Five years removed from the spectacular Upsilon centennial celebration held at the PICC in Manila in November of 2018, Asia's first and the Philippines' most prestigious fraternity, the UPSILON SIGMA PHI, marked its 105th foundation anniversary with a gathering of fellows at the Ang Bahay ng Alumni in U.P. Diliman last November 27, 2023. Over 200 Upsilonians attended the event which was sponsored by the Upsilon Sigma Phil Alumni Association headed by President Yari Miralao '88 and Chairman Roel Castro '84 and the USPAA Fellowship Committee headed by Charvy Parra '89.
