Several years ago, I was referred to Karin by a family friend. Since then, she has provided…read morereliable and accurate accounting and tax services for myself and my businesses. The reports sent to me every quarter are very clear and the attention to detail is fantastic. Every item that I send in is addressed and her office is more than willing to reach out for more information so that things are recorded properly. I really appreciate that kind of thoroughness. I look forward to my tax appointment every year. Karin is extremely easy to talk to and is always happy to patiently explain anything that I don't understand (which is a lot when it comes to these kinds of things). On top of her professionalism and volumes of knowledge on all things tax, Karin is so kind. She remembers and asks about my kids every year even though she's never even met them. Even the receptionists make a point to go out of their way and make sure everything is taken care of before and after the appointment. That's real customer service if you ask me. To be honest, it makes me sad that I only get to visit the office once a year! If you're in the market for a CPA, I highly recommend Karin.

She is always welcoming and wanting to help most important looking after her customers as if they were family. And giving advice on how to be able to save money in the future, which is rare. I am shocked to read what a recent customer (BRYCE W, ANNETTE O & ROBBIN) wrote about her none of it is accurate. I am confident that Diane does not make mistakes in such like not filing correctly or not filing if she said she was going to and did not. I recommend Diane Barocio over and over again to friends and family. She is an amazing, considerate, kind And most important HONEST individual. Which is very rare in the tax business. Her business name says it all "QUALIFIED" the majority of the people out there who do taxes are not.

I was told in a very rushed manner to call back after the April tax filing deadline after I had initially made contact with a female representative here. I even explained what I needed assistance with. Well, I called back after that time hoping to secure an appointment for the same reason, and then I was told by the same female subject that no assistance would be provided to me. I was instead advised to consult with a tax attorney. At the last minute, I ended up calling a 75+ year-old tax prep who used to do my family's taxes in EAST LOS ANGELES decades ago (who still sees clients in his home), and he knew exactly which form I was referring to. The gentleman literally walked me through the F.T.B. form in less than 10 minutes. He even invited me to send SMS pictures so he could review my work... at no cost. What a glaring difference.

Until she was supposed to do my 2021 taxes, she asked me if she could asked for extension on filing. Until this past October, she did not file my tax on time. I ended up having to use another CPA and paid late fees to the IRS. I left at least 3-4 voicemails and 5 follow up emails. She never called me back or replied to my email to let me know what was going on. It shows a lot that she has 0 care for her clients. It would be nice to at least email me that she couldn't do my tax. But she was just gone and missing in action. Plus I just got a letter from IRS penalties of $1680. Be careful with this service

I've been to other places who can do what they do AND get me more money back for $150. This company tacks on BOGUS and ERRONEOUS charges and try to get away with it. I apparently paid for an hour meeting with my CPA that cost $275. Let's make it clear, I've never seen or spoke to my CPA. Couldn't even tell you what she looks or sounds like. But according to them, this so-called "meeting" occurred and that is included in the $750 bill statement. If by 1 hour meeting, they're referring to the survey that was emailed to me and I filled out in 10 minutes and emailed back to them, then I'm being charged $275 to tell them about myself on a sheet of paper. Additionally, despite filling out the survey and sending the appropriate documents AND telling her to not hesitate calling me with questions, my CPA seemed to forget that I purchased a house and did not include that in my taxes. I immediately made her aware and she made sure to charge me an additional $150 for having to "redo my taxes". What's disappointing in all of this is that they will not admit to any of their mistakes. Despite several phone calls that go straight to voicemail and emails that went ignored for months, they had the nerve to email me ONCE just once with the same bill statement AND added charges! An additional $72 in late fees. Which I find odd, because despite the original bill I received and questioned, I never EVER heard from them again whether it via mail or electronically. It was to the best of my knowledge resolved seeing that after my most recent email questioning all their bogus charges went ignored - I was to assume they dropped my bill and recognized their error. I think I've made more contact with them regarding this outlandish bill, than they EVER did in doing my taxes. I'd like to add that I have never made an negative Yelp review, let alone a yelp review AT ALL, but this horrendous business and their less than par service could not go ignored and I did not want anyone else to be used and abused by this so called CPA Firm. Lesson learned, go elsewhere to someone who cares more about their customer than squeezing every dime out of an innocent woman. $750 bill for: all of maybe 3 days spent doing my taxes ($325), an invisible meeting I apparently was at ($275), and to have them fix a simple mistake they made ($150). I WILL NEVER USE THEM EVER AGAIN!!!!

I highly recommend her services!

I had very high hopes, but in the end I was very disappointed. I was initially impressed with the…read moreemails and reminders that I received from Mariette about our upcoming meeting. She seemed very on-the-ball. When we talked on the phone, Mariette was professional, friendly, and knowledgeable about bookkeeping. However, I felt rushed in our telephone conversation. Telephone conversations are one price, whereas if you want to meet with her in her office she charges much more. The fist time that I had a bad experience with Mariette was when I had scheduled a telephone conversation with her weeks in advance. Then just before the meeting, she asked to reschedule. I'm busy too, but I understand if we have to reschedule. However, she is booked weeks in advance and to have to reschedule an appointment with Mariette can now take about a month from the first time that you wanted to talk to her. I then asked to be rescheduled to a different date and time that she suggested. I called her at the time we had scheduled and I didn't know that she had scheduled with someone else at that time. She said that I had asked for that time, but that she didn't confirm that appointment with me. She said that I had to request that appointment within a 72 hour window. I understand what she means, but she also didn't tell me that she couldn't make that appointment with me because she gave it to someone else. So here I am with an appointment in my calendar to discuss something with her that I wanted to tell her about a month ago and if I have to reschedule again then I have to wait another couple of weeks. Then she told me that she would call me, but never did. I actually think that Mariette is a victim of her own success. I'm sure that she's good. I'm sure that she knows what she is doing. But I'm also sure that she is too busy for me and inconsiderate of my time. I see how many 5 star reviews that Mariette has and I realize that this one star review goes completely against what others have written. But none of the other reviews are from a Yelp Elite member or with anyone with more than a handful of reviews. And I seldom give a one star review.
