ADHD & Autism Psychological Services and Advocacy is an agency that specializes in providing state-of-the-science assessment, treatment, educational, and advocacy services for persons across the lifespan. We have offices in Utica, New York, and Syracuse, New York, and provide consultation and training services across New York State.
As our name indicates, we specialize in ADHD and Autism Spectrum Disorders (more broadly, developmental disorders). However, we also provide our expert services to populations of children, adolescents and adults with other mental health (e.g., depression, anxiety, adjustment problems) and learning disorders. As you are likely aware, persons with one type of problem (e.g., ADHD, Autism) typically present with other types of problems (e.g., mental health or behavioral disorder). In fact, it is the rule rather than the exception that the persons with whom we work present with multiple problems that cut across multiple domains of functioning (e.g., mental health, academic, substance use) and across multiple settings (e.g., home, school, community). As one example, persons diagnosed with ADHD are one- to two-thirds likely to have co-occurring learning disorders, anxiety disorders, depression, conduct disorders and are at significant risk for early onset substance use, poor school attendance, high school dropout, juvenile delinquency and poor occupational functioning. Thus, although we specialize in ADHD and Autism, it may be more appropriate to say that we specialize in assessing and treating persons (children and adults) with emotional, behavioral, social and academic difficulties.
Our training and consultation services are embedded within a positive and strength-based framework and are directly aligned with the overarching philosophy that is engrained in every facet of our services. In all of our endeavors, we strive to share the wealth of knowledge that will enable children, adolescents, and adults to achieve their full potential, to help caregivers and teachers to become powerful change agents, and to facilitate the broader community’s recognition of persons with cognitive, emotional and behavior disorders as valuable members of the community.
Our philosophy is embedded in every aspect of what we do, and in all that we intend to accomplish. Beyond the clear human value of promoting this philosophy, we believe that this approach makes important economic sense. In our nation's current state of economic affairs, it is vital that we employ strategies that are not simply reactive to developmental, behavioral, and emotional difficulties, and strive to reduce deficits. Thus, the strategies that we utilize are proactive and strength-based, and therefore offer much more in promoting the long-term growth and promise of children, adolescents, and adults. Such positive outcomes will surely reduce the incredible economic burden of the current system of care by providing persons with supported opportunities to flourish and creating, as a byproduct, a reduced need for services.
We hope that you will feel encouraged and supported in every step of your experience with us. Your care and well-being is our top priority.
