National Disability Rights Network

The National Disability Rights Network (NDRN) is the nonprofit membership organization for the federally mandated Protection and Advocacy (P&A) Systems and the Client Assistance Programs (CAP) for individuals with disabilities.

Walt Derengowski and his team are very professional, thorough, proficient, and knowledgeable.  They take time to explain matters that may be unclear and they were very flexible in scheduling. Also noteworthy is the fact that they very quickly grasped the nature of the work that we do.  We’re a nonprofit membership organization, however, in many ways we are unique. Walt’s team demonstrated an ability to grasp our unique qualities and tailor their approach to the audit accordingly. I absolutely would recommend them and definitely intend to continue using GRF!
