A Professional Society is an organization that provides a list of registered members who adhere to a code of practice and/or specialise in a particular field.

Submissions are reviewed prior to acceptance. Category allocation is at the discretion of the editor. A site may be relocated, or titles and descriptions altered to comply with ODP or category guidelines. Due to the high volume of submissions this process may take some time. Please be patient. Do not resubmit as this will result in a duplicated entry. Multiple submissions are not accepted.
