It is with great sorrow that we (Class 79) announce the untimely passing of one of our most beloved classmates- Mannny Ong.

He was a son, brother, friend, classmate, physician, lover, husband, father, & grandfather. In his short but fruitful time, he touched numerous lives - his memory and legacy will not be forgotten. He was a practicing neonatologist/perinatologist in the Tampa, Florida area and directed the neonatology unit in his hospital until his demise.

Manny was married to our classmate, Annette Sanchez, MD. Together, they have 2 daughters and 2 grandchildren. They are generous donors to our charitable projects most notably the USTMD 79 GK Village in Bantayan Island, Cebu.

Please remember Manny Ong and his family in your prayers. Class 79 will miss Manny but we take comfort in knowing that he lived his life as a true Thomasian physician with competence, commitment, compassion, and dedication to his family, friends, patients, and most of all, to those in need.

With deep sorrow and sympathy for Joven and his family, we mourn the death of his childhood sweetheart and beloved wife, , Lily , on August 17, 2016. She is now resting in peace with God's everlasting love and happiness. We can't feel saddened over the loss of those we love without first remembering the joy of loving and being loved by them.

The real sadness would have been never having them in our lives at all. God has blessed our classmates, Lily and Joven with love, faith, success, prosperity, 4 children, 8 grandchildren and achievements which have given them JOY. We thank Lily and Joven for their support and contribution to the USTMED Class 1958 Legacy, Celebrations and Reunions. Read the Profiles of their family and professional achievements , their avocations and message in our book " The Thomasians 2008 Golden Jubilarians ". Let us celebrate Lily's life, her achievements and success. May God comfort and bless Joven and their family with the Gifts and Fruits of the Holy Spirit always !

We grieve of the loss of a classmate and great friend Violeta (Lily) Rivera - Mangahas. We are blessed with happy memories of Lily. We have played many rounds of golf together, by the way Lily is the best female golfer of UST Medical class of ’58. We have visited each other’s home many times even when they were still in Indiana some twenty odd years. My wife and I get together with Lily and Joven at least once a year, the latest one was February this year. Lily has been very active in reuniting the class of ’58. At least once a year for two years before the incomparable dance presentation, dubbed as dancing Queens, Lily would assemble all participants, hire a dance instructor to teach us and practice the different dance moves for one week at a time at their home at The Villages of Florida. This dance was presented at our Golden Jubilee in conjunction with annual USTMAAA at Las Vegas.

Through Lily & Joven the class of ’58 continue this yearly reunion, of late working with Bill & Mary Oh also class of ’58. It is fitting and a tribute to Lily that the reunion scheduled by Lily and Bill Oh in September 2016 be postponed for next year.

Lily you will be sorely missed.

It was Joven & Lily that proposed me for the 2014 USTMAAA Most Outstanding Alumni for Community Service Award. Also they support the American Foundation to Aid the Poor.
