Sun's National Tae Kwon DO in Mundelein is no longer listed with dojos.info. Most likely this school is no longer in business. However, sometimes if a school moves to a new location, the owner may list the new location as a new Dojo on dojolocator.com, rather than updating the existing listing with new address.
Please see the current list of Martial Arts Schools in Mundelein, you may find another school offering what you are looking for.
If you are associated with Sun's National Tae Kwon DO and the Dojo is still operating, please contact us and request a re-activation of this Dojo's listing.
