Report
I was referred through the hospital I work at and have to say my experience was exceptional. The amount of time and patience was greatly appreciated and is unfortunately the exception in today's world instead of the norm. Additionally, Mr. Feinstein's knowledge of tax law is extraordinary and he is truly passionate about his work. I highly recommend them.
