Is a comma needed after 'founder'?

Mr Raymond at 45 makes a political debut and has decided to no longer serve his former political masters. He may not pose a serious threat to the PAP for now, but gleaning from his Facebook posts, he seems confident that he can reinvigorate the waning SPP and help them regain a foothold in parliament, a feat that has only been achieved by the party’s founder Mr Chiam See Tong.

Is a comma needed after 'founder'?

Thanks.
