The greatest achievement ever made during Connon's administration was the granting of the charter as a university to the college on February 19, 1975.

Connon's first term was marked by the expansion of the college and its professionalization, began under Brother Chrysostom Peter Clifford, who assumed the post of dean of the college, succeeding Brother Lambert Edward Chisholm, its post-war re-founder.

As auxiliary visitor, Connon, using De La Salle College as a base and as the mother institution, opened the novitiate in Baguio in 1951, the scholasticate on Taft Avenue in 1960, and the junior novitiate (also on Taft Avenue) in 1959.

It was during Connon's second term that the position of director (superior) of the Brothers' Community was separated from the presidency of the college.

In the 1960s, Connon, in tandem with the rector of the Ateneo de Manila University at that time, worked for the founding of the Asian Institute of Management, a graduate school of business for Southeast Asia.
