There are three groups that offer seminars, training classes and informal networking opportunities for statisticians in the Kansas City area.
The Kansas University Medical Center has a Center for Biostatistics & Advanced Informatics that offers a monthly journal club and semi-regular research seminars about Statistics. The main page describing these activities is
The UMKC Department of Mathematics and Statistics also has a regular seminar series, though some of these talks are mathematical rather than statistical. The current web page is out of date, but you can look at the titles of some of the past seminars to get a feel for the topics covered.
The Kansas/Western Missouri chapter of the American Statistical Association holds 2-3 meetings per year, typically in the evening. Again, the web page for this group is out of date, but offers some ideas about the general topics.
