Testimonials

What our esteemed customers are saying about us.
Mariya is great to work with, very diligent in her work and focused on making sure returns are filed on time. She helped me with my taxes which included a lot of K1s from partnerships and was able to add value by pointing out additional deductions my prior preparer had missed. I also appreciate the infrastructure she has in place to store returns in the cloud and access them in a secure manner anywhere as necessary. I would recommend her without hesitation and plan on staying with her for the long term.

Mariya is a true professional. I own a small business that was merely a thought when I first was introduced to Mariya. She gave me some insight, explained structure types, and ultimately gave me options for her services so that our relationship will remain scalable as my business grows. It is a huge benefit to have her as apart of that process. I know she will answer my calls and do her best to provide a solution when needed. Highly recommend.

Mariya prepared/coordinated my personal, partnership and gift tax returns from 2010 - 2014. She was knowledgeable and responsive to any questions I had and always delivered quality work on time. She also participated in discussions regarding tax and estate planning I did during that time.

As an Expat who has worked in several countries, KPMG has done my taxes in the past. My taxes are complex with foreign income, rental income in multiple countries and states, dividends, interest, LLC income, tax equalization, relocation income, etc. I have high expectations when hiring people who claim to be experts in their profession. It is very hard to find people today that are responsive and can actually perform to the level they claim. I can say Mariya is one of the very best professionals I have dealt with in many years. She did my taxes for her initial estimate, responded to my questions immediately 24/7 and did a great job completing my federal and state (two states) taxes. I would rate her overall service a level above what I received from KPMG. I highly recommend Mariya. She is a highly competent professional who is responsive and trustworthy.

Mariya was greatly helpful in preparing my 2016 tax return. She took the time to go through multiple phone calls with me to get a grasp a a fairly complex case (working between two US states and abroad, with international assets), and delivered her work on time. On top of that the use of an online portal greatly facilitated the exchange of documents. I would recommend Mariya to anyone looking for an efficient personal tax accountant.
