About me

I have been practing in the area of family law primarily for 21 years.   I concentrate my practice on representing individuals going through dissolution and paternity matters as well as Motions to Modify cases in the State of Missouri.  I practice in St. Charles, St. Louis, St. Louis City, and Jefferson County.   My goal is to work with clients on a one-on-one basis to get them the best results possible.   Client involvement is important to me because it gives me the best opportunity to get to understand the case and needs of my client as we work through their case.  The other portion of my practice is estate planning.  My goal in the area of estate planning is to provide my clients with effective solutions to their estate needs at a reasonable price.
