Alpha SLS has given our daughter independence as well as safety. Alpha recognizes that each person’s needs are unique. We are so grateful for the personal attention of the daily caregivers, supervisors and office staff. Medical and dental needs are organized and supervised by an RN. It is such a relief to know that her care plan will be adjusted as changes and her needs change. We cannot thank Alpha enough for the attention to details in the daily life of our daughter.

Alpha does a better job than me with the doctor appointments, medication management, and monitoring for changing health concerns. It’s such a relief as a parent to have alpha do such a great job with medical care.
