Your feedback matters

  • I met Kathy Gellis many years ago at a workshop, and it's been one of the best things that have happened to me. My office was stacked with piles and piles of paperwork. I was desperate. I had so much to do that I couldn't get one thing done. My stress level was to the roof, and then I met Kathy. She quickly processed the paperwork, and paid all the outstanding bills, applied for refunds I was owed, balanced my personal and business checking accounts, handled my taxes, she took over my entire business and personal finances. Kathy has been there for me in business, as well as a friend. She is honest, capable, and efficient at what she does. I would recommend her to anyone without a shadow of a doubt.

  • Kathy Gellis of Gellis Consulting, has been with my business for several years doing an outstanding job with my bookkeeping. She is honest , has integrity and has brought several areas of my business together. I am recommending Gellis Consulting for your bookkeeping and accounting needs. Her office staff is very helpful and very professional .

  • Kathy and her colleagues have been absolutely instrumental in the successful operation of our association. They have made my “volunteer” position actually enjoyable, leaving little about which I need to worry. Gellis Consulting is as professional, trustworthy and reliable an organization as I have ever experienced. I also chair my condo association back in Boston and only wish I had Kathy to work with there as well. And in a final tribute, Kathy has become family to us.

  • Kathy and her team have always been very polite and professional.  They have worked with many of our clients to get their bookkeeping and accounting lives back on track.  It is always a pleasure to find a team that will deliver on their promises consistently, and they are a great resource to have in your corner!

  • We are a small business and hired Gellis Consulting in 2015 to handle payroll, monthly and year-end tax filings through Quickbooks.  This has freed up time for us to concentrate on the production of getting work out the door.  Knowing we hired a qualified and experienced person to file all the necessary paperwork helps to reduce the stress tremendously.   Kathy and her staff are very professional and have been a pleasure to work with over the years.  I would highly recommend her professional services.

  • "I am a fully engaged entrepreneur and family man, and like many others living full lives, find myself excitedly chasing down one opportunity after another. However, something that I have never been excited about chasing down is my monthly bookkeeping and tax filing. Working with Kathy has been a pleasure. She is extremely professional, effective and accommodating. She was willing to go above and beyond to find methods that would work best for me and my business. If you find yourself either neglecting these important elements, or being frustrated by the time and effort they require of you, I encourage you to reach out to Kathy and discover how working with her might help bring you greater productivity and peace of mind."

She designed an accounting system tailored to the specific programs and management information needs of our not-for-profit. As a result, our officers and directors have financial information truly helpful to decision making. She is a pleasure to work with."
