Satisfied Customers
“When we came to AAG with the taxes for our business – they were a mess! Not only were we missing information but we weren’t writing enough off. Sonia was able to work with us and get our books back on track.”
“Recently moved to Newington and was looking for a new place to file my taxes. Just did my 2024 taxes with Sonia, and she’s gained a customer for life! Her entire office was very welcoming, and she made the entire experience very enjoyable and relaxing. I will be sending all my friends and family her way. Reasonably priced, completed my taxes right in front of me, explained everything, and extremely friendly. Thanks Sonia!”
