Here are some organizations which promote the study of philosophy and specific sub-fields of philosophy. If you have an interest in philosophy, it is worth learning more about them!
American Philosophical Association. The American Philosophical Association "promotes the discipline and profession of philosophy, both within the academy and in the public arena." I've been a member of the APA since 2010, and presented at, offered comments at, and chaired a number of sessions at its annual divisional meetings.
American Association of Philosophy Teachers. The AAPT is "dedicated to the advancement of the art of teaching philosophy. " It provides many resources and newsletters to help philosophers who do significant teaching of undergraduates or others improve the quality of the education they provide.
