Neither I guess.... But it depends on where you are taking your career. There is some component of compensation for admin time, but as a medical director of a level 1 trauma center with a residency program I can tell you it's more hours than the pay increase can cover for. Admittedly I have only my own experience. I have several friends in the community though, medical director, who say the same- the loss of personal and free time is not a one to one. Do this if you want it.
If your end goal is C suite, there are easier ways than the MD/DO route, but it can lead to higher leadership exposure and things like CMO. All depends on what you want....
I will say - do NOT do it with some grand vision of making money - it'll likely drive down your hourly rate if you are any good at it and give it that attention it deserves.
DO do it if you see yourself as a change agent, invested in your colleagues and your department, and feel comfortable finding the balance of metric whip cracking and simultaneously advocating for your colleagues and telling admin to shove it.... That balance is harder to find than you think lol
