Dag Heggelund, devoted husband, father, grandfather, and brother, passed away peacefully on October 24, 2025, at the age of 62. Born on November 17, 1962, in Andenes, Norway, Dag was the youngest of four children born to Asta and Rolf Heggelund.

Dag's journey carried him far beyond his hometown on the northern coast of Norway. In 1982, he moved to Texas to study at Texas A&M University, where he earned his bachelor's, master's, and PhD degrees in Petroleum Engineering and Mathematics. It was there, in 1984, that he met the love of his life, Teri, whom he married in 1987.

A brilliant engineer, software developer, and entrepreneur, Dag founded four companies and launched multiple flagship products that revolutionized their respective industries. His pioneering work in Data Quality Management, Continuous Monitoring, and Continuous Auditing made lasting contributions to the oil and gas sector and to food traceability systems worldwide.

Beyond his professional achievements, Dag was a man of deep passions and boundless curiosity. He loved traveling to Norway with his family, sharing with his sons the beauty and traditions of his homeland. Some of his happiest days were spent outdoors in the Norwegian wilderness-fishing in quiet fjords, hiking along rugged trails, and reconnecting with the place that shaped him.

At home in Texas, Dag was known for his love of barbequing and his legendary brisket, which he perfected over the years and took great pride in sharing with friends and family. He cherished hosting gatherings filled with laughter, good food, and stories, embodying the warmth and hospitality that defined his life.

Dag was preceded in death by his parents, Asta and Rolf Heggelund. He is survived by his beloved wife of 38 years, Teri Heggelund; his children, John Heggelund, Philip Heggelund, and Christy Hopkins; his grandchildren, Arthur Heggelund and Margot Heggelund; his brother, Per Heggelund; and his sisters, Ingrid Heggelund and Dagny Kristoffersen.

Dag will be remembered for his brilliant mind, generous heart, and enduring love for family and friends. He is gone but not forgotten-his spirit and his stories will live on in all who were fortunate to know and love him.

Dag Heggelund, trofast ektemann, far, bestefar og bror, sovnet fredelig inn den 24. oktober 2025, i en alder av 62 år. Dag ble født 17. november 1962 på Andenes i Norge, som den yngste av fire barn i familien til Asta og Rolf Heggelund.

Dags livsreise tok han langt fra hjemstedet på Nord-Norges kyst. I 1982 flyttet han til Texas for å studere ved universitetet Texas A&M, hvor han tok bachelor, master og doktorgrad i petroleumsteknikk og matematikk. Det var der, i 1984, han møtte sitt livs kjærlighet, Teri, som han giftet seg med i 1987.

En fremragende ingeniør, programvareutvikler og gründer, Dag grunnla fire selskaper og lanserte flere banebrytende produkter som revolusjonerte sine respektive bransjer. Hans pionerarbeid innen datakvalitetsstyring, kontinuerlig overvåkning og modifisering har satt varige spor både i olje- og gassindustrien, samt i globale systemer for sporbarhet av mat.

Men Dag var så mye mer enn bare jobben sin. Han var en mann med dype lidenskaper og grenseløs nysgjerrighet. Han elsket å reise til Norge med familien sin, og dele skjønnheten og tradisjonene i hjemlandet sitt med sønnene sine. Noen av hans aller beste stunder var ute i norsk natur – fiske i stille fjorder, fotturer langs ulendte stier hvor han gjenopprettet forbindelsen til landet som formet han.

Hjemme i Texas var Dag kjent for at han elsket grilling, -spesielt hans legendariske brisket, som han perfeksjonerte gjennom mange år og stolt delte med venner og familie. Han satte stor pris på å være vertskap for sammenkomster fylt med latter, god mat og historier, og utstrålte varmen og gjestfriheten som karakteriserte livet hans.

Dag ble forutgått i døden av sine foreldre, Asta og Rolf Heggelund. Han etterlater seg sin kjære kone gjennom 38 år, Teri Heggelund; barna John Heggelund, Philip Heggelund og Christy Hopkins; barnebarna Arthur Heggelund og Margot Heggelund; broren Per Heggelund; og søstrene Ingrid Heggelund og Dagny Kristoffersen.

Dag vil bli husket for sitt kloke hode, sitt store hjerte og sin dype kjærlighet til familie og venner. Han er borte, men vil aldri bli glemt – hans ånd og historier vil leve videre i alle som var så heldige å kjenne og være glad ham.
