When I switched to Collins Barrow for my accounting a number of years ago, they reviewed previous tax returns and recovered additional tax refunds for me. The fees were lower and the service improved. They are always there to answer any questions I might have. I am very happy with their service and would highly recommend Collins Barrow!
