CHAWLA & ASSOCIATES REVIEWS

I had a fantastic experience working with Mr. Roger Chawla and his team at Chawla & Associates CPAs. From the very beginning, the professionalism and attention to detail stood out. The team was not only highly knowledgeable but also incredibly patient and responsive. They took the time to explain everything clearly, answered all my questions, and made sure I felt confident throughout the process. I especially appreciated how approachable and accommodating everyone was—they made something as stressful as taxes feel easy and manageable. It’s rare to find a firm that combines technical expertise with such a high level of customer care. I’ll definitely be returning and highly recommend them to anyone needing tax or accounting help.

I recently got my taxes done by Mr. Roger Chawla and his team at Chawla & Associates CPAs, and I couldn’t be happier with the experience. Mr. Chawla was extremely professional, and the entire team was both competent and thorough. Everyone I interacted with was friendly, accommodating, and made the entire process smooth and stress-free. It’s clear they genuinely care about their clients. I highly recommend them for anyone looking for expert and reliable CPA services.

I have known been going to Chawla and Associates for over 14 years. Roger has developed a firm based on expertise, trust and professionalism. Roger truly values interpersonal relationships. I have appreciated a welcoming environment and consider Roger to be a long-term friend. I also respect his commitment to community service! Having recently moved to out of state, I still come to Roger Chawla to get my taxes done to attain peace of mind. The service is excellent, and the team that Roger has assembled is dedicated, professional, and detail oriented. I wholeheartedly endorse, without reservation, Chawla & Associates CPAs for all your tax, accounting, and advisory needs.

SUSAN S. LEWIS LTD REVIEWS

What a great team to work with. Even during busy tax season, we received quick responses to our questions along with excellent guidance and advice. We had hired Susan's team for tax season but enjoyed our experience so much we are working with them year round now.

My family has been going to Sue since I was a child. Now I use her as well and will continue until she decides to close her doors. Best accountant around.

I have been working with Susan and her team for 15 years tomanage my small business accounting needs. They are always accurate, timely, and able to address all my concerns. I highly recommend this group.

LEE MANDEL & ASSOCIATES REVIEWS

I would not think of doing my taxes without Lee Mandel’s expertise. Since 1995, I have consulted him and always received thoughtful and accurate answers. Lee is also an excellent business adviser, always getting to the core of sound decision-making. He has a lively and positive intelligence that is contagious. I leave Lee’s office with new examples demonstrating that he is the consummate entrepreneur. For this reason, he understands the individuality of his clients. In short: Lee has a comprehensive knowledge and understanding of tax law and preparation. He has a quick grasp of one’s business needs, provides thorough counsel, and has a great sense of humor. He is the most competent and personable person I have ever worked with on this unpleasant task.

You can’t have a better business consultant in your corner. Lee has helped me launch two successful companies. He not only helped me identify the best business structure, but he was invaluable in getting our financial and operational processes in place. Lee has been there to support and mentor me and key members of my staff. He’s even played a business development role by introducing me to numerous people he felt could benefit from our services. In fact, we’ve generated over $250,000 in new business because of Lee. Show me another accountant who does that.

Great firm with great people. Long history of dealing with Lee, and he’s not only a tax expert, but a very valuable resource for asking for an accounting perspective on business operations and possible ventures. Great guy, and great people.
