A few years ago, I met with Laura from Alpha’s Community Access Program. And after our introductory interview, I had a good feeling that this might just be the perfect placement for my daughter. We often hear that we should strive for perfection but realize that it can be elusive. For my daughter, Alpha and Laura have achieved the perfect fit. Thanks for taking the time to get to know her and finding a meaningful activity that brings her so much joy!

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.
