About the author 

Guss Markwell

Originally from St. Louis Missouri, I grew up in a strong Midwest and moral family who taught me right from wrong and to stand up for my rights and the rights of others. In these tough economic times, you need an advocate on your side. Why do I practice law? Often, people are facing seemingly insurmountable opposition with little or no ability to overcome great odds. It is my position that we should all be fighting for those who find themselves alone, afraid, and at times unpopular. I subscribe to the notion that a society should be judged by how it treats its most vulnerable members. I represent, and I fight for, those people. “There is light at the end of that tunnel, don’t stop.”
