There are links on the left hand page and if you scroll to the bottom you will see the link for Support Groups with lots of listings.
If you can recomend a Group or Counselor there is a link half way down the right hand page to add your suggestions.
There are lots of other useful links on this site also

I found that the specific link provided in the first post does not work. However, I typed in www.aplb.org and found my way in to the spot I wanted (the home page is a little confusing--the user has to click on "click here" to get to the resources it offers). It gave me some great information on how to help a child with the loss of their pet. Thank you very much!
