      Accounting Review from Dmitrii Legetskii

      This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

      Cassidy and his team were able to help us clean up the mess our previous CPA had put us in. Our previous CPA advised us incorrectly on many matters. Cassidy and his team have been able to clean up, and advise us on future growth. With his help we have been able to focus more on growing our business. We have had no more tax surprises since we moved with him. We know how our business is going throughout the year, and how much in taxes we are expected to pay by the end of the year. We have taken advantage of CA tax credits that we had no knowledge existed. Cassidy and his team are extraordinary.Thanks for all your help and security you have given our business

Great team, great support and will be my accountant for long as I am doing taxes!!

No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis.

      BEWARE. We are an Australian firm who sought advice on engaging a US based employee. From the initial meeting with Janathan Allen, we were given incorrect, misleading advice that resulted in a huge financial loss and months of wasted time and stress. When we reversed our decision and trusted the firm to help us out of the situation, they were non-responsive and did not follow through with the required actions.Incredibly poor customer service. They told us what we wanted to hear - for example, they stated that as a foreign entity, we were able to open a US bank account and that they even had clients who had achieved this outcome. That information turned out to be incorrect.Be very wary about using this firm.

Our first meeting was so genuine, and subsequently after that--everything fell into place; the Advanced Care Directive - done, the Last Will & Testament - done, the Financial Springing Durable Power of Attorney - done! Burden worry off mine and my Mom's shoulders- DONE. I would recommend Allen Barron, Inc. to anyone about to get their Trusts or Estate Planning in order, affordably and headache free!

      I have used Curran and Associates CPA’s for my tax returns for over 6 years. A firm comprising honest, ethical, and diligent people, it has been a pleasure working with them. They take customer privacy very seriously and ensure timely filing of returns with periodic reminders on what a client needs to do. These reminders don’t just last through the tax season, but they are constantly in touch with their clients to remind them of their financial obligations like estimated taxes etc throughout the year. I would strongly recommend them to corporations and individuals who want a worry free tax filing and by the book tax accounting and advice. Thank you David, Ashley, and Kacie for all your help.
