Positive: Professionalism, Quality
For a personal, professional handling of all things taxes, the Sherbetjians are the best. They really know their stuff, and always take the time to answer all my questions.

You can't go wrong with the Sherbetjians -- professionals who really know their stuff. I always have a million questions, and they take the time to answer them all - even when I've left my tax prep until the last minute. I am confident that it's done right when I leave it in their hands. And you can't beat the friendly, inviting atmosphere that makes paying taxes somehow more bearable.

I've been with Hasmig for many years now. I cannot say enough wonderful things about her. She seems to know everything(!) and is extremely thorough - she will spend as much time with you as necessary to get the job done right. When I first went to Hasmig years ago, my tax situation wasn't the best - she helped me get on the right track and has always been very supportive. Such a warm personality and just an amazing person - she is a very patient and compassionate individual. Her son, Movses, is great and smart and obviously takes after Hasmig - he knows all the latest innovations

I met Hasmig 15 years ago when I moved to California and started my small business with very little in my pocket and didn't know anyone. Now I have grown my business to one of the larger businesses in Thousand Oaks with her help. All I can say is she can handle any tax prep from the small personal income tax to a larger company with multiple investments including income properties and acquisitions. There is no one I would trust more with my business. I remember on multiple occasions sitting in her office and she would have other experienced accountants come in to ask her advice regarding

I've been with Hasmig for decades - for good reason: she is extremely effective and efficient. I cannot recall the last time there was an error of any kind on my return (I do take the time to check every year). I do recall several instances where she knew about a new wrinkle in the tax code that I had no idea even existed. As an engineer, I really appreciate her focus and work ethic. As a person, I really appreciate her kind and confident demeanor: she puts me at ease every time. I am so very lucky to have found her.
