The best thing about Mary…the online web organizer.  I love efficiency! No more wondering if the package made it to Mary in the mail.  No more driving to her office!   And the next best thing…her tax advice.  With two micro-businesses in the family, she always gives us sound advice that will withstand an audit (a dreaded fear).  We are grateful we moved our business to Mary.  It’s a comfort to be in good hands!
