Our Professional Relations Team

Our Ambassador Team

We exist to serve and connect with other professionals in our communities. Our directors and community ambassadors are available to answer questions, support our clients and be a connection to professionals in the community.

Community Ambassadors & Business Development

Each region at Sandstone Care has an ambassador. Our ambassadors are responsible for networking and building connections to community providers including non-profits, advocacy groups and treatment providers. They coordinate trainings for professionals to earn CEU's and work tirelessly for Sandstone Care and their clients. Additionally our ambassadors help create a personalized aftercare plan that includes a warm handoff to another provider as well as other resources.
