Thank you to our DSP heroes!

Alpha is able to accomplish our goals because of the dedicated work of our DSP team. It is important to support our DPS team and their needs so that we can continue providing the best support for our individuals to live their lives to the fullest. Be sure to thank a DSP in your community for all that they do everyday!

Our dedicated employees, board, donors, families and community partners have stood with us as we reached new heights, created new systems to meet the support needs of those we serve, and expanded to meet the needs of those wishing to receive our services.

Being out in the community with someone he knows and is a consistent presence in his life makes a world of difference to my son. I have really appreciated the continuity provided by Alpha’s Community Access staff and the fact that my son looks forward to his time with Ramsey.

Alpha is a very comfortable agency to live with. I’ve lived in Alpha for over 8 years. I’ve met a lot of new friends in the past 8 years.
