  • I am so greatly that Jay is my CPA. He is so professional and quick to answer all my questions and concerns regarding my taxes. Jay has been doing my taxes for 10 years and always satisfied with his professional work. I referred Jay to my friends and they are all very pleased with him. Also, he's very kind and friendly.

  • I am very happy with their service. I obtained tax return preparation services. Communication was fast and the CPAs are knowledgeable in tax law and regulations. I've asked them many questions, and they have answered my questions well. I will keep using them whenever I need tax services.

  • Top notch, highly recommend- this is a small accounting firm that is professional, prompt and communicative. I hired James Lee to handle my employment taxes at the last minute and he took care of the job all under 24 hours. I asked for him to help me file 940, 941, w2/w3-rates were reasonable.
