About us
Psychologists and psychiatrists under one roof
Alethia is a clinic with psychologists and psychiatrists in the heart of Copenhagen. We offer qualified assessment, medical treatment, and therapy for adults, all in one place, with a team that knows your full history from day one.
Our approach
The name Alethia comes from the Greek word for truth, αλήθεια. It reflects our fundamental belief: that clarity and understanding are the first steps toward a better life. We work from the premise that an accurate assessment is the foundation for meaningful treatment.
With us, assessment, diagnosis, and medical treatment are connected from the first consultation. You avoid being sent back and forth between different providers. Our psychologists and psychiatrists work closely together on each client, allowing us to adapt the treatment plan continuously.
We use internationally recognized diagnostic tools, including DIVA-5 for ADHD and ADOS-2 for autism, in accordance with Danish National Health Authority clinical guidelines. Our goal is always the most accurate assessment possible, so you receive the right treatment from the start.
What sets Alethia apart
Multidisciplinary
Psychologists and psychiatrists under one roof. You can start medication immediately after diagnosis, no additional referral needed.
