Board of Directors

Shoshana Tanner - Founder & Executive Director

Shoshana was diagnosed with bilateral hearing loss at age five and became profoundly deaf at fourteen. Her love of animals and desire to help her community drove her begin volunteering her weekends at a local animal shelter from a young age; there she was immersed in basic obedience training to help adoptable dogs find forever homes. In high school she developed complex partial seizures and severe vestibular migraine episodes. Originating from the personal need for a dog to assist with the effects of multiple disabilities and without a program able to provide such a dog for her unique needs, Shoshana began working with and training service dogs in 2009.

In 2013 she became heavily involved with training and program development with Canine Assisted Therapy (South Florida) where she also volunteered with her dog, Macy, by working with children on the Autism spectrum and those with other developmental special needs. Shoshana was a volunteer group leader for Southeastern Guide Dogs in Palm Beach Florida for a period of time before moving to Texas to train diabetic alert dogs.

Her passion of granting others independence through partnerships with highly skilled assistance dogs drove her to establish Topaz Canine Services in 2016.
