A few days ago, my husband and I visited the offices of Sullivan & Co., to complete the signing process for our 2025 federal and state tax returns. It's the month of July, so clearly we were filing late tax returns, and the reason for our lateness is that we have recently retired from an overseas job and have a slightly more complex tax situation than many families. Over the last few months, we worked closely with Raj Goenka, who listened carefully to our questions, and guided my husband through the tax process. After years of foreign earned incomes, we were grateful to have Raj's knowledge of both the US and Indian tax system were invaluable and set us completely at ease. In the final phase, we were also grateful to have a helpful, patient, and knowledgeable guide -- Patrick McMahon -- to help us complete the process. When we were unable to log into the Sullivan company portal to e-sign documents, Patrick patiently troubleshot until we were able to complete the signatures and file the tax returns to federal and state governments. Patrick's patience was key. He answered all our questions and made us feel welcome and valued as customers.

This was the first year that Sullivan & Company prepared my personal income tax. My tax situation is a bit more complicated than others because it involved foreign pension income, brokerage accounts, property rental, and a house sale. The Sullivan team showed a real expertise in all areas, combined with an efficient and secure system for document transmittal, great and accessible customer service, timeliness, and integrity. Thank you Sullivan & Co for the great service.
We have been working with Sullivan & Company for over 30 years and it has been a wonderful experience. Everyone at the firm has provided outstanding service. Since last decade, Ms. Benkovic has been handling our personal as well as business accounts and we couldn’t have been happier. Over the years, we have recommended this firm to many of our friends and colleagues.
I had excellent experience with Sullivan & Company, CPAs. From the very beginning, Mrs. Radka Windt and her team demonstrated a high level of professionalism, responsiveness, and genuine care for the complicated situation of dealing with tax codes in the US and abroad. What truly stood out was the personalized attention I received, every question was answered thoroughly, and Mrs. Radka Windt took the time to explain complex matters in a way that was easy to understand. Mrs. Radka Windt and the entire team clearly bring a strong depth of expertise to their work. Their guidance gave me confidence that everything was being handled accurately and efficiently. It’s rare to find a firm that combines technical excellence with such a client-focused approach. I highly recommend their services to anyone looking for reliable, knowledgeable, and attentive CPA support.
