We found Eric and ESY tax group through a friend. It has been an exceptional experience working with them. Eric is professional and explains things very clearly, gives me the step by step so there are no confusions and communicates extremely well. He is very helpful and responsive. Very reasonable and great price as well. We feel like we are in good hands. I only wish we had found him sooner. I would recommend Eric to everyone!

I've worked with many other tax services in the past -- from filing it myself with TurboTax to other CPAs in the Bay Area and in Orange County and Eric surpasses them all in leaps and bounds. I've never had better guidance from a CPA or a bigger return! I've been using AT&A in Anaheim and they've got amazing reviews and haven't had an issue but we relocated and our normal tax guy left the group. We figured now would be a good time to find a CPA closer to us. I reached out to a handful and Eric was the most prompt and professional, with a client portal that was so easy to use. Eric takes his time, answers every question, and doesn't rush through the process. I didn't feel like a number but a teammate. I felt well looked after and he really cared about his work. Thanks so much Eric, we will work with you for as long as you'll have us!

​I cannot recommend Eric Yoon and ESY tax group highly enough! I came to Eric with a confusing and stressful tax issue, and he handled it with incredible expertise and ease. ​What sets him apart is his fantastic communication. He explained everything clearly with a friendly, approachable demeanor. He turned a high-stress situation into a breeze. If you need a tax pro who is as kind as they are capable, he’s your guy!

I had an excellent experience working with Eric Yoon at ESY Tax Group this year. I came to him with a challenging tax situation and a lot of stress about how to handle it, but Eric immediately put me at ease. Very quickly, he was able to assess the situation, formulate a clear plan, and agree to take me on as a client. What I appreciated most was his straightforward communication and the time he took to clearly explain my options and what the best path forward would mean. His explanations were detailed, practical, and easy to understand, which made a complicated situation feel much more manageable. I had actually contacted Eric the year before, and he advised me to reach out again the following year. When I did, he remembered me and was ready to help. He guided me through amending and filing my 2025 taxes and handled everything professionally and efficiently. I went from feeling overwhelmed and stressed about my taxes to having the entire situation cleaned up and resolved. That peace of mind was invaluable. I couldn’t be happier with the service I received and would absolutely recommend Eric Yoon at ESY Tax Group to anyone looking for a knowledgeable, responsive, and trustworthy tax professional.

Eric at ESY Tax Group has been great to work with. He helped me file the required documents for my LLC and also took the time to review my current tax year to make sure everything was prepared correctly by my previous tax preparer. What really stood out was how quickly he was able to look through my documents and immediately give helpful feedback. You can tell he knows what he’s doing. He explained things clearly and didn’t make it complicated. He’s also very prompt and responsive, which I really appreciate. I never felt rushed and felt confident after speaking with him. I’d definitely recommend Eric for both personal and business taxes. I’ll be working with him moving forward.
