Who Is Santtu Seppälä?
Santtu Seppälä is a businessman and finance expert who is best known as the husband of actress Sarah Rafferty. While his wife has spent many years working in television and film, Santtu has built his own career in the world of investment management and business strategy. He has always preferred a quiet life instead of being in the public eye.
Although many people first hear his name because of Sarah Rafferty, Santtu has achieved plenty on his own. Over the years, he has worked for several well-known companies and held leadership positions in finance. His work has earned him respect in the business world long before many fans became interested in his personal life.
Another reason people find Santtu Seppälä interesting is his international background. Before starting his career, he lived in several different countries. Those experiences gave him a wider view of the world and helped him become comfortable working with people from many cultures.
Even today, Santtu keeps a low profile. He rarely gives interviews or seeks public attention. Instead, he focuses on his work and enjoys spending time with his wife and daughters. That quiet and steady lifestyle is one reason many people admire him.
Santtu Seppälä’s Early Life and Family
Santtu Seppälä comes from a Finnish family and spent much of his childhood connected to Finland. Some published sources give different details about his exact birthplace. While some say he was born in Finland, others report that he was born in Illinois in the United States to Finnish parents. What is clear is that his family has strong Finnish roots.
His father has been identified in some reports as Antti V. Seppälä, who worked as an independent consultant in the pharmaceutical industry. However, very little has been shared publicly about the rest of Santtu’s family, showing just how private they have chosen to remain.
One of the most interesting parts of Santtu’s childhood is that he did not grow up in just one place. Before going to college, he lived in six different countries. These included Finland, Sweden, Denmark, France, Germany, and the United States. Living in so many places gave him the chance to experience different cultures, languages, and ways of life.
Moving from one country to another can be difficult for many children, but it also teaches valuable life lessons. Santtu learned how to adapt to new places, meet new people, and see the world from different points of view. Those early experiences likely helped him later in his international business career.
Many reports also describe Santtu as having both Finnish and American ties. He has lived in the United States for many years, where he built his career, married Sarah Rafferty, and raised their family. His background reflects both his Finnish heritage and his life in America.
His Education and Love for Tennis
Education has always been an important part of Santtu Seppälä’s journey. After finishing school, he attended Yale University, one of the most respected universities in the United States. There, he worked hard in the classroom while also staying active in sports.
He graduated from Yale in 1993 with a bachelor’s degree. Some sources describe his studies as Ethics, Politics, and Economics, while others simply note that he earned a finance-related degree. No matter how it is described, his education gave him a strong base for a future in business and investment management.
College was not only about books and classes. Santtu was also a member of Yale’s Varsity Tennis Team. He competed at a high level and became an Ivy League champion. Playing college sports taught him discipline, teamwork, and the importance of staying focused under pressure.
After completing his studies at Yale, Santtu wanted to learn even more about business. He later attended The Wharton School at the University of Pennsylvania, one of the world’s best business schools. There, he earned his Master of Business Administration (MBA) in 1998.
Studying at both Yale and Wharton gave Santtu an excellent education. Along with his sports experience, it helped prepare him for leadership roles that he would later hold in the financial world.
Santtu Seppälä’s Business Career
After finishing college, Santtu Seppälä started building his career in finance. His first major job was at Salomon Brothers, where he worked as a financial analyst. This early role gave him valuable experience in banking and helped him understand how large financial companies operate.
After that, he spent about a year with the Finnish Defence Forces before returning to the business world. He later joined Lazard Asset Management, where he worked as an analyst for several years. During this time, he continued to learn about investments, financial planning, and managing money.
As his experience grew, Santtu moved into larger leadership roles. He became a Portfolio Manager at Cantillon Capital Management in New York. He also founded Kiitos Capital Management, where he served as Managing Member and Chief Investment Officer. These positions showed that he had become a trusted leader in investment management.
Santtu also worked with Staxxon, where he served as Chief Strategy Officer and became a member of the company’s management committee. His work focused on business growth, planning, and helping the company move forward with new ideas.
In 2021, Santtu joined the Angeleno Group, a private equity investment firm, as Vice President of Strategy and Business Development. In this role, he continues to use his many years of experience to help businesses grow and develop new opportunities. His career shows that success does not always happen in front of cameras. Sometimes it is built through years of steady work, smart decisions, and strong leadership.
