Tax Preparation Review from Wendy Prest
Even though she isn't based out of Harvard, Alexa did an incredible job thoroughly reviewing and submitting my tax returns. The entire process was efficient, straightforward, and handled with great care. Absolutely no complaints from my end—I am very pleased with the work and attention to detail!
Tax Preparation Review from Kimberly Murphy
I have been using Alexander Accountants for my tax filings for several years now. This year, I brought them on to handle the taxes for my real estate business, and they made the whole experience extraordinarily smooth and easy. Their team simplified what could have been a complicated filing and provided reliable, hassle-free service every step of the way. I will certainly be returning to them again next year!
Tax Preparation Review from Aaron Coltin
After filing a tax extension, I reached out for assistance with my personal tax return. The team at Alexander Accounts responded immediately to all of my questions and concerns. Their collaborative, team-based approach made the entire process seamless, and communication was consistently prompt and clear throughout. I was thoroughly impressed with how smoothly everything was handled!

Sandra Smith's Review Sourced from Google
I they do not care about their customers!I have been with them for over 40 years! I was just notified I was no longer wanted as a client.I called and text 3 people I knew there, asking why they were canceling my simple tax account.NO ANSWERES. Then a month later I got an email saying they were down sizing!Is this how you treat a loyal customer of over 40 years that does a simple tax return? I always relied on this company and the people in it. I feel so disrespected. I would never trust them again.
Peter Keast, Sr.'s Review Sourced from Google
Computer technology has vastly improved many of our lives, even in the non-profit world. The issues are cost, reliability and maintenance. It is too much for a small business owner to become an expert in these areas. I'm not even sure it is possible. Having a partner - a paid vendor, yes, but a still a partner that respects your budget, responds quickly to problems as they arrive, and proactively seeks to protect your network from crashes and malware is invaluable. We feel like we have that partner with Whittlesey Technologies. Every year we meet to discuss vendor agreements and performance. Whittlesey Technologies has never been considered for replacement. They are our partner.

We have been using Whittlesey Technology as our service provider since the mid 2000’s. They have managed multiple server & software implementations over the years with ease while giving us the communication and proactive guidance we need. They have also provided very responsive day to day support. We look at Whittlesey as a trusted partner and part of our team.

Tax Preparation Review from Parhum Moshki
Dimov Tax was exceptionally helpful and fair-priced when assisting my family with complex tax questions that involved cross-border considerations. They made sure all of our filings strictly adhered to IRS regulations while maintaining the highest standard of quality. It gave us complete peace of mind knowing everything was handled professionally and completely by the book!
Tax Preparation Review from Gerald Triplett
Working with the team at Dimov Tax has been a fantastic experience. I have relied on them for my filings over the last four tax years, and I always feel confident knowing they genuinely look out for my best interests. They are dedicated, reliable, and consistently advocate for their clients!
Tax Preparation Review from Рубен Газарян
This is easily the finest tax firm I have ever worked with. As a long-term client who grew up outside the United States, I find the American tax system incredibly complex and confusing. However, Kirill Solntsev and George Dimov made my highly complicated 2025 tax return feel completely manageable. Kirill’s exceptional professional support, patience, and meticulous attention to detail were incredible throughout the entire process. They offer top-tier individual tax planning and filing services at a great price point. I wish them continued success and look forward to remaining a loyal client for many years to come!
