“As a small business owner, having to deal with one less thing is worth its weight in gold. Ashley and her team have made this process as easy as taxes could possibly be.”
Daniel, McLean
Quantum Accounting is simply the best. My tax returns, a combination of business and personal, are extraordinarily complicated but Quantum President, Ashley Sims, and her outstanding team always manage all of my accounting and tax needs on time and with the greatest precision. Demonstrating encyclopedic knowledge of tax laws and regulations, Quantum offers highly valuable guidance. The entire Quantum staff are supremely dedicated professionals, on whom I comfortably rely. And they also happen to be kind, good humored, and thoughtful, which makes visiting their office an absolute pleasure!

Quantum is the best. Been a Quantum client for more than 20 years (goingback to Bob Mitchell). Always professional and supremely knowledgeable.Every year they teach us something new and help us maximize my returns. Ireally enjoy the new online system. But we know if we brought a shoeboxfull of papers and receipts we’d still get top notch help and support. Ihad a unique situation handling my Dad’s estate in 2021 and they walked methrough it so my stepmother got the largest benefit she could. Can’t askfor a better tax preparer!

âThis was the first year that we used Quantum Accounting & Tax PLLC, although in past years we have dealt with Ashley and Michael when they were part of another accounting firm. We were very pleased with the service provided by Quantum in preparing out 2021 tax returns, and especially like the personal attention and personal relationships we continue to have with Ashley and Michael.  Ashley went above and beyond in researching tax consequences if we were to change our residence to another state.â

âI started a business almost three years ago after a 35 year career in telecommunications. Other than an accounting course in college many years ago, I knew and still know very little about accounting, let alone business accounting. When I started my business, many said that one of the first things you need to do is get a good accountant. So I started looking for one, and the first firm seemed more interested in taking my money rather than helping me with it. Then I found Ashley at Quantum, and I knew I had followed everyoneâs advice well. I had a good accountant that was fair, helpful, and competent and wasnât seeking to bill me for every word she spoke, but charges me reasonable fees for outstanding service. One day I hope to be paying Quantum a lot more money as a result of extraordinary growth in my company. How many companies can you say that about? Whether you are starting out or well established, it is clear that Quantum is who you should have in your accounting corner, they will always be in mine.â
