Daniel A. Jost is best known as the father of comedian and Saturday Night Live writer and performer Colin Jost. While his son became a familiar face on American television, Daniel built his own career away from the entertainment industry, working as a teacher on Staten Island and becoming involved with the Staten Island Museum. Colin himself has said that his father taught at Staten Island Technical High School and that many people on Staten Island knew one or both of his parents through their professional work.
Daniel’s public story also includes an important connection to September 11, 2001. He was teaching on Staten Island that morning while his wife, Dr. Kerry Kelly, was serving as the FDNY’s Chief Medical Officer and responding to the World Trade Center. Their firsthand account was later preserved by the National September 11 Memorial & Museum.
Because Daniel has kept much of his personal life private, some details frequently repeated online cannot be independently confirmed. The most useful way to understand his life is to focus on the parts supported by public records: his teaching career, his family, his experience during 9/11 and his years of service with the Staten Island Museum.
Who Is Daniel A. Jost?
Daniel A. Jost is an American educator and Staten Island community figure. He is the husband of Dr. Kerry Kelly and the father of Colin Jost and Casey Jost. Colin became widely known through Saturday Night Live, while Casey has also built a career as a writer and producer in comedy and television.
Unlike his sons, Daniel did not build his public profile through entertainment. His career was closely connected to education, and his long association with Staten Island gave him a strong local connection.
That background is important because it explains why Daniel sometimes appears in discussions about Colin Jost’s upbringing. He was not a celebrity when his children were growing up. He was a teacher whose work placed him in daily contact with families and students in the community.
A Career Centered on Teaching
One of the clearest facts about Daniel Jost is his work as a teacher at Staten Island Technical High School. Colin Jost has personally discussed his father’s occupation, explaining that his father taught at Staten Island Tech and that many people around Staten Island knew him through the school.
That detail also helps explain the family’s local reputation. Colin has described a childhood in which his mother was known as a doctor and his father was known as a teacher, making the family familiar to many people in the area even before Colin entered the entertainment business.
Public information about Daniel’s earlier professional life and exact educational history is much less consistent. A number of biography websites publish specific claims about his schooling and qualifications, but those details are not as well documented in primary sources as his teaching career. A careful biography should therefore avoid presenting uncertain information as established fact.
Daniel A. Jost and His Family
Daniel’s family includes his wife, Dr. Kerry Kelly, and their two sons, Colin and Casey.
Kerry Kelly had a long medical career and served as Chief Medical Officer of the New York City Fire Department. The National September 11 Memorial & Museum identifies her as the FDNY’s Chief Medical Officer on 9/11 and records her work establishing a medical triage centre and addressing the protection of rescue and recovery workers.
Daniel and Kerry’s professional lives were very different, yet both were closely tied to public service. Daniel worked with students in a school, while Kerry worked within New York City’s emergency medical system. Their family therefore grew up around two demanding professions based on responsibility and service.
Their sons later followed very different paths. Colin entered comedy and television, while Casey developed his own career behind the scenes in entertainment.
Where Colin Jost’s Childhood Fits Into the Story
Colin Jost was born in New York City in 1982 and was raised on Staten Island. His father’s work as a teacher and his mother’s medical career were part of the environment in which he grew up.
Colin has occasionally talked about his parents in interviews, often in a humorous way. Those comments provide a useful glimpse into the family without suggesting that Daniel actively sought fame.
The relationship between father and son has also appeared in public through charity events and other occasions. Photographs from public events have shown Daniel alongside Colin and other members of the family, reinforcing the fact that Daniel has supported his sons while maintaining a much quieter public presence.
Daniel Jost’s Experience on September 11
September 11, 2001, is one of the most significant documented moments in Daniel Jost’s life.
The National September 11 Memorial & Museum records that Daniel was a Staten Island school teacher on 9/11 and had many students whose parents were first responders. As the attacks unfolded, he was responsible for helping students deal with an extraordinary and frightening situation.
At the same time, Daniel’s wife was responding to the disaster in her role with the FDNY. The family’s experience therefore became personal as well as professional.
The memorial later filmed Daniel and Kerry sharing their memories for an educational programme. Their story was presented as a firsthand account intended to help students understand what happened on September 11 through the experiences of people who were directly affected.
