[2] Early in life, he was also a student of Spanish painter Juan Fernández Corredor and Dominican painter Luis Desangles, whose workshop brought him into the circle of other prominent young artists and intellectuals like Abelardo Rodríguez Urdaneta, Manuel María Sanabia, Arquímedes de la Concha, Leopoldo Navarro, Adolfo García Obregón, and Francisco González Lamarche.

[3] After graduating from the Normal school, Grullón travelled to Europe to study art, settling in Paris where he eventually earned his degree in medicine in 1902.

He returned to his hometown of Santiago de los Caballeros to practice his specialties in Surgery, Obstetrics and Ophthalmology, acquiring national recognition throughout the years.

His parents were independentist merchant and political activist, Máximo Grullón Salcedo (1826-1877) and Eleonora Julia, who provided their seven children a careful education allowing them to excel from an early age.

[1] One of them being Eliseo Grullón (1852-1915), who was sent to Nanter, France where he obtained a humanistic and professional training that afforded him influence in the political sphere of his native country when he returned in 1874; a recognized writer and initiator of cultural initiatives, the elder Grullón played a hand in Spanish painter Fernández Corredor's stay in Santo Domingo.

There he met Cuban writer José Martí, and learned pictorial techniques under a Spanish teacher, surrounded by the Paris of the Belle Epoque.

[5] Despite initially travelling to Europe to continue an artistic career, motivated by anatomical drawing, he decides to study medicine in Paris, graduating as a doctor in 1902.

After returning to his native country, he assumes the family and medical responsibilities that lead to the abandonment of the life of the workshop and canvas.” This renunciation of brushes is so abrupt that his autobiography as a health scientist makes no mention of his artistic incursions.
