About Us

Founded in 2016, Invisible Paw Prints is a 501(c)(3) non-profit organization. Our board members, staff, and members are all volunteers. IPP therapy dog teams visit hospitals, retirement homes, hospice, personal homes, children hospitals and even correction facilities and the list goes on! We find joy in giving back to our communities in such a wonderful capacity with animal assisted therapy.


Founder Rob Kortus, a retired Coast Guard helicopter pilot and certified professional dog trainer had a vision to create a therapy dog testing and registry non-profit in 2016 after writing a book (Invisible Paw Prints) about his border collie Sophie and her therapy dog work in the Charlotte, NC area and the wonderful people Sophie encountered. Hence the non-profit name today, Invisible Paw Prints.

Invisible Paw Prints was incorporated in 2017 and today, the IPP volunteer members and their canine companions visit 100 plus organizations to bring smiles and joy to many of those who need it. IPP therapy dogs will leave behind no paw prints, only trails of human smiles, happiness, hope, and love.
