Here, independence day is every day.

At SESDAC, we see the potential for independence in everyone. It’s what makes us so committed to helping those with disabilities achieve full integration through the development of both social skills and job skills. Our services have helped hundreds of people move on to paid employment, independent living, and a rich, well-rounded lifestyle. Although everyone receiving our services is unique, and every situation is different, the goal is always the same. We provide the support that leads to a seamless transition to the adult service system and helps navigate the years between school and age 21 by fostering development and offering guidance.
People who take advantage of our services come from a wide variety of backgrounds and needs. We recognize that everyone’s different, and we make sure that no matter how much or how little support you need, that you feel empowered to live the life you want. Everyone brings their own hopes, interests, and personality, and together we create a community of active, vibrant, essential members of society. We hope you’ll choose to be a part of that community.

To truly tell our history, you’d have to tell the histories of every family we’ve worked with. Every person we’ve touched, and who touched us. But the real credit goes to those families and professionals who started SESDAC, through which thousands of lives have changed.
