I have dealt with many firms over the years. Finally found a firm that really prides itself on partnering with their clients. Many firms will complete your taxes, due your audits, and provide some level of consulting. Most of them really don't understand what your business really does. With GMA, they really want to learn and support the business they are working with. It is nice having this extension to our business. Great Partners!

Their billing is excessive and out of scope. I hired this firm because they asked for a very modest downpayment to start with, and was told, most of the work will be done by a junior book keeper to keep the cost down. I delivered to them all the numbers, and did most of the work myself. I ended up with an exorbitant bill. I am still fighting this bill and I am not able to pay it.

We have been working with Gross, Mendelsohn & Associates for over 5 years. During that time they have provided excellent guidance and expertise that has helped us increase the value of our company and minimize taxes. They are one of our most trusted and dedicated advisors. If you are looking for an accounting firm that will exceed your expectations, I highly recommend that you speak with them.

HIGHLY recommend Gross, Mendelsohn & Associates. If you are looking for an Accounting System Consultant, look no farther. Our company has been using them for 5+ years. They are EXTREMELY knowledgeable and quick to help. When we switched our accounting software several years ago their expertise made the transition seamless and easy. We had interviewed several companies at the time and they were an obvious choice as their customer service is simply the BEST. SO glad we made this choice!

They have always been and are continually there for us when we need them to help us figure out any accounting system issues. You will NOT be disappointed. Customer service is A++!

I have been working with Gross, Mendelsohn & Associates for about 10 years now and cannot say enough good things about this firm. They have always provided us with top-notch service from a staff that is extremely knowledgeable. In particular, Christina Haiss, CPA & Partner, has been my go to person for all of my accounting software needs and questions.

Through their guidance and expertise we have expanded and refined our own in-house processes. I would highly recommend Gross, Mendelsohn & Associates to anyone looking for a great accounting firm.

Gross Mendelsohn is a wonderful firm - we've used them for several years for nonprofit audit and accounting services, and can't speak more highly of them. They really care about the organizations they serve, and they are open to discussing different options, strategies, techniques, etc for getting things done. We have a great time with them talking through process and making things ever better each year!

I became a client and did not receive an invoice for almost a year, despite asking repeatedly for an estimate of the fees that were being incurred. When I finally received an invoice, it FAR exceeded my expectations and ability to pay. "Surprise" billing is not ethical, in my opinion and client communication is paramount in service oriented businesses.

For over 10 years Gross, Mendelsohn & Associates has been performing my works business audits, tax filings, and of course several dozen GAAP questions. They are always responsive, helpful, and a pleasure to work with. Highly recommended.

Switched to this accounting firm 4 years ago after 15 years with my old firm. Len Rus and his team have found opportunities and serve as a fair and balanced view on tax for my 4 companies and recently participated in a Private Equity conversion. Highly recommend without reservation!

We highly recommend GMA who have been our auditors for over six years through some really hard times. They have been extremely responsive and supportive through it all. Having been an auditor for a large international CPA firm, and having engaged many other firms from the largest to local, I truly appreciate their superb level of professionalism and ability to conduct efficient audits with well-trained staff.

I work closely with Chaim Fine at Gross Mendelsohn & Associates. He is always available to help guide my company through various complex questions. Even more importantly, he listens closely to the details so he can give great advice.
