I'm sure you know Mr. Kimura too.
Literal
Kimura-san [topic-は] you also honorifically-know-ご存じ [probably-でしょう].
ご存じ is the noun-form honorific (sonkeigo) for 'know' — equivalent in meaning to 知っている but elevated. でしょう is the polite tentative copula 'probably / I imagine,' often used to invite the listener's confirmation. Together they form a polite invitation for the listener to confirm that yes, they know Kimura. The も in あなたも ('you too') implies others also know him.
