With this objective, CER (Center for Rheumatic Diseases) was born, which in a short time became a reference institution dedicated to the prevention, diagnosis and treatment of rheumatological pathologies.
Since 1999, the clinical research area has been incorporated, generating a specifically trained multidisciplinary team.
As of 2004, CER became the CER Medical Institute and expanded its attention to other specialties, keeping its mission intact: Improve the quality of life of our patients bringing science closer to the community.
