Hear what our clients — individuals and businesses — have to say about what it’s like working with the Tandem CPAs team.

Can a CPA firm improve your life? In the case of Flewelling & Mitton (now Tandem CPAs), the answer is an enthusiastic “Yes!” As the Personal Representative for a family Estate, I encountered a seemingly impossible situation with the IRS regarding a significant tax overpayment. After months of letters, phone calls, documents submitted and resubmitted, I was still at square one. At the advice of the Estate attorney, I reached out to Flewelling & Mitton for assistance. They took this problem from me, resolved it effectively, and obtained the IRS refund check—all for a very reasonable price. I am a grateful client!

Like many people, doing my taxes has not historically been a “fun” process for me.  However, working with Rob Burton and his team has completely changed my experience. I feel we are in the best possible hands. Rob is personable, professional, compassionate and very knowledgeable. My husband and I have also worked with Jessi in his office with tax questions throughout the year and she has helped us to get our bookkeeping under control. She has made our life so much better by helping us understand what we need to do when, so that there doesn’t have to be so much stress associated with the process. As my business grows and things become more complicated I feel so reassured to have Rob and Burton and Company on my side. Thank you so much!

Thank you so much for your work on my brother’s estate taxes. . . . I’ve done my own federal and state taxes for many decades. . . . However, with my brother’s death last year it was a different situation. . . . When I looked at the 1041 estate tax forms and instructions, my confidence faded. While I thought that I might eventually be able to figure everything out, I really felt that I needed the help of professionals. Luckily, I discovered your firm and its wonderful people. . . . From the time I walked into your offices and met with you, I was confident that I had done the right thing. It was clear to me that each person there was not just confident — but competent. Every person was friendly and professional and there was never a moment when I doubted my decision. You quickly did your work while checking in with me, letting me know what additional documents you needed and why. You always kept me informed about your progress and I never felt overlooked or neglected. . . . I walked away from our meeting . . . secure that the cost of having professionals handle a matter like this was money very well spent.
