This group is not Shodokan, but somewhere amongst the non-competitive offshoots. There is a competitive mainline Tomiki-style dojo in Grove City. Their contact info can be found on the JAA webpage.

Rodger Pyle's lineage is Chudokai, but I don't think they are currently affiliated with anyone. Definitely a Yoshinkan flavor though.

There are also Yoshokai (another Yoshinkan offshoot) and Kokikai (Ki-society offshoot) groups at OSU.

Finally, there's one person that I know of who teaches a style of AJJ in Columbus, but I don't think he is teaching a public class. AFAIK he is doing what you might call MMA with a private group of students right now.
