About Me

I am a St. Louis native and have been practicing law in metropolitan  St. Louis since 1975.  My primary areas of practice are divorce/family law (including divorce, legal separation, child custody, child support, maintenance, division of property and adult abuse) and general litigation (both individual and business litigation).  I keep my case load to a manageable level so that I can give each case the attention that it needs.  Your calls and emails will be answered the same day or at the very least within 24 hours.  I assume primary responsibility for each case.  You will not be "handed off" to a junior lawyer.  I make sure that my clients understand the law and their rights.  Client satisfaction is my primary goal.  My practice reaches throughout Missouri with most cases being in the counties of St. Louis, Franklin, Jefferson and Lincoln, as well as the City of St. Louis.

The choice and hiring of a lawyer is an important decision and should not be based solely on advertising.
