Who was the first doctor of Plaridel, Misamis Occidental?

To those who are old enough to remember, the name that comes to mind is Dr. Juan A. Vallejo.
In the 1930's, he was assigned by the Bureau of Health Services to Plaridel as the Municipal Health Officer (MHO) and to establish the Rural Health Unit (RHU) of the municipality.
But, Dr. Vallejo was not a native Plaridelian. He was a full-blooded Spanish gentleman, who was born in Barcelona, Spain in 1900.

His family migrated to the Philippines in 1905 and settled in Pasay City. This was at a time when the Spanish colonial reign has already ended and the Americans have established their own colonial government.
He studied and obtained his Physician's degree at the Universidad de Santo Tomas (UST), Manila, in 1925. UST, the oldest medical school in the country, was run by the Dominicans, Spanish friars of the Order of Preachers.
The state of the public health system in the 1920's was described as having an acute shortage of doctors, nurses, and sanitary personnel.
And yet, in spite of the country's dire need of physicians, Dr. Vallejo could not find employment. This was because of his Spanish citizenship.
So, he renounced his Spanish citizenship, applied for and was granted the status of a naturalized Filipino citizen. He was then accepted by the Philippine Health Service (today's Department of Health) as a physician, to work in the government's public health service.
His first tour of duty was his assignment to Siquijor, Negros Oriental. He headed a team that would later be called the Rural Health Unit (RHU). Also in that team was a nurse named Felicidad Curamen, a winsome Genuine Ilocana from Paniqui, Tarlac.
Juan and Felicidad fell in love and became man and wife in 1928. Their marriage was blessed with seven children. The eldest, Salud was born in Siquijor, while the rest were born in his next place of assignment. Here's a family picture, circa 1948:
