About Us


At Casillas Accountancy Group, our first priority is the success of our clients. Building our practice primarily through word-of-mouth referrals, we know the importance of strong, honest, efficient and enduring relationships. Our approach is personal. We enjoy making a tangible difference in our clients’ lives by helping them reach their financial goals.


Our team has been providing excellence since 1988. Whether we are computing thousands of dollars of savings from a business owner’s tax return, or devising a long-term plan for a successful future, we are dedicated to putting that experience to work by understanding the goals of our clients and providing effective results. We are committed to supporting our clients as their lives and businesses change over the years.


We believe community involvement gives us a chance to unite, expand our horizons and contribute to society in a meaningful way. Leading by example, founder Robbie Casillas enjoys coaching a local high school football team. Observing individual players unite as a team toward a common goal has been a rewarding experience for him, reinforcing his goals for Casillas Accountancy Group. Our staff continues to explore many ways to give back, and we encourage our clients to do the same. Together we can have a positive impact on our local communities.
