Professional Summary

Remote Availability

My professional focus is to bring clarity to the US Tax Code for taxpayers everywhere. Please email me at or call 720.234.1177 for a complimentary consultation.

I am both a problem solver and a protector of taxpayer's rights. As a life long student of the US Tax Code I routinely embraces complicated tax problems and efficiently reconciles disputes with the taxing authorities. In my spare time I report on my experiences in my tax blog using plain terms for general understanding.

I have a vast network of friends specializing in business services from tax law to accounting to bookkeeping and find myself routinely connecting good people together to overcome all sorts of tax related challenges faced by both individuals and businesses.

My services are for hire exclusively for complicated tax matters unless of course you are a friend or family as I am always happy to help.
