About Me

I am a Tax Attorney located in Boulder and Denver Colorado. I specialize in reducing and resolving tax liabilities with Internal Revenue Service and all 50 states. I received my law degree from the University of Colorado in 2000 and have been in practice for over a decade.

My goal is always to find a permanent solution to your tax problem. I always strive to achieve the best possible results for you or your business in the shortest amount of time.


I was born and raised in Colorado and completed my undergraduate studies at Colorado State University in 1996.  I graduated with honors and then attended the University of Colorado School of Law in Boulder, Colorado where I received my Juris Doctorate in 1999.  I passed the Colorado Bar Exam in 2000 and have been practicing law ever since.


I currently reside in Louisville, CO where my wife and I are doing our best to raise three wonderful sons.  My family and I enjoy all of the outdoor activities that Colorado has to offer, including camping, hiking, biking, skiing, snowboarding and running.

    Mr. Claudell is an exceptional attorney. I have been an attorney for 24 years and served as a judge, magistrate, prosecutor, law professor, and private attorney. However, even with all of that experience, I learn from his answers on Avvo each and every day. If you have the chance, hire him in an instant.
