Yes

Dr. Mike is a currently practicing Family Physician that obviously makes good money on YouTube with 14M subs, and just gives pretty standard medical advice while covering interesting topics in his field and dispelling common medical myths.

The worst thing I can say about Dr. Mike is that he is very much an Old School Democrat and procapitalist/anticommunist, as evidenced by his podcast guests and his statements about his upbringing in Russia. But those are his political views. As far as I can tell his success on YouTube has to do with his looks, personality, and production quality alongside sound medical advice and interesting insights into the medical field.

I'm pretty sure at this point he has a whole team managing his channel, so he still has time to be a full time doctor. It's extremely rare for a legitimate currently practicing doctor to be able to be a youtuber full time, but it does happen.
