En nombre de Mari cruz Marin, su marido y sus dos hijas queremos agradecer al grandísimo equipo formado por el doctor Jorge Espinós, doctora Mercè Rosinach, Doctor Diez-caballero y a todo su equipo médico y de nutrición, la dedicación, profesionalidad, humanidad, preocupación y cariño con el que nos han tratado en todo momento. Les estaremos siempre agradecidos.
Fuimos a ver al Doctor Diez-Caballero por un diagnostico de Cáncer de estomago, un doctor me lo recomendó y he de decir que nos ha dejado muy tranquilos, por su profesionalidad, sobretodo su empatia y cariño.
Desde el primer minuto nos ha explicado con claridad todas las soluciones a nuestro problema, ha resuelto todas nuestras dudas y nos ha explicado como sera la intervención.
Muchísimas gracias por tu profesionalidad y empatia!!
Profesional de trato cercano y agradable.Desde el principio tuve la impresión de estar en las mejores manos posibles y esa opinión se ha visto reforzada tras la operación y los resultados obtenidos. La técnica utilizada fue la de laparoscopia. Lugar de la operación Teknon.
El Dr. Diez-Caballero me operó con técnica laparoscópica de un schwannoma retroperitoneal benigno. Fue todo fantástico y apenas se me notan las incisiones. La verdad es que desde el primer momento me causó sensación de confianza y de que estaba en buenas manos. Gracias Doctor.
El doctor Diez-Caballero me operó de la vesícula biliar por técnica laparoscópica LESS. Desde mi experiencia personal, su trato cercano y su extraordinaria profesionalidad hacen que le recomiende a todos aquellos que consideren ponerse en sus manos.
