I was in St. Louis last weekend to present a paper, "An Abridged History of Chiropractic Extremity Care." My co-authors were Drs. Steve Troyanovich and K. Jeffrey Miller and the paper was well-received. It should be published in the journal of the AHC this year sometime.
The AHC is a great group of scholars and I really enjoyed my time with a fun bunch. Membership in the association has been down the past few years, so with an energetic new board and executive director, this is sure to be an exciting year for the AHC! I really encourage you to join and contribute. It's only $100 for doctors and $50 for students, so it couldn't be more affordable and the cause is a great one. Just make sure you don't use the membership link on the website at this time, as it doesn't seem to work. Check or calling on the phone to use a CC are better options.
The Association for the History of Chiropractic is also on Facebook, so join their page there, too.
