Finally I have found the accounting firm that I've been searching for! Such a relief to be working with the amazing Mahdiyeh Hezarkhani at OG Accountants (and the rest of the team) - I feel like my business is in safe hands and all the stress and headaches of tax compliance is off my shoulders. Navigating all of the complexities of running an S-Corp was becoming too much for me and I needed to find an accountant who could help me understand things in a simple way and who I could trust completely to do everything correctly. Not only is Mahdiyeh extremely smart, savvy and switched on - she is also kind and warm and treats her clients as friends. I love the personal service and the ability to meet in person rather than over zoom. For complicated finance matters, everything seems clearer when someone can explain it in person. Absolutely recommend to small business owners who want experts to handle their finances and bring them the best results. Thank You!!

Referred by a colleague, I've been working with the OG Tax team since I formed my small business more than ten years ago. I design stress reduction programs and products, but OGT has reduced MY stress many times with quick responses, clear consult, and strategies for addressing financial challenges. You want to feel like you can call on your accountant any time, even with basic questions, and this is exactly what you'll get with OG Tax and Accounting. I'm really fortunate to have them as part of my 'team,' and highly recommend them to support your work and growth (and to reduce YOUR stress).

Working with Oleg and his team at OG Tax and Accounting Group for the past 10 years has been an absolute pleasure. Their expertise and attention to detail have been instrumental in helping me navigate complex financial matters with ease. They are always prompt, professional, and truly dedicated to their clients. I couldn't ask for a better partner in managing my finances and I highly recommend their services to anyone in need of top-notch accounting support.

We have been working with Oleg and OG Tax as a growing small business for over 10 years. There was two years stretch where we went to a more flashy start-up related CPA firm, who were horrendous (and who also went out of business) and we quickly came back to OG Tax and Accounting. Highly recommend.

My partner and I have used their tax services for over eight years. OG and his team are very hands-on, thorough, and professional. They are not cheap, but the prices are very competitive. What I like about using OG Tax service is that we can file our yearly taxes online instead of in person, which saves us time traveling to their South Park Slope offices, especially during the busy tax season.

Oleg & Team are great! Been with them many years and they've helped with all my company and personal accounting needs. Beyond the initial consultation this has all been remote. Would recommend them to anyone in the NYC area

For a very picky surgeon, Oleg and this colleagues are the best. Understanding and patient for someone with very basic financial literacy but also to the point and "let's get it done" in most efficient way possible. Have been with them for 3 years, and have not been happier :)

Genuinely incredibly satisfied with my experience working this office. Always on top of their work. Always reminding me of deadlines. Knowledgeable, professional, and friendly. I use them for both personal and business tax related issues. Most importantly, they utilize a modern approach, unlike many offices in Brooklyn that are stuck using antiquated methods of the past. Highly recommended.
