The Evolution of Physician Influencers: 4 Doctors to Follow Right Now

Four physician influencers to watch: Wendy Goodall McDonald, MD, Jennah LaHood Siwak, MD, Zachary Rubin, MD, and Meghan Martin, MD, are making waves in healthcare with their engaging social media content, education, and brand partnerships.

As someone who specializes in healthcare influencers, I’m fascinated by how physicians build and leverage their social media presence. Watching them evolve—especially from the “before times” (pre-pandemic) to now—is both fascinating and fun.

Physicians are uniquely positioned as influencers, often walking a fine line between education, innovation, and public engagement. But what exactly are they sharing? What makes their content relevant, and who are they speaking to—peers or a broader audience? Is their community engaged? And one key question I always ask: Are they open to partnering with brands?

The diversity of their content is also worth noting. Some focus on data and innovations, while others engage with their audience through relatable, everyday health tips. Whether it’s discussing treatments, sharing study data, or raising awareness, physician influencers are evolving rapidly.

Physician Influencers to Follow

Here are four of my favorite physician influencers worth following:

  1. Wendy Goodall McDonald, MD – Instagram
    Wendy is an OB/GYN who educates with a great mix of humor. Her content covers everything from anatomy to labor to peri/menopause, and she experiments with different formats, including hilarious skits and reaction videos. Recent brand collaborations include Secret, ClearBlue, and Astellas.
  2. Jennah LaHood Siwak, MD – Instagram and TikTok
    Jennah is a family and obesity medicine doctor who delivers easy-to-understand education about obesity without shame or selling supplements. She provides up-to-date information on GLP-1 and other obesity medications, and her audience is incredibly engaged in her discussions around patient concerns and study data.
  3. Zachary Rubin, MD – Instagram and TikTok
    Zachary is a pediatric allergist and clinical immunologist, known as much for his medical expertise as for his signature bow ties and hula hooping. He educates his audience on topics like proper inhaler and epinephrine injector use (so needed!) while combatting misinformation. Recent brand partnerships include Fig App, Swiffer, and the American Lung Association.
  4. Meghan Martin, MD – Instagram and TikTok
    Meghan is a pediatric emergency doctor who shares intriguing emergency department cases, health education, and her own fitness journey. She also offers practical tips for parents, like creating a “sick box” for home health supplies—something I’ve personally found helpful!

These physician influencers are making a big difference by providing valuable health information and actively combating misinformation, helping patients make informed decisions about their care.
