Need help with multiple if conditions

Or try this in E2 and copy down

Formula:

=--(OR(AND(OR(C2="MD",C2="DO"),LEFT(D2,3)<>"Dr."),AND(C2<>"",D2=A2)))

Neither of those worked for all contingencies, but they did help me find a solution of
=IF(AND(OR(C2="MD",C2="DO"),D2="Dr. "&A2),0,1)-IF(AND(OR(C2<>"MD",C2<>"DO"),D2=B2),1,0)+IF(AND(OR(C2="MD",C2="DO"),D2=B2),1,0)


Thank you so much for all your help!
