Recommendation, Leonard Sudberg, MD

[2BNTV]

Does anyone have any recommendations for Leonard Sudberg MD?

Looking to switch plans and was looking up doctors. For the life of me, I don't know what the "DO" stands for.

If a doctor says he has "Internal Medicine" as his specialty, what is the difference "not being board certified" and "board certified",mean?

D. O stands for Doctor of Osteopathy. A DO is not an MD.
