About me

I began my focus on consumer protection legal work when a mover destroyed all of my furniture and gave me fake insurance information shortly after I passed the bar.  Trying to turn a negative experience into a positive one, I began volunteering as a consumer protection attorney for Legal Services of Eastern Missouri.  I volunteered there full time for several months prior to starting a law practice with a classmate.  I went on to found Flesner Wentzel, a general practice firm in St. Charles, Missouri. 

I handles civil litigation matters and estate planning.  My area of focus is consumer protection, including auto dealer fraud, home contractor disputes, debt collection defense, and representing tenants against landlords.


In my free time I enjoy traveling, rugby, and my basset hounds.
