Who Is Nathan Andersen?
Nathan Andersen is an American entrepreneur and fashion designer. He is best recognized as the longtime husband of Criminal Minds actress A. J. Cook, whom he met during college.
Away from his connection to Hollywood, Nathan has developed his own professional identity. His interests include business, clothing design, travel, outdoor activities, creativity, and spending quality time with his family.
Nathan prefers a quieter lifestyle than many people connected with the entertainment industry. Instead of pursuing celebrity attention, he has concentrated on entrepreneurship, family life, and projects that match his interests.
Early Life and Childhood
Nathan Andersen was born on May 25, 1978, in the United States. He spent part of his early life in an environment where adventure, creativity, sports, and outdoor activities were important.
Growing up, Nathan developed an adventurous personality. Exploring different places, climbing, collecting things, and enjoying nature became part of his childhood and helped shape many of his later interests.
His family environment also influenced his outlook on life. Exposure to athletic and creative people encouraged him to remain active, curious, and willing to explore different opportunities as he grew older.
Education and Interest in Film
Nathan continued his education at Utah Valley University. He studied film, giving him an opportunity to learn about visual creativity, storytelling, entertainment, and the different ideas involved in producing creative work.
His college years became important for another reason. Nathan met A. J. Cook while they were students, and the two attended the same film class before eventually developing a romantic relationship.
Although Nathan later moved away from pursuing entertainment professionally, his creative background remained useful. His interests eventually took him toward entrepreneurship, design, and building projects that better suited his personality.
How Nathan Andersen Met A. J. Cook
Nathan Andersen and A. J. Cook met long before Cook became widely recognized for Criminal Minds. Their first connection developed while both were attending Utah Valley University and studying within the film environment.
Their relationship began naturally during their student years. Friendship gradually developed into romance, allowing them to build their relationship before Hollywood fame became a major part of their everyday lives.
That early connection became the foundation of a lasting partnership. Nathan remained beside Cook as her acting career developed, while he eventually chose a professional direction outside mainstream entertainment.
Marriage to A. J. Cook
Nathan Andersen married A. J. Cook on August 3, 2001. Their marriage has continued for more than two decades, covering major changes in their careers, family, and personal lives.
Cook developed a successful acting career and became particularly famous through Criminal Minds. Nathan, meanwhile, maintained a lower public profile and focused more heavily on business, creativity, and their family.
Their relationship also includes a playful side. Family moments and humorous exchanges shared online have shown a couple who remain comfortable together despite their long connection with the entertainment world.
Who Is A. J. Cook?
A. J. Cook is an actress best known for playing Jennifer “JJ” Jareau in Criminal Minds. Her long-running role on the crime drama made her recognizable to television audiences.
Behind her professional success, Nathan has remained an important part of her personal life. Their relationship began before Cook achieved the level of television recognition she later experienced.
The couple has managed different professional paths while building their family together. Cook works primarily within entertainment, while Nathan has developed interests and businesses outside the traditional Hollywood career structure.
Nathan Andersen’s Career
Nathan Andersen initially explored opportunities connected with entertainment after completing his studies. His education in film provided a natural starting point, but he eventually realized that Hollywood was not his preferred career environment.
Rather than continuing along that path simply because of his connection with entertainment, Nathan changed direction. He became involved with a startup business alongside a friend and spent several years gaining practical experience.
That period helped him develop knowledge about entrepreneurship and business operations. His professional journey eventually led toward creating something more personal that combined his creative instincts with his interest in travel and adventure.
Why Nathan Andersen Left the Hollywood Path
Nathan had studied film and was close to the entertainment industry through his wife. However, being surrounded by Hollywood did not mean that becoming a public entertainment personality was right for him.
He preferred a lifestyle with greater independence and less attention. Moving toward business allowed him to use his creativity without needing to build a career based primarily on public recognition.
This decision became an important part of Nathan’s professional identity. Instead of following his wife into acting, he created a separate career that reflected his own interests and preferred way of living.
Walter Sky Clothing Brand
In 2018, Nathan Andersen moved further into entrepreneurship by starting Walter Sky with his brother, Wesley Andersen. The clothing project combined business with Nathan’s interests in adventure, travel, and practical design.
Walter Sky was created around clothing that could fit different environments. Rather than concentrating only on changing fashion trends, the concept emphasized simple pieces designed around usefulness, comfort, and versatility.
The brand reflects many of Nathan’s personal interests. Travel, outdoor environments, clean design, and uncomplicated living all connect naturally with the image and philosophy surrounding his clothing business.
Nathan Andersen’s Approach to Fashion
Nathan’s approach to clothing is closely connected with how he lives. He values practical products that can remain useful whether someone is exploring a city, traveling, or spending time outdoors.
His fashion interests are therefore different from highly glamorous celebrity clothing. Simplicity and functionality play an important role, with clothing intended to suit people interested in movement and adventure.
