Daniel A. Jost is an American retired teacher best known as the father of comedian and Saturday Night Live star Colin Jost. Although his son has established a successful career in television and comedy, Daniel has built his own professional identity through education and community involvement. He worked at Staten Island Technical High School in New York and became publicly recognised for helping students during the September 11 attacks. He is also the husband of Dr. Kerry Kelly, a physician who served as the Chief Medical Officer of the New York City Fire Department (FDNY). Their family story includes education, public service and a long-standing connection to Staten Island. Exploring his background offers readers a better understanding of his parents, personal life, marriage, children and professional contributions beyond his famous family connection.
Who Are Daniel A. Jost’s Parents?
Information about Daniel’s biological parents is not sufficiently documented in reliable public sources. Their names, occupations, family history and personal backgrounds have not been consistently established. Although some online biography websites publish details about his childhood and parents, those claims should not automatically be treated as facts without dependable supporting records. Daniel has maintained considerable privacy, so there is no complete public account of his early family environment.
What is better documented is the family he established with his wife, Dr. Kerry Kelly. Together, they raised two sons, Colin and Casey, who later developed careers in the entertainment industry. The family has strong connections to Staten Island, where Daniel worked as a teacher and his sons grew up. This distinction is important when researching his biography: information about Colin’s parents and siblings is more widely available than details about Daniel’s own parents and earlier generations.
Daniel A. Jost’s Education and Academic Background
Daniel’s academic background attracts interest partly because of his connection to Brown University. He met his future wife, Kerry Kelly, while they were associated with the university. Their first meeting has become a memorable family story, which Colin has shared publicly. According to his account, Kerry needed a slide rule for an examination and asked Daniel to lend her one. This small interaction eventually became the beginning of their relationship.
Although the Brown connection is part of the family’s documented history, detailed information about Daniel’s degree, graduation date and complete academic qualifications is less clearly established in authoritative public records. Some online biographies also associate him with engineering studies at the Massachusetts Institute of Technology, but a specific qualification should not be presented as confirmed without stronger supporting documentation. It is equally important not to confuse his academic background with Colin’s education, as Colin attended Harvard University.
What Did Daniel A. Jost Do for a Living?
Daniel worked as a teacher at Staten Island Technical High School, a specialist public high school in New York City. His professional career centred on education and supporting students during their academic development. Although detailed information about his teaching subjects and exact employment dates is limited, his association with the school has been confirmed by the College of Staten Island. The institution identified him as a retired Staten Island Tech teacher when his son received an honorary doctorate in 2025.
His teaching career also involved responsibilities beyond the classroom. During the September 11 attacks, Daniel was at school when the news of the World Trade Center disaster reached students and staff. Many pupils had family members working in Manhattan or serving as first responders. He helped students leave school and reunite with their parents and guardians while providing reassurance during a frightening and uncertain day. This experience illustrates the important role educators can play in supporting young people during emergencies.
Who Is Daniel A. Jost’s Wife, Dr. Kerry Kelly?
Daniel’s wife is Dr. Kerry Kelly, an American physician who spent 37 years working with the New York City Fire Department. She became the FDNY’s first female Chief Medical Officer and held the position for the final 24 years of her department career. Her responsibilities involved overseeing medical professionals and supporting the health needs of firefighters and other emergency personnel. Her work was particularly important because firefighters face occupational risks that require regular medical monitoring and specialist care.
Dr. Kelly’s contribution became especially significant during and after the September 11 attacks. On that day, she travelled to the World Trade Center to provide medical assistance to injured civilians and emergency responders. She helped establish medical triage facilities and later focused on the health consequences experienced by firefighters exposed to dangerous substances during rescue and recovery operations. Daniel’s account of that day, shared alongside his wife’s through the 9/11 Memorial & Museum, provides insight into how their professional responsibilities affected their family.
How Many Children Does Daniel A. Jost Have?
Daniel and Dr. Kerry Kelly have two sons, Colin Jost and Casey Jost. Both grew up in Staten Island and eventually developed careers in entertainment, although they followed different professional paths. Colin became a comedian, actor and television writer, while Casey established himself as a writer and producer. Their professional achievements have brought public attention to their parents, but Daniel and Kerry have maintained their own identities outside the entertainment industry.
The brothers also have separate family lives. Colin is married to actress Scarlett Johansson, and they have children together. Casey is married to Lisa Kleinman, and they have a daughter. These relationships make Daniel and Kerry grandparents as well as the parents of two recognised entertainment professionals. Despite their sons’ public profiles, the family generally keeps personal matters private, and Daniel’s biography is best understood through his own professional background rather than details of his children’s celebrity lives.
What Is Daniel A. Jost’s Relationship With Colin Jost?
Colin Jost is Daniel’s best-known son and the main reason many readers search for information about his family. Colin joined the writing team of Saturday Night Live in 2005 and later became a co-anchor of the programme’s Weekend Update segment in 2014. His career has included comedy writing, acting, television appearances and publishing. His success has made him one of the familiar faces associated with American late-night entertainment.
Daniel’s professional background in education provides an interesting contrast to Colin’s career in comedy. While Colin works in television and entertainment, his father spent years teaching students and participating in community activities. Colin has occasionally shared stories about his parents, including how they met and how their family experienced September 11. These accounts offer a glimpse into his upbringing without suggesting that Daniel was directly involved in managing his son’s entertainment career.
Daniel A. Jost’s Role at the Staten Island Museum
Community involvement is another significant part of Daniel’s public life. He served as chair of the Staten Island Museum’s board from 2019 to 2023, helping guide the organisation through an important period that included the challenges of the COVID-19 pandemic. The museum preserves the cultural, historical and natural heritage of Staten Island, making its work valuable to local residents, researchers and visitors. Daniel’s leadership demonstrated an interest in supporting an institution focused on education and community history.
One of his notable contributions was arranging a comedy benefit show in September 2019 featuring Colin Jost, Casey Jost, Michael Che and other performers. The event raised $50,000 for the museum. He also helped bring an Impractical Jokers exhibition to the institution. These achievements provide specific examples of his community involvement and show how he helped use local entertainment connections to support a cultural organisation. His museum work is an important part of his biography rather than simply an extension of his sons’ careers.
Daniel A. Jost’s Net Worth and Family Wealth
Daniel’s personal net worth has not been reliably established through public financial records or verified disclosures. Some celebrity biography websites may publish estimated figures, but there is insufficient dependable information to confirm a specific amount. His former teaching career and community involvement are publicly documented, yet they do not reveal his savings, retirement arrangements, property ownership or investments. Giving him a precise net worth would therefore create a misleading impression of financial certainty.
Questions about the family’s wealth also arise because Colin has achieved considerable success in television and comedy. However, his professional earnings should be considered separately from his parents’ finances. Daniel and Kerry both built established careers in education and medicine, but their professional achievements do not establish the family’s overall wealth. The most accurate description is that they have professional backgrounds and a history of community involvement, while their private financial circumstances remain undisclosed.
