I have attended 6 training classes. Each instructor has been extremely experienced and educated regarding their topic matter. Instructors have also included veterinarians that perform wildlife medical treatments.
The experienced rehabbers are very good about mentoring new rehabbers to make sure the wildlife is medically treated properly and the novice can handle the long term care of the animal.
I think the long term dedicated volunteers have very good communication. Whenever I need information they are quick to answer my inquiry or contact the next person in the organization that can be of assistance. The volunteers donate an enormous amount of personal time to ensure the success of Sierra Wildlife Rescue as a viable organization for our community.
The workshops are varied and respected that they attract rehabbers from other wildlife organizations and even the Forest Service to attend.
