When people search for Pedro Pascal’s family, they often become curious about the man who was his father. José Balmaceda Riera was not an actor or a celebrity, but he had an interesting professional life of his own. He was a Chilean doctor who built his career around reproductive medicine and later became connected to a major controversy involving fertility treatment in California.
José’s story is also linked to the early years of Pedro Pascal’s life. The family left Chile when Pedro was still very young and eventually built a life in the United States. While Pedro went on to become a well-known actor through projects such as Game of Thrones, The Mandalorian, and The Last of Us, his father remained largely outside the entertainment world.

Who Is José Balmaceda Riera?
José Balmaceda Riera is a Chilean physician and reproductive endocrinologist who spent much of his professional life working in fertility medicine. He trained in obstetrics and gynecology and later developed a particular interest in reproductive health and infertility treatment. His medical career took him from Chile to the United States, where he became involved with fertility research and treatment.
His name is now familiar to many people because of his connection to Pedro Pascal. However, his medical career existed long before Pedro became famous. José worked during a period when assisted reproductive technology was developing quickly, making his professional field both promising and highly sensitive.

José Balmaceda Riera Age and Early Years
Public information about José Balmaceda Riera’s childhood is limited, but sources generally place his birth in 1948 in Santiago, Chile. Some online biographies provide August 22, 1948, as his full date of birth, although that exact date is not as strongly supported by major historical reporting. If the reported birth year is correct, he is 78 years old in 2026.
A contemporary profile described him as the son of a timber-mill owner and noted that he grew up with five sisters. His early years were spent in Chile before his education and medical career eventually took him abroad. Unlike his son, José has rarely discussed his private childhood in detail, so many parts of his early life remain unknown.
His Medical Education and Career
José began his medical education in Chile at the Pontifical Catholic University of Chile. He later traveled to the United States for further training and became a Rockefeller Fellow in reproductive biology at the University of Texas Health Science Center. He also completed medical training in obstetrics and gynecology before moving deeper into reproductive endocrinology.
His career developed at a time when doctors were exploring new ways to help people struggling with infertility. José became involved in advanced fertility procedures and worked with other specialists, including Ricardo Asch and Sergio Stone. His professional work eventually brought him to the University of California, Irvine, where he became associated with its reproductive health program.
His Work in Fertility Medicine
José’s medical specialty was focused on reproductive endocrinology and infertility. He worked in an area that involved helping patients who were unable to conceive naturally, and he became associated with developing fertility techniques that were receiving attention at the time.
One procedure connected with his work was gamete intrafallopian transfer, commonly called GIFT. The technique involved placing eggs and sperm into a woman’s fallopian tube in an attempt to allow fertilization to occur inside the body. His work with fertility treatment helped establish his professional reputation before the later controversy changed the direction of his career.
What Happened at the UCI Fertility Program?
The most controversial period of José Balmaceda Riera’s career began in 1995. Serious allegations were raised concerning fertility treatment at the University of California, Irvine. The university said that some eggs and embryos may have been handled or transferred without the proper consent of patients.
The allegations were serious because reproductive material is deeply personal and involves both medical and family decisions. Patients expected their eggs and embryos to be used only according to agreements they had made with their doctors. José denied knowingly engaging in improper conduct, and the case continued through investigations and legal proceedings.
The Egg and Embryo Controversy
The controversy surrounding the UCI program focused partly on claims that eggs or embryos from some fertility patients had been transferred to other patients without proper authorization. Investigators examined patient records and tried to determine how many people might have been affected.
It is important to understand that reports about potentially affected patients did not necessarily mean that every person had experienced an unauthorized transfer. The investigation involved different claims, different patients, and different stages of review. Because of this, the case should not be reduced to the simple claim that José was convicted of stealing embryos.

Did José Balmaceda Riera Face Criminal Charges?
José did face federal legal proceedings in the United States. In 1997, a federal grand jury indicted him along with Ricardo Asch and Sergio Stone on income-tax-evasion charges. Prosecutors alleged that the doctors had failed to report certain income correctly and had submitted false tax information.
Earlier, José had also faced mail-fraud charges connected with the wider fertility-clinic investigation. These legal matters are sometimes mixed together in online articles, which can make the story difficult to understand. The safest description is that he was involved in a major medical controversy and later faced federal fraud and tax-related charges.
Why Did He Leave the United States?
José eventually returned to Chile while the investigations were continuing. Contemporary reports said he left California and went back to his home country as legal problems surrounding the fertility program developed. His departure became an important part of the story because U.S. authorities continued pursuing the case after he had left.
In 2001, reports said that José was arrested at an airport in Buenos Aires, Argentina, after authorities recognized him as a fugitive. The arrest brought renewed attention to a case that had started several years earlier. His legal history therefore extended well beyond the original 1995 controversy.
José Balmaceda Riera’s Wife and Family
José was married to Verónica Pascal Ureta, a Chilean child psychologist. Together, they had four children: Javiera Balmaceda, Pedro Pascal, Nicolás Balmaceda Pascal, and Lux Pascal. The family left Chile during the political unrest of the 1970s and eventually established a new life outside the country.
Their children later followed different paths. Javiera became involved in the entertainment industry, Nicolás pursued medicine and neuroscience, Pedro became an internationally recognized actor, and Lux developed a career in acting. The family’s Chilean roots have remained an important part of their shared story.
José Balmaceda Riera and Pedro Pascal
The public interest in José is largely connected to Pedro Pascal. Born in Santiago in 1975, Pedro grew up between different countries after his family left Chile. He later built a successful acting career, gaining major attention through Game of Thrones, Narcos, The Mandalorian, and The Last of Us.
Pedro was born with the name José Pedro Balmaceda Pascal but became known professionally as Pedro Pascal. His mother’s surname eventually became the name recognized by audiences around the world. While Pedro has become the more famous member of the family, his father’s medical career remains an important part of his family background.
José Balmaceda Riera Nationality and Later Life
José Balmaceda Riera is Chilean, and after returning from the United States, he continued his connection with medicine in Chile. A Chilean fertility center has listed him as part of its medical team and describes his experience in reproductive medicine.
His life today is much less public than that of his son. There are occasional reports about him in connection with Pedro and the family, but detailed information about his daily life is limited. Claims about his current income, exact lifestyle, or retirement status should therefore not be treated as confirmed unless supported by a reliable source.
What Is José Balmaceda Riera’s Net Worth?
There is no trustworthy public figure for José Balmaceda Riera’s net worth. Various websites may publish estimates, but there is no strong financial documentation that confirms a particular amount.
His long career as a doctor and fertility specialist likely provided professional income, but personal wealth cannot be calculated from a medical career alone. For that reason, the most accurate statement is that his net worth has not been publicly confirmed.

His career at the University of California, Irvine placed him at the center of important developments in fertility medicine, but the 1995 controversy surrounding the clinic changed his professional and legal story.
