I was introduced to Mark when I first moved to Denver several years ago. Two professional most people avoid would be a dentist and a tax guy. However, I look forward to seeing Mark each year. He is great at asking questions, explaining my taxes to me in addition to the service he and his staff provides.

Terrific guy and excellent accountant. I'm in the same building as Mark, so I chat with him a lot. He took care of my taxes and did everything quickly and thoroughly.

He has always done an excellent job keeping my clients informed, up to date, and he always gets the work done in time for our IRS deadlines. I would highly recommend 5280 Tax and Mark Christiansen for tax preparation, consulting, and accounting services. Thank you for all you do Mark!
