Amir Dowlatshahi, Irvine, CA

I have been a client of the firm since the mid 90's and  for that reason,I have had the opportunity to not just meet some but all the staff at the firm, for that reason I do feel that in this day and age if a firm is capable to retain a client for over 15 years,that speaks volumes,in this day and age and with the abundance of all services,you would be hard pressed to find a firm that still calls and knows you by first name,and even sends reminders so you would not fall behind,I have used the firm on a business capacity,and for personal  taxes,in one short sentence,I never feel there is anything to worry about when it comes to accounting/and taxation category,as long as I use this firm,and in this day and age,there is one less thing to worry about,great job to all of you,I remain... .

ZKCO is an excellent CPA firm in Irvine.  They are hard working, trustworthy and responsible.  Their knowledge of difficult tax issues is extensive, and they are very client service oriented.  I highly recommend the firm.

Gina Chironis, CPA/PFS, MBA, Irvine CA

Many clients of a CPA firm, as it is with any “specialized “ field, may find it challenging to  draw a direct correlation between the final product and the fees charged, since due to the lack of knowledge of the work, they often over simplify the process therefore concluding that  the service may have been over  valued.

I have had the fortune of working with ZKCO , both as a client and a management consultant for a period of time. I  have experienced  the  superb service and  witnessed  the degree of care and due diligence they undertake, when dealing with their clients' financial affairs.

Every staff member at ZKCO has been cultured, to treat the client’s business as their own and not over look even the minute details . The partners take even a higher level of care in reviewing the work, and  testing every possible scenario, in order to achieve the optimum results  on behalf of their clients.

Building  client relationship, is a key  focus of the operation and a major contributor to the organization's long lasting success.

I have worked with  several CPA and financial firms.  Although most have been very professional, but none been a match for the superior technical expertise, and service that ZKCO provides its clients.

Mahvash Howell, Director of Finance- GSFI, Anaheim, CA

I have known Majid Zarrinkelk for more than 20 years and have enjoyed the benefit of his and his staff professional advice consistently. They are very knowledgeable, thorough and diligent in their work.

I highly recommend ZKCO to anyone who is looking for sound financial advice and proper tax planning.

Reza Ghaffari, Anaheim Hills, CA

ZKCO has been our CPA since 1992 and they are the most responsible, trustworthy, prompt group of people we have ever worked with. Mr. Zarrinkelk has personally provided the most professional level of service and has done taxes both for our several companies and our personals. In the past 22 years, we have been audited twice and both times, because of their great work, there were no changes to our taxes filed.

We wish them more success and we intend to work with them for years to come. We highly recommend them to anybody who is looking for a great CPA firm.

Jimmy Horriat, President and CEO Atlas ME, Inc.

I have been a client of the firm for nearly 20 years and am looking forward to being their client for the next 20 years. Majid's level of professionalism, keen attention to detail and comprehensive knowledge base are exceptional. That being said, the quality that is most unique when working with ZKCO is you don't feel like just another client, you are made to feel like family.

Joanna Capitano, Vice President, Feature Films, Digital Domain

I have been using ZKCO for the past three years.  I came to know Mr. Zarrinkelk and ZKCO through couple of references and after careful review I concluded that ZKCO is the accounting firm that I would like to use for my company's financial requirements.

With every meeting I was more and more impressed by the knowledge and experience Mr. Zarrinkelk.  He has quickly become the go to guy for my firm on all financial issues.

I have recommended ZKCO to all of my friends and will continue to do so in the future.

Kamran A. Peyman, President, MCR Technologies, Inc.

For those of you who have been audited by IRS before, you know that having to go through that experience for the first time is nerve-wracking and highly stressful experience that I would not wish on anyone. My friends advised me that I should get representation as it would be to my benefit not to go in front of an auditor alone and therefore, I selected an attorney who made matters worse by reinforcing the negative effects of an IRS audit. He dragged one audit for eight months and charged me thousands of dollars of un-necessary expense.

Mr. Kashefipour was highly recommended by a relative and close friend and I found him to be a truly client oriented and professional person with his office locally based in Irvine. I did not hesitate to set up an introductory meeting with him at his office. The moment we met, I felt so much at ease as our conversation was very reassuring and convincing. Mr. Kashefipour gave me his ideas on how he was going to approach the IRS agent and present my case based on the facts and data that he was going to develop. Being a knowledgeable accountant, he guided me on the proper techniques of getting support documentation and summarizing all the data into a format that he can easily present to the auditor.

I worked very closely with Mr. Kashefipour on gathering and organizing all the data and support documents and he explained everything very clearly that I could easily understand and follow. It was a great pleasure working with him. The audit was concluded in just one meeting – something that my attorney failed to do in three meetings. The IRS agent was in agreement with the submitted documents and concluded the case.

I could not thank Mr. Kashefipour and his staff more. If you are looking for peace of mind and excellent representation on an IRS audit or any other accounting needs, go to ZKCO office in Irvine.

Reza Ameri, Civil Engineer

The team at ZKCO, led by my good friend Mr. Zarrinkelk, has always gone beyond the call of duty to take care of me and my network of companies.   We are thrilled to be celebrating our 20th anniversary of doing business with them and look forward to 20 more years. We are extremely happy and proud to be a member of their extended family.

Kia Jam, President/Producer, K Jam Media, Inc.

Majid and his TEAM are my first call when I am considering any financial decision. They assisted my family through our worst times and all along gave us hope to keep moving to better times. Truly graceful and professional in all they do

Todd Ross, President The Ross Group, Inc.

Many years ago (1996) you, Mr. Kashefipour, advised me of putting myself on 60k salary through my own corporation even though my store was not making much profits at the time. Your advice was "In this country you must have strong financials if you want to grow".

The salary and good credit helped me purchase my first commercial property with a 90% SBA loan 4 years later and I was able to sell that property for a substantial profit and roll that into many other real estate investments. Today my company which is a full service real estate firm has had in excess of $450,000,000 in Real Estate transactions and currently over 2 million square feet of real estate under management. A good advice i s priceless. Thank you for your great advice
