I originally came to Michael Allen with an incredibly complicated tax problem that was caused by a previous 'well respected' accounting firm. Not only did Michael resolve the problem in a timely and efficient manner he saved me a fortune in penalties and his fee was more than reasonable. That was 18yrs ago and I have been with his firm ever since. He has never made a single mistake on my tax returns. I use Michael for all financial planning advice. Not only is the work professionally handled his staff (many of whom have been with him for 20+ yrs - people never leave him) are all very courteous
