From your Politico article:

There’s no doubt that El-Sayed has top-notch medical credentials. He attended the University of Michigan Medical School and ended up receiving his medical degree from Columbia University College of Physicians and Surgeons. He has a doctorate in public health from Oxford University and worked as an assistant professor of epidemiology at Columbia for a year before moving to Detroit to be executive director and health officer of the Detroit Health Department.

Good enough for me.
