Juan Abarca Campal (born October 25, 1944, Ciudad Rodrigo) is a Spanish physician and surgeon, businessman and founder of the HM Hospitales group.

He lived a happy childhood in the middle of the post-war period, although full of small accidents.

This brought him closer to traumatology, which was practiced by his cousin Ernesto, whom he accompanied in his first interventions.

[2] His training was completed after practicing as a Resident and Assistant Physician in General Surgery at the La Paz University Residence (1970–77), alongside Dr. Fernández de Lis; and he was also a volunteer assistant to Dr. Carlos Moreno, of the Jimenez Díaz Foundation.

[5][6] He is the author of several scientific articles: 'Alterations of Plasma Proteins in Gastric Neoplasias', 'Aortic Stenosis', 'Hereditary Telangiectasias of the colon', 'Surgical anomalies of the angle of Treitz', 'Argumosa: life and surgical work', 'Evaluation of the D'Or Technique in esophageal hernias' and 'Total Duodenopancreatectomies (personal experience 11 cases)'.