This part of Daniel’s biography deserves attention because it demonstrates the two sides of his life at once. He was trying to help students at a moment of national crisis while also dealing with uncertainty surrounding his own family.
His Connection With the Staten Island Museum
Daniel Jost has also played a significant role in the Staten Island Museum, one of the area’s longstanding cultural institutions.
Museum records show that he served as Board Chair from 2019 to 2023. The organisation later thanked him for his leadership, particularly during the difficult period of the COVID-19 pandemic.
His involvement went beyond holding a title. The museum credited Daniel with arranging a 2019 comedy benefit featuring Colin Jost, Casey Jost and Michael Che. According to the museum, the event raised $50,000 for the institution. He was also credited with helping bring an Impractical Jokers exhibition to the museum.
His role has changed since then. In 2023, the museum identified Daniel as its board chair, while later museum materials listed him as Immediate Past Chair. The museum’s current trustee listing places Daniel Jost among its trustees, showing that his involvement with the institution has continued after his term as chair.
A Family With Strong Staten Island Roots
The Jost family’s connection to Staten Island is an important thread running through Daniel’s public biography.
Daniel worked at a local high school. Kerry served New York through her medical career. Colin grew up on Staten Island before becoming a nationally recognised comedian, and Casey also developed his own career in entertainment.
That local connection also appears in Daniel’s museum work. His community involvement was not simply connected to his son’s fame; it was part of a broader relationship with Staten Island institutions.
The result is a family story that crosses several areas—education, medicine, community organisations and entertainment—without requiring Daniel himself to become a public celebrity.
What Is Known About Daniel Jost Today?
As of 2026, the Staten Island Museum lists Daniel Jost as a trustee. This is the clearest current public indication of his ongoing institutional involvement.
Beyond that role, Daniel’s current day-to-day activities are not extensively documented in authoritative public sources. That limited visibility is worth acknowledging, especially because many celebrity-focused websites publish detailed claims about private individuals without identifying where the information came from.
There is also no reliable public financial record that establishes a confirmed figure for Daniel Jost’s net worth. Online estimates should therefore not be treated as verified facts.
The same caution applies to exact details about his age, private finances and other personal matters that are not clearly established by trustworthy sources.
Why Daniel A. Jost Continues to Attract Interest
Most people discover Daniel Jost while searching for information about Colin Jost. That makes sense: the relationship to a Saturday Night Live star is the most visible part of Daniel’s public identity.
But there is more to the story. Daniel spent years working in education, remained connected to Staten Island, experienced 9/11 from the perspective of a teacher and a family member of an FDNY medical leader, and later served in leadership at a local museum.
His biography is therefore less about celebrity and more about the life surrounding it.
The available evidence paints a picture of someone whose public contribution is rooted in education and community involvement. His connection to famous children explains why people search for him, but it does not fully define the life documented in public records.
Daniel A. Jost’s Public Legacy
Daniel Jost’s public legacy is closely tied to three areas: education, family and community service.
His teaching career gave him a direct role in the lives of Staten Island students. His family connected him to two sons who later entered the entertainment industry. And his work with the Staten Island Museum gave him an opportunity to contribute to a local cultural organisation over many years.
The 9/11 chapter adds another layer to that story. His firsthand experience was preserved not because he was famous, but because his perspective as a teacher and family member offered historical value.
For readers trying to separate fact from online speculation, these documented parts of his life provide a clearer and more useful biography than unsupported figures or dramatic claims.
Conclusion
Daniel A. Jost is more than the father of Saturday Night Live star Colin Jost. His own public history includes a long career as a Staten Island teacher, a family life shared with physician Dr. Kerry Kelly, an extraordinary experience during the September 11 attacks and years of involvement with the Staten Island Museum.
His sons’ success naturally brought additional attention to the family, but Daniel’s story developed independently through education and community work. In 2026, he remains listed as a trustee of the Staten Island Museum, continuing a connection that has lasted through several stages of his life.
Because some biographical details circulating online are difficult to verify, the most responsible account is one that stays close to documented facts. That approach makes Daniel A. Jost’s story both more accurate and more meaningful.
