Paul Renberg

I have been a CPA since 1985 but have only lived in Arizona for the past two years. Prior to this, I would come to Arizona during tax-seasons to help Mark out and then return home to Idaho. Taxman CPA;s has grown so quickly that Mark asked me to join him on a full time basis. A successful tax practice needs a face and a force. Mark is the face of the business and his association with his clients is what brings them through the door. I am more of the force and would prefer to sit in the corner with my head down and working hard. Mark and I have found a successful formula in this highly competitive industrious. I convinced my wife to retire early and relocate to the eat valley with me. To my surprise, she has fallen in love with Arizona and we both look forward to exploring the hidden treasures that the state has to offer. We are also huge baseball fans and have become followers of the Diamondbacks. It is great to have a local team to hitch your wagon to.
