I strive to be both a knowledgeable and aggressive lawyer, and a friendly and compassionate person.

I am an alumnus of prestigious Washington University School of Law. I graduated in the top 15% of my law school class, with many academic awards and honors.

Before opening my law office, I worked for several years at a large St. Louis law firm representing major corporations in high-stakes lawsuits.  While this background gave me invaluable experience and training, I left that firm because, in truth, I chose the legal profession with a vision of helping individuals and small businesses.

My wife and I have three children - all boys.  I have maintained my home and my business in Lake St. Louis, in St. Charles County, for more than a decade.
