Dr. Mark | Medical Contributor & Investigative Reporter, ABC News

Dr. Mark is an award-winning medical and investigative journalist at ABC News.  Dr. Mark has extensively reported on healthcare reform in the United States including an ABC White House special with former President Obama in 2009.  Dr. Mark has also investigated the country’s high cost of medical care and critical drug shortages.

Dr. Mark has also covered a variety of breaking news stories; the 2018 Thailand cave rescue, the 2018 Pittsburgh synagogue shooting, the worldwide 2014 Ebola crisis, the 2013 Boston Marathon bombings and the Deepwater Horizon oil spill in the Gulf of Mexico in 2010.  He was one of a select group of medical reporters who was given access to the health records of Presidential candidate John McCain in 2008 uncovering new details about McCain’s melanoma diagnosis.  He has also reported on important mental health stories including a special with Sue Klebold, the mother of one of the Columbine school shooters.

Dr. Mark was part of the team that brought America the story of Bruce Jenner’s transgender journey in a landmark 2015 televised interview with Diane Sawyer.  The groundbreaking special earned the prestigious Alfred I. DuPont Award.

In addition, as part of the ABC News “Hidden America” team, Dr. Mark highlights issues vulnerable populations face like the struggle for millions of Americans to earn a living wage, the overmedication of foster children with antipsychotics, and the plight of patients facing the so-called practice of “patient dumping.”

Dr. Mark has also reported on a wide-range of topics including ISIS in America, a quirky story about Presidential Hair during the 2016 Democratic National Convention, Michael Jackson’s death, New England Patriots’ quarterback Tom Brady inspiring a young fan with a similar knee injury to his and a story about how Hollywood players reached “El Chapo”- one of the most notorious drug lords in history.

In addition, Dr. Mark is part of the ABC News team that received the esteemed Edward R. Murrow Award for Overall Excellence in Television in 2014, 2015, 2016, and 2019.  He was also the recipient of a 2015 ABC News storytelling award for one of his live broadcasts showing the inner workings of a doctor’s office.  He has also been nominated for a Peabody Award and three Emmy® awards.

Dr. Mark currently serves as Medical Contributor for ABC News and Senior Editorial Producer for 20/20 and the Diane Sawyer team.  Prior to this, he worked at ABC News’ flagship broadcast, ABC World News.
