Try 'Witchvox' to look for other witchcraft practitioners or groups within your area.
Scroll to the bottom -> Pagan Groups -> Name -> City or Postal -> Type in empty box below -> VXsearch.
Or, alternatively- looking for just individuals, go to:
Pagan/Witch -> Name -> City or US Postal -> Type in UP or City in empty box below -> VXsearch.
With the postal code it should provide you with individuals or groups nearest to you/your area. If you select city it will look for those in your city only, which will probably decrease the likelihood of finding a lot of results.
Best of luck.
