Hear From Our Clients

Bruce Phipps

I am self-employed and my tax situation has become more complex over the years. Duncan & Co (specifically Michael) has cleared through the maze of tax code and the clutter of disinformation to make things much simpler and less stressful.

The client interface is simple: I upload my documents, he asks relevant questions and does the work. His fees are reasonable and the results speak for themselves.

I whole-heartedly recommend Michael Duncan & Co.

William Grimsley

Professional service from begining to end. I will continue to use Michael and would highly recommend his services.
