our families with a transdisciplinary assessment at one convenient location. Open communication between team members allow for more timely results. Providing treatment quickly and efficiently is especially important when working with children, so that they may benefit from intervention during critical developmental periods. Fewer appointments also equate to fewer missed school days.
