Testimonials

"We recently transitioned all of its accounting and CFO type work to this firm. While it has only been a couple of months so far
we have been extremely
impressed. They have amazing attention to detail to ensure that the business is doing things properly and is not leaving any
holes in their books.

At the same time they are extremely pragmatic. They focus the most attention on the most important things and they ensure that processes are as automated as possible and cost as little as possible to the client. Having worked with multiple outsourced CFO’s, I cannot recommend this
team strongly enough."

"Their greatest strength is their absolute trustworthiness. We have absolute certainty that anything written or spoken is kept in absolute confidence. We also find them to be extremely responsive to our needs.  

I do not recommend people lightly. Our family is extremely pleased with their level of professionalism as well as their genuine care for our business."

"Rosenberg Chesnov has been an excellent accounting firm and business partner for more than five years. They have experts in-house in all areas of accounting/finance, and can grow alongside your business and adapt to your needs. They are very responsive, do excellent work, and are truly value-added partners to a business."

"I can only speak in superlatives. We have been getting so much personal attention since the beginning. …The firm has been instrumental in all of our business and financial decisions as we have been growing. [They] provide such a comprehensive financial and accounting coverage in every single aspect of our business."

"The team have exceeded our expectations. They have been a very responsive, knowledgeable, trusted resource for all of our accounting and financial needs. They invest the time and resources to answer our most simple and complicated questions giving us great confidence that we have hired the right firm for our business."

"They have been my company’s accounting firm for ten years and every year they earn my business through their financial expertize, focus and ability to help me understand the accounting details of the business. Their accounting work has been flawless and they have helped our firm to be more profitable. They have patiently guided my company through the confusing  small loan process offered by the government during the pandemic. They made the complex simple and were responsive to my many questions."
