ATAX - Thornton, CO

"I had a great experience with ATAX, especially working with Guillermo Nieves. I recently moved from Florida to Colorado and my taxes were a little complicated this year. Guillermo was extremely patient and took the time to explain every step of the process so I could understand everything clearly. He answered all my questions, made me feel comfortable, and never rushed me. I truly appreciated his professionalism and kindness. If you’re looking for someone trustworthy and knowledgeable to prepare your taxes, I highly recommend Guillermo. Thank you for your help!"

"Guillermo was incredibly helpful and knowledgeable. He took the time to walk me through every step of the process and made everything feel simple and stress-free, especially since it was my first time filing taxes. Thank you again, I’ll definitely be working with you for years to come!"

"⭐️⭐️⭐️⭐️⭐️ Five-Star Review Guillermo is absolutely amazing at what he does. I was introduced to him a little over a year ago, and working with him has truly been one of the best decisions I’ve made for my business. His knowledge, expertise, and experience are unmatched. He didn’t just help with my books and taxes — he completely helped transform my business model, my mindset, and the way I approach my finances overall. Guillermo is patient, thorough, and incredibly knowledgeable, and he handles everything with grace and care. I came to him with a very difficult and complex situation, and he navigated it with professionalism, compassion, and excellence. He has truly been a blessing to me personally and to my business. He is hands down the best bookkeeper and accountant anyone could ask for. I will never use anyone else. I highly, highly recommend Guillermo to anyone looking for someone they can trust and rely on. You will not be disappointed."
