    Although she is extremely nice and personable, she does not manage her time well. I have been left…read morehanging countless times. Questions go unanswered, taxes asked to be refiled never were, appointment no-shows. VERY frustrating! She was great when she actually gets around to doing it, but the past year, she is distracted by her kids and family; which is totally fine- just admit it and go on a hiatus so clients aren't left in an anxious mess of confusion. Perhaps even refer out. After her filing an extension for me, then asking me to try and find more receipts to whittle the huge amount down, I was a bit frustrated. But I spent days of my time and did it. When I let her know I found a bit more, I received an automated reply that she was away on vacation yet again. DONE. I just can't wait any longer as we already delayed a new investment to see how our taxes went. And with the huge amount we were going to owe, we couldn't do the investment. So I did find another preparer who did my taxes in one sitting. Low and behold, he finds we owe THOUSANDS less than what she had told us!!! He said she probably forgot to input a few things to come up with those amounts!! DISTRACTED. And the refile we had asked her to do? It's now too late!! We can't do it! This makes me so upset- that's money left on the table! It takes me a long time to find someone I trust. I'd say about 90% of the tax preparers I've spoken to can not manage their time what so ever. I do not get phone calls returned, appointments set up, or any kind of personal consideration. It frustrates me to tears!

    My husband and I have been using Jelena's CPA service for years. She is well rounded and very…read morecompetent in her service. When we first went to Jelena she went back over the last 3 years of our taxes and we received a substantial refund. I love that I can send her an email with questions and get either a phone call back or an email response. I love the fact that you can meet with her in person OR transact via phone and email an or faxes. That really helps with my busy schedule. I have referred several of my real estate clients who have been helped in making confident buying decisions. Thank you Jelena.

    I can't believe no one has given Fred a review yet!!…read more Fred is amazing. I have recommended friends and acquaintances to him over the last several years. He has been doing my taxes for close to 10 years now! A friend worked in his office and recommended his services to me. My friend moved to Texas and I stuck with Fred. You can make an in person meeting or simply fill out the forms he sends you. He keeps great records and is super organized in everything you get. I receive my packet from him the end of December or the beginning of January (first week usually), so I can get most things filled out... if I didn't procrastinate. He also mails out monthly financial tips, stock information and well wishes. When I turned my taxes in this year (2021) for my 2020 taxes, it was the first time I saw him in person in at least a year. He greeted me by my name. I can barely remember people's names that I met after 10 minutes. This guy cares. I HIGHLY recommend him.

    I was referred to Fred from a member of the family years ago. My taxes can be pretty complicated…read morebut Fred helps make it a breeze. He let's me know what he needs ahead of time so that I'm not left sitting around for hours. Fred is honest, kind, and you can tell truly cares for you. He also has very fare wages. Fred sends out a cool quarterly letter with some fun information on it to get you thinking about your own life and finances. I would completely recommend Fred to anyone. He will do a great job for you as he has done for me for the last 6 years! Thank you Fred!
