In 2009, WIN acquired Scanlon and Associates the developer of the DrugPak Software Suite. DrugPak is the industry’s leading drug and alcohol program management software. Our special access to this software has allowed us to create customized solutions to meet our client’s specific needs.

Our relationship with DrugPak has also allowed us to add our Back Office Support Services which we provide for other Third-Party Administrators. These TPA’s have been able to utilize our technology and expertise to make their own operations more effective and efficient and to improve the services they are able to provide to their clients.
