What Our Clients Say

The Masler CPA team is very courteous, professional, and helpful in solving financial concerns. They thoughtfully consider each situation in context of our business before providing feedback. They are an essential component of our company’s financial journey, and we highly recommend them.
Arion G.
Excellent CPA firm! Very responsive, helpful, and knowledgeable with various tax laws that we needed help with!
Jenny B.

Masler & Associates is an excellent CPA firm. Sharon has been doing our taxes for years and is always very thorough in making sure we claim every deduction allowable. Our taxes are complex due to working out of country and also owning a business. Masler & Associates knows how to handle all the minutia. Most importantly, everyone at the firm is “down to earth” and very helpful. I would highly recommend them to everyone: from folks that have simple returns to those with the most complex tax situations.
Tom W.
Sharon and her staff have been a great help for us to understand not only tax laws, but also how to use Quickbooks, and keep it organized. Of course we could never do it all perfectly, which is why we feel so lucky that her team is very knowledgeable, professional, and always very patient. We have had a wonderful experience with them for the past 8 years, and we are definitely looking forward to keeping them as our CPA for many more. I definitely recommend her services.
Lori L.
Love these folks! I highly recommend them, especially for corporate and personal tax complexities. I give them a workout on my tax needs and they always come through with flying colors to find all the deductions allowed to save me big bucks!
David S.

The result of the audit, you ask? Masler & Associates turned an upside-down situation right-side up. Long story short, they negotiated our huge tax bill into a substantial refund!
John-Paul Beeghly
The crew at Masler and Associates go the extra mile to make you feel taken care of. They work hard to get every deduction possible, and push you to find every receipt so there is no questions later.
Dr. Jeff Van Rensselaer, Chiropractor

Masler & Associates is a knowledgable accounting firm. When I call with a question about deductions I am answered within 24 hours. M&A has helped me to pay less year after year.
