Gregorio Alvior Y Tolentino was the first president of Alimodian after its separation from Leon. He was sworn into office on January 1, 1919. As the town head for many years, he did much for the progress of his town. He encouraged the people to plant bananas so that they could have food when staple crops failed. He also required the people to have galvanized iron roofs to prevent the havoc wrought by fires which caused damage in previous years.
For all the good deeds that he did for his town, he was considered the father of his community.
