• Mehmet Oz was a practicing cardiothoracic surgeon before venturing into television and publishing
  • He hosts the long-running talk show "The Dr. Oz Show"
  • Oz is serving as the latest guest host of "Jeopardy!"

Dr. Mehmet Oz recently kicked off his two-week stint as guest host of "Jeopardy!" Here's how the controversial "Dr. Oz Show" host built his massive fortune long before gracing the long-running game show.

Oz’s current net worth is estimated to be about $100 million, according to Celebrity Net Worth. The website said he brings in roughly $20 million annually in salary.

After practicing medicine for years, the Turkish-American cardiothoracic surgeon started earning big due to his long-running talk show, TV show appearances and books, including 1998's "Healing from the Heart: A Leading Surgeon Combines Eastern and Western Traditions to Create the Medicine of the Future," which he co-authored with wife Lisa.

In 2003, he starred in the one-season Discovery Channel program “Second Opinion with Dr. Oz” before entertainment mogul Oprah Winfrey decided to make him even popular. Oz became a featured health expert on "The Oprah Winfrey Show" for over five seasons.

Winfrey then offered to produce, through her company Harpo Productions, his own show. “The Dr. Oz Show” premiered in September 2009 and quickly became a daytime TV ratings leader. He has since made regular appearances on the "Today" show and starred in other shows such as "Transplant!" and OWN's "Oprah's Allstars."

Oz has released eight New York Times bestsellers, including "YOU: The Owner's Manual," "YOU: The Smart Patient," "YOU: On a Diet," "Food Can Fix It" and the award-winning "Healing from the Heart," according to his bio. He has a quarterly bookazine, "The Good Life," and a regular column in O, The Oprah Magazine.

The TV personality also earns big from his relationships with drug manufacturers. Between 2013 and 2014, Oz was estimated to have earned $1.17 million from Covidien/Medtronic, which owns HET Systems, the maker of a hemorrhoid therapy he helped develop, according to an analysis by MedPage Today.

Oz also co-founded, which is described as "a comprehensive online health and wellness engagement platform," with former WebMD CEO Jeff Arnold.

With millions in the bank, Oz and his wife searched for the perfect home for their growing family. The couple finally found it in Cliffside Park, New Jersey, People reported. The Oz family bought the hilltop property and built a mansion that boasts six bedrooms and eight bathrooms with Mediterranean-inspired architecture. The home is valued at about $3 million as of 2020.

The Oz-helmed “Jeopardy!” started airing Monday and will run for two weeks, USA Today reported. However, the decision to invite him to take over as guest host sparked intense backlash from fans, with a number complaining that Oz’s controversies may ruin the reputation of the show established under its former host, the late Alex Trebek.

Oz previously came under fire for his controversial medical advice and admitted before a Senate inquiry that he did use his status to sell products without therapeutic benefits, Business Insider reported.
