We started working with Mark in 2011. Having just been through a terrible experience the year before in which my wife and I caught countless mistakes (committed by the previous CPA) that would have endangered our on-time submission of our tax return in 2010 (and open us up to the possibility of paying penalty fees), we were primed to be extremely scrutinous of Mark when first beginning to work with him. In the process of working through our tax-filing with Mark in 2011 though, we came to recognize that Mark is accurate, precise, and timely with his work. He also works diligently to ensure that we do not pay any more tax than we should. After our excellent experience with Mark in 2011, we have been working with him to file our personal and corporate taxes ever since. Additionally, he has been readily available to my wife and me to expertly answers any questions or calm any apprehensions we may have. If you're looking for an accountant who is attentive to you, pays attention to detail, and is precise, timely, and diligent in preparing your tax return, Mark's your guy :).