How Santtu Seppälä Met Sarah Rafferty

Long before Sarah Rafferty became famous around the world for playing Donna Paulsen in Suits, she met someone who would become one of the most important people in her life. That person was Santtu Seppälä, and their story began while they were both students at Yale University.
At Yale, Sarah was studying acting while Santtu was focused on his education and preparing for a career in business. Even though they planned very different futures, they quickly formed a strong connection. Their relationship grew naturally during their college years, and they continued dating after graduation.
According to Sarah, the couple’s first photo together was taken in 1994. Years later, she shared that picture while celebrating Santtu’s birthday, calling it the first time they had been photographed as a couple. The old picture became a sweet reminder of where their journey together began.
Instead of rushing into marriage, Santtu and Sarah spent about seven years getting to know each other. They supported one another through school, career changes, and life’s many ups and downs. That strong foundation helped prepare them for a lasting marriage.
Their Marriage and Family Life
After dating for about seven years, Santtu Seppälä and Sarah Rafferty decided to get married. They tied the knot on June 23, 2001, at the Roman Catholic Church of St. Mary in Greenwich, Connecticut. Their wedding ceremony was led by Rev. Alfred Riendeau and was attended by family and close friends.
Since that special day, the couple has built a strong marriage that has lasted for more than two decades. In a world where many famous relationships do not last, their marriage has remained steady. They have continued to support each other through busy work schedules, family life, and many changes over the years.
Sarah often shares sweet messages for Santtu on social media during birthdays and anniversaries. In 2021, when they celebrated their 20th wedding anniversary, she posted a wedding photo and thanked him for the many happy years they had shared together. Her posts show how much she values their life together.
She has also shared old photos from the 1990s, including the couple’s first picture together. These memories give fans a small look into their long journey as a couple. Even after so many years, they still enjoy celebrating life’s special moments together.
One reason their marriage has remained strong is that they always work as a team. Sarah has often said that both of them support each other’s careers. Instead of trying to make everything perfect, they simply help each other whenever it is needed.
Santtu Seppälä and Sarah Rafferty’s Children
Santtu Seppälä and Sarah Rafferty are proud parents of two daughters. Their first daughter, Oona Gray Seppälä, was born on October 22, 2007. Their second daughter, Iris Friday Seppälä, was born in January 2012.
Even though Sarah is a well-known actress, both parents have worked hard to give their daughters a normal and private childhood. They do not often share personal family details, but from time to time Sarah posts sweet moments that show their close family bond.
When Sarah was filming Suits in Toronto, the family made an important choice. Rather than living apart, they moved together between Los Angeles and Toronto. Sarah once shared that their oldest daughter attended two different schools during that time. At first, she worried about the change, but it turned into a positive experience that helped build her daughter’s confidence.
Family time is very important in their home. Sarah has shared that one of their favorite Sunday traditions is enjoying Santtu’s homemade Finnish pancakes together. Simple family moments like these have helped keep their family close despite busy work lives.
Sarah also enjoys celebrating her daughters on social media. She has shared birthday messages, family photos, poems, and even fun projects like building a fairy house with Iris. These small moments show the loving and playful side of their family life.
How They Balance Work and Family
Many people wonder how two busy parents manage both work and family. Sarah Rafferty has shared that there is no perfect answer. She believes that trying to find perfect balance is not realistic. Instead, she and Santtu simply work together every day.
One of Sarah’s best-known comments is that “balance is an illusion.” She explained that she and Santtu take turns helping each other whenever one person becomes busier. That teamwork has allowed both of them to continue their careers while staying close to their children.
The years spent filming Suits were especially busy. Because much of the show was filmed in Toronto, the family often lived between Toronto and Los Angeles. Instead of letting work separate them, they chose to stay together as one family whenever possible.
Santtu has also played a big role in helping Sarah continue acting while being an involved mother. Sarah has openly thanked him many times, saying she could not have done it without his support. Their relationship shows that success is often built through teamwork rather than doing everything alone.
Even with full schedules, they still make time for each other. Sarah has shared that they enjoy hiking, doing hot yoga, and going out for dinner where they can simply sit, relax, and talk without interruptions. Those quiet moments help keep their relationship strong.
The End of the Story
Santtu Seppälä may be best known as Sarah Rafferty’s husband, but his own story is just as interesting. From growing up in several countries to earning degrees from Yale and Wharton, he has built a successful career through hard work, education, and smart planning.
