  • "I have worked with Nicole for many years now. I first started as her client back in 2016 as I was beginning my career as a CRNA. I was working a 1099 job at the time, and I needed a CPA to help me navigate the ins and outs of taxes when it came to a position such as this. Nicole was so helpful as I got started and was always so willing to explain and answer questions. I have since switched to a W2 job, but I remain a very happy client of hers! My husband is a general contractor and has been a 1099 for a couple years now, and she has helped him tremendously as well. I have referred many CRNA’s to Nicole as the anesthesia world has many Locum/1099 opportunities right now, and it’s wonderful to have a CPA who understands the intricacies of our job when it comes to filing taxes. I highly recommend Nicole for all your tax needs!"
