Meet Our Tax Pro

Zaira Valles

Hello there! My name is Zaira, and I am thrilled to be your go-to tax professional. I have a genuine passion for assisting individuals and businesses in navigating the intricate world of taxation. Being born in Brighton, Colorado, and raised in north Denver, I have a deep understanding of the local tax landscape, which allows me to provide you with the best possible guidance. With a strong background in business development, I bring a unique perspective to my role as a tax professional. Not only can I help you with your tax return preparation, but I also offer valuable insights into bookkeeping, payroll, and incorporation services. My goal is to give business owners peace of mind by taking care of their daily accounting duties and providing comprehensive financial reports. Throughout the entire business cycle, I will be there to guide you, ensuring that you have a clear understanding of your financial situation every step of the way. However, I'm not just a numbers and spreadsheets person! Outside of my professional life, I have a creative side. I enjoy indulging in various handcrafting activities, such as crocheting. When I'm not immersed in the world of finance, you can find me creating lasting memories with my husband and four children, cherishing quality time together. With my expertise, dedication, and passion for helping others, I am the ideal tax professional to trust with your financial needs. Whether you are an individual seeking assistance with your personal taxes or a business owner in need of comprehensive accounting services, I am committed to providing you with the highest level of professionalism and expertise. Let's work together to achieve your financial goals! And don't worry if you prefer to communicate in Spanish, as I am fluent in both Spanish and English.
