5/5
"This team is excellent! They have completed my taxes for four years in a row, several moves, several small businesses, and some contract work. Response time is very fast and the service is friendly. They always answer all of my questions where other accountants get impatient. The common complications on my return have to do with deductions from 1099 income, which is how I found George in the first place (referral from a friend that was also on 1099). I recommend to friends and family." -Mariel Fry, Google Review