Walter Sky also gave Nathan a way to combine creativity with entrepreneurship. Instead of working directly within film, he could use creative thinking while controlling the direction of his own business project.
Nathan Andersen’s Family Life
Family is an important part of Nathan Andersen’s everyday life. Despite being married to a recognizable television actress, he has maintained a home life that is relatively separate from constant celebrity attention.
Nathan and A. J. Cook balance different careers while supporting their household together. Cook works in acting, while Nathan divides his attention between business interests, family responsibilities, and personal activities.
The family lives in Los Angeles, California. Although Los Angeles places them close to the entertainment industry, Nathan continues to value outdoor experiences, travel, privacy, and time spent with those closest to him.
Nathan Andersen’s Children
Nathan Andersen and A. J. Cook are parents to two sons. Their older son, Mekhai Allan Andersen, was born in 2008, while their younger son, Phoenix Sky Andersen, arrived in 2015.
Fatherhood is an important part of Nathan’s life. Family outings, travel, playful moments, and everyday activities have allowed him to enjoy parenting while remaining involved in his sons’ lives.
His children also have an interesting connection with their mother’s television career. Both boys have appeared in Criminal Minds, bringing a small part of Nathan and Cook’s real family into the series.
His Sons’ Criminal Minds Appearances
Mekhai Andersen appeared in Criminal Minds as Henry, the son of A. J. Cook’s character, JJ. This created an unusual connection between Cook’s real family and her fictional television family.
Phoenix Andersen also became involved with the series. He appeared as baby Michael, meaning both of Nathan and Cook’s sons had opportunities to participate in their mother’s best-known television project.
Nathan himself did not pursue a role on Criminal Minds. His professional interests remained outside acting, while his wife and children developed this memorable family connection with the popular television series.
Nathan Andersen as a Father
Nathan’s approach to fatherhood appears relaxed and playful. He enjoys sharing humorous family moments while also giving his children opportunities to experience travel, nature, and ordinary activities away from entertainment industry events.
One example of his humor came when he shared an image of his son washing a vehicle. Nathan jokingly described the moment as “Child labor #carwashforcandy,” turning an ordinary activity into a funny parenting moment.
These small experiences reflect the family-focused side of Nathan’s personality. Despite his wife’s successful acting career, ordinary time with his children remains an important part of his lifestyle.
Nathan Andersen’s Thyroid Cancer Journey
Nathan Andersen faced a major personal challenge when he dealt with thyroid cancer around 2019. The experience introduced a much more serious chapter into an otherwise private and family-centered life.
Nathan did not make his illness the center of his public identity. However, he eventually shared an image showing the scar on his neck and revealed positive news about becoming cancer-free.
A. J. Cook strongly supported her husband during the experience. Her memorable statement that “Cancer picked the wrong guy to mess with” reflected the strength and encouragement surrounding Nathan during his health journey.
Life After Cancer
Becoming cancer-free represented an important personal victory for Nathan. His experience demonstrated another side of his personality beyond entrepreneurship, travel, fashion, and his relationship with a famous actress.
After facing the illness, Nathan continued concentrating on his family and personal interests. His lifestyle remained centered around meaningful experiences rather than turning his health story into a source of celebrity attention.
His journey also connected with people who had experienced similar health challenges. Nathan’s scar became a visible reminder of a difficult period that he successfully moved beyond.
Nathan Andersen’s Personality and Interests
Nathan Andersen appears most comfortable with an active but uncomplicated lifestyle. Nature, outdoor adventures, travel, creativity, and family experiences are recurring interests throughout different parts of his personal journey.
He is also notably different from the traditional image of a Hollywood spouse. Rather than constantly appearing at the center of celebrity culture, Nathan has created an identity built around his own priorities.
Creativity remains another important characteristic. From studying film to developing a clothing business, Nathan has repeatedly chosen activities where ideas, design, and personal expression can play meaningful roles.

Nathan has used the Instagram handle @nathanandy to share parts of his personal world. His posts provide glimpses of family experiences, outdoor adventures, travel, humor, and other everyday moments.
His online presence matches his personality. Instead of presenting an extremely polished celebrity lifestyle, Nathan’s content has focused more naturally on experiences, relationships, and activities that interest him.
Walter Sky also has an online presence through @waltersky.co. Through the brand account, Nathan’s interest in clean design, practical clothing, travel, and adventure becomes closely connected with his professional work.
Nathan Andersen’s Net Worth

His lifestyle, however, is not defined mainly by expensive possessions or public displays of wealth. Nathan places greater emphasis on his family, creative work, travel, nature, and personal experiences.
This makes his public image noticeably different from many personalities associated with Hollywood. Business success is part of his story, but it does not appear to be the only measure of the life he has built.
