Who We Are

TTI is a private, not-for-profit agency that has been providing specialty mental health services and training in Michigan since 1987. We provide a wide range of community-based services and supports to adults with psychiatric disorders and to those with both co-occurring psychiatric and substance use disorders. We also provide services to children and adults with developmental disabilities and children with emotional impairment.

It is with unwavering commitment that we pledge to:

• Wisely use every ounce of our skill, creativity and resources to provide our consumers with opportunities to reach their dreams and goals.
• Promote maximum life outcomes for our consumers by the conscientious use of funds and resources in cost-efficient and beneficial ways.
• Show our consumers the highest esteem, respect, and appreciation we have for them, and our gratitude for the trust they have in us.
