Early Career
Marcel Siem was born in Mettmann, Germany, and started golf at a young age thanks to his golf-club-owning parents in Cologne. He played his first round with a putter at age two and practiced more seriously from age six.
Siem’s junior prowess earned him a win at the 1999 Sherry Cup and several German team appearances in amateur events. By 2000, he turned pro, determined to carve out a place for himself in Europe’s elite.
Over the next few years, Siem honed his skills on the European Tour, joining officially after successfully qualifying in 2002. His first professional breakthrough came with the Dunhill Championship win in 2004, setting the tone for a career defined by hard work and resilience.
Professional Career
Siem’s professional journey features six European Tour victories and a World Cup team win with Bernhard Langer in 2006. After his initial tour victory, Siem waited until 2012 for another breakthrough win at the Alstom Open de France, a result that propelled him to his first Open Championship.
In 2013, Siem won the Trophée Hassan II and narrowly missed out on a Masters slot, finishing 51st in world rankings.
2014 brought another European title at the BMW Masters, secured in a sudden-death playoff, and a high finish in the Race to Dubai.
In 2021, after a brief drop to the Challenge Tour, Siem bounced back with a Le Vaudreuil Golf Challenge win, and again in 2023 at the Hero Indian Open after relocating to Mauritius.
His consistency and flair for comebacks are legendary—most recently, he captured the 2024 Italian Open. These wins highlighted his determination and marked over 550 DP World Tour appearances.
Caddie
Marcel Siem works with Wian Verster as his caddie. Verster has stood by Siem’s side, including during the Italian Open win where their teamwork overcame a heated club selection debate.
The duo’s mutual understanding helps them prevail under pressure, and Verster’s reliability through Siem’s recent comeback from surgery has kept their partnership strong through the biggest tournaments.
Wife
Marcel Siem has been married to his wife, Laura Siem, since 2012. Laura is German and celebrates her birthday on May 25.
The couple has two daughters, Viktoria and Carlotta. Laura prefers to keep much of her private life away from the spotlight, but she has often been seen supporting Marcel at various golf tournaments. She has even assisted as his caddie during important events.
Beyond her supportive role in Marcel’s professional life, Laura has faced significant challenges, including a battle with cancer. During her treatment, she encouraged Marcel to keep playing and pursuing his career while she focused on her recovery.
