Our counselors have the credentials to treat both addiction and mental health. Many people diagnosed with a substance use disorder (SUD) also suffer from a co-occurring mental health or behavioral disorder. This is known as a dual diagnosis. Individuals with a dual diagnosis require an integrated treatment plan that addresses both disorders as interconnected mental health issues. According to the National Survey on Drug Use and Health (NSDUH), 45 percent of people with addiction have a co-occurring mental health disorder.
