What Truong Buu Diep Foundation does
Mission
Our mission is to preserve and uphold a sacred space dedicated to honoring and advancing the canonization process of Father Truong Buu Diep a Catholic priest who was martyred during World War II in Vietnam for his courageous act of saving 70 innocent lives. Following his death countless individuals have reported experiencing graces and miracles attributed to his intercession. As a result an increasing number of faithful believers regard Father Diep as a powerful spiritual intercessor who conveys their prayers to God in times of hardship. Consequently this site has become a revered place of pilgrimage serving as both a temple and a sanctuary where people come to pray and seek comfort through Father Dieps spiritual presence.
As stated on its FY2025 Form 990.
Programs
ather Truong Buu Diep was born on January 1 1897 in An Giang Vietnam and ordained in 1924. Despite the dangers of war in 1945 he chose to remain with his parishioners declaring I live among my parishioners and I will die among them. On March 12 1946 he was captured and sacrificed his life to save over 70 members of Tac Say Parish. He was buried in the sacristy of Tac Say Church Bac Lieu Province. The Truong Buu Diep Foundation TBDF is a faith-based nonprofit established on August 16 2011 by John Nguyen and Holly Pham of Fountain Valley California in gratitude for blessings they attribute to Father Diep. TBDFs mission is to honor his legacy by 1 sharing testimonies of his intercession through media and 2 providing community service in his name. The foundation offers a space for prayer and reflection and hosts a monthly prayer session on the first Thursday to pray for intentions left by visitors.

$13,031 spent$213,910 earned by the program6% of program spendingDue to the COVID-19 pandemic our office was closed for nearly two years from the end of 2020 to the end of 2021. Following the reopening the number of visitors declined significantly creating challenges in sustaining our workforce in the post-pandemic period. However we tried to keep key staff to operate the daily tasks of TBDF.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $530k to $304k (−43%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.

Who funds it, year by year
2020 → 2023: the base narrowed from 2 funders to 1 funder, grant income fell $6k → $308.
2 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
TRUONG BUU DIEP FOUNDATION leans on a few funders — its largest provides 71% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund TRUONG BUU DIEP FOUNDATION.
Largest funder’s share by year: 2020 88% · 2021 100% · 2022 100% · 2023 100% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
100% of TRUONG BUU DIEP FOUNDATION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $8k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
