Billy has been our tax consultant for a number of years. We have been extremely satisfied with his knowledge and expertise in preparing our tax returns. After our move to Florida, this past November, we were confident in his abilities to file our 2025 tax returns with a Zoom meeting. Whenever we call him with questions, he responds quickly with reassuring answers and direction. We are at ease knowing that Billy is trustworthy and will continue to take care of our tax needs in the future.
