Mehmet Ăz, better known by stage name “Dr. Oz,” is an American heart surgeon, media figure, author, and anti-transgender activist. Ăz was named head of the Centers for Medicare and Medicaid Services under the Trump Administration. In that role, Ăz carried out administration directives to attack transgender healthcare.
Background
Mehmet Cengiz Ăz was born on June 11, 1960 in Cleveland, Ohio, to heart surgeon Mustafa Ăz and Suna Ăz, both Turkish immigrants . Ăz grew up in Wilmington, Delaware. As a dual US/Turkish citizen, Oz completed 60 days of mandatory military training in the Turkish Army during the 1980s to retain Turkish citizenship. Oz has two siblings, Seval Ăz and Nazlim Ăz.
Ăz earned a bachelor’s degree from Harvard University in 1982 and a medical degree from Perelman School of Medicine at the University of Pennsylvania in 1986. Ăz also earned a master’s degree from the Wharton School of Business at University of Pennsylvania. Ăz completed a surgical residency at NewYorkâPresbyterian Hospital (Columbia University Medical Center) in 1991, followed by a cardiothoracic / thoracic surgery fellowship there in 1993. Ăz then joined the faculty at Columbia University Vagelos College of Physicians and Surgeons and was appointed Professor of Surgery in the late 1990s.
Ăz gained national visibility beginning in 2004 through frequent appearances on The Oprah Winfrey Show. Ăz parlayed this into The Dr. Oz Show, a daytime television program which premiered in 2009 and ran until 2022.
In 2022, Ăz entered electoral politics as the Republican nominee in the 2022 U.S. Senate election in Pennsylvania. Ăz was defeated by John Fetterman.
Trump Administrations
On November 28, 2018, US President Donald Trump appointed Ăz to the President’s Council on Sports, Fitness & Nutrition.
Ăzâs involvement with the administration expanded during the COVID-19 pandemic in 2020. In March 2020, Ăz was involved with strategies for reopening parts of the U.S. economy and schools while managing the pandemic.
On November 19, 2024, President-elect Trump announced that Ăz would be nominated to lead the Centers for Medicare & Medicaid Services (CMS). On April 3, 2025, the United States Senate confirmed Ăz as CMS administrator by a 53â45 vote. Ăz formally assumed office on April 8, 2025.
During June 23, 2025, Ăz worked with US Secretary of Health and Human Services Robert F. Kennedy Jr. to secure an industry pledge aimed at improving the prior-authorization process across public and private insurance plans. On February 25, 2026, Ăz announced a federal crackdown on fraud in Medicare and Medicaid programs.
Anti-trans activism
Ăz was not originally as strident about transgender people. On The Dr. Oz Show, Ăz aired a 2010 episode titled âTransgender Kids: Too Young to Decide?â that featured transgender youth and their families, including Jazz Jennings.
On November 28, 2012, Ăz aired an episode promoting the ex-gay movement and the National Association for Research and Therapy of Homosexuality (NARTH). In response to criticism, Ăz posted “After listening to both sides of the issue and after reviewing the available medical data, I agree with the established medical consensus.”
After being confirmed as head of the Centers for Medicare and Medicaid Services, Ăz began carrying out Trump Administration aims attacking transgender healthcare.
In April 2025, Ăz released a statement to coincide with a letter sent by Deputy Administrator and Director Drew Snyder
Medicaid dollars are not to be used for gender reassignment surgeries or hormone treatments in minors â procedures that can cause permanent, irreversible harm, including sterilization. We have a duty to ensure medical care is lawful, necessary, and truly in the best interest of patients. CMS will not support services that violate this standard or place vulnerable children at risk.
On December 18, 2025, Ăz published an op-ed in the Washington Post on “sex-rejecting medical interventions for minors.” Ăz cited Lisa Littman and ex-trans litigation among others in the piece, writing in part:
Americaâs children arenât lab mice. They deserve quality care backed by sound evidence and should not be conscripted as test subjects in risky experiments that cause irreversible harm.
Thatâs why the federal government has proposed two rules today banning the use of Medicaid and Childrenâs Health Insurance Program funds to subsidize sex-rejecting medical interventions for minors and prohibiting hospitals participating in Medicare and Medicaid from performing them. Extraordinary interventions such as cross-sex hormones and double mastectomies require extraordinary evidence, especially when children are involved. In this case, the evidence is lacking.
Comprehensive independent reviews â including by the Department of Health and Human Services, Sweden, Finland and Britain â conclude that the evidence that these treatments produce lasting benefits is âremarkably weak,â âlow qualityâ and âinsufficientâ to determine âlong-term outcomes.â
In the winter, Ăz convened a meeting on trans healthcare for minors. Attendees included:
- anti-trans hate group Society for Evidence-Based Gender Medicine
- authors of the 2025 US HHS report attacking gender affirming care
- American Medical Association
- American Psychiatric Association
- American Society of Plastic Surgeons
- Scot Glasberg (former head)
- American Academy of Family Physicians
- American Academy of Child and Adolescent Psychiatry
