I agree. It sounds wrong because of tense agreement. It should be "I WAS fortunate..."
Also, there's the implication that the candidate was named chair because of luck rather than merit, so they probably would have done better simply to humble-brag and eliminate the first part altogether: "I was named chair of this board shortly after I joined," but that's somewhat outside the scope of the grammar question!
