Michael Greller has built a reputation as one of the most successful caddies on the PGA Tour. Known as the man behind Jordan Spieth’s bag, Greller has turned a career move that once looked risky into a story of success, loyalty, and consistency. As of 2025, his estimated net worth is above $10 million, making him one of the wealthiest caddies in golf. His story shows how determination and trust can transform a former math teacher into an essential figure in the professional golf world.
From Classroom to PGA Tour Fairways
Before golf became his full-time profession, Greller lived a very different life. He worked as a high school math teacher in Seattle, dedicating his time to education while spending free hours around golf courses. In 2010, he carried the bag for Justin Thomas at the US Amateur, and a year later, Jordan Spieth asked him to caddie at the US Junior Amateur. That simple opportunity became the turning point.
By 2013, Spieth was ready to turn professional, and Greller faced a decision. He gave up his teaching career and committed to life on tour, a move that would soon bring worldwide travel, major championship pressure, and financial rewards that far exceeded what he could earn in the classroom.
Caddie Earnings and Net Worth
Caddie pay is structured differently than most professions. Rather than a set salary, caddies receive a base fee each week plus a percentage of their golfer’s prize money. The standard breakdown is 10 percent for a win, 7 percent for a top 10 finish, and around 5 percent when the player makes the cut.
For Greller, Spieth’s success has been the foundation of his financial growth. Since their partnership began, he has earned well over $5 million directly from Spieth’s winnings. Some seasons saw Greller’s income climb past $1.5 million, an amount higher than many players on the Tour. By 2025, estimates place his total net worth at more than $10 million, thanks not only to Tour earnings but also to endorsements and smart financial planning.
Highlights on Tour
Michael Greller’s impact goes beyond numbers. He has often been Spieth’s steady voice during the most intense situations. A famous example came during the 2017 Open Championship at Royal Birkdale. After Spieth’s errant tee shot on the 13th hole, it was Greller’s calm guidance and strategic advice that helped Spieth escape with just a bogey. Spieth rallied to win the tournament, and that moment highlighted the value of a trusted caddie.
Since teaming up, Spieth and Greller have celebrated three major championships and multiple tournament victories. Their relationship is built on trust, communication, and shared experiences, making Greller a key part of Spieth’s journey.
Family and Personal Life
Away from the PGA Tour, Greller enjoys a family life that balances the demands of his profession. He married his wife, Ellie, in 2013 at Chambers Bay in Washington, the same golf course where his partnership with Spieth had its early roots. Ellie, a former kindergarten teacher, has supported his career and often travels with him to tournaments. Together, the couple has one child, making their life a mix of family duties and the global travel of professional golf.
Their story shows the challenges and rewards of blending family life with a demanding career. While many weeks are spent on the road, the Grellers have found ways to share in the adventure and build memories together.
Why He Is Among the Highest-Paid Caddies
Michael Greller’s earnings are directly tied to Spieth’s performance, and during Spieth’s peak years, prize money reached extraordinary heights. Reports suggest that Greller has out-earned nearly 330 professional golfers in terms of career earnings, even though he has never hit a shot in competition. His annual income often surpasses six figures, and in top seasons, it rises above a million dollars.
This level of financial success puts him in the top tier of caddies worldwide. The combination of Spieth’s consistent performance, Greller’s strategic role, and their loyalty to each other has created a partnership that is both professionally and financially rewarding.

The Human Side of Golf’s Inner Circle
Michael Greller’s journey is a reminder that golf success is not just about players swinging clubs. Behind every champion stands a caddie who manages pressure, calculates strategy, and provides encouragement. From his start as a math teacher in Seattle to his current life as one of golf’s wealthiest caddies, Greller has proven that timing, trust, and dedication can create extraordinary opportunities.
He may walk behind Jordan Spieth during tournaments, but his influence is felt with every decision and every clutch moment.

His $10 million net worth in 2025 is not just a financial achievement but also a reflection of years of loyalty, teamwork, and steady guidance in some of golf’s most dramatic moments.
