Very happy with our new tax firm DeLeon & Stang. We followed Crystal Stewart there who has always been helpful and responsive, and given us expert advice. This was a very easy process, and the team does a great job.

Rich Stang and his colleagues have handled all our tax matters since 1988. Everyone in the firm is responsive and professional in every aspect.

-2023 Update- Still excellent! Their communication is very good, they will keep you informed throughout the entire process. (Still expensive though) -2020 original review- I really enjoyed the tax service I got from these guys. They do an excellent job preparing your forms and informing you if you are missing any documents. They also provide general financial services if your interested. Just be warned, they are not cheap at all. Infact, this is seriously one of the most expensive tax accounting firms I have ever used! $$$
