Our Story

In 1983, Martin and Rosalie Landholm opened the doors to the first privately owned and operated DDA in Idaho. After a distinguished eighteen-year career working for the Department of Health and Welfare, Martin applied his knowledge and experience to create a company that would change lives. Currently, GSDC serves hundreds of individuals at four locations. Martin and Rosalie continue to run a flourishing business as well as create lasting relationships in this exceptional establishment.

In 2019, the company was sold to Lori Jo Poole, a Licensed Clinical Social Worker and GSDC’s Clinical Director of Adult Services, who has been with the company for over 20 years. Under our new ownership, we take pride in maintaining the same excellent levels of service and professionalism established by the Landholms, while looking forward to further development and growth in our existing and future relationships. We have a great team of compassionate, knowledgeable and experienced professionals and paraprofessionals who are passionate about seeing our participants thrive.
