Dr. Ellen Jefferson has spent the last 20 years, since graduating from veterinary school, trying to make her city nokill. She first tried mass spayneuter efforts, spaying or neutering more than 100,000 animals in Austin, Texas. When that did not work, she turned to the shelters data and found that many of the problems that existed could not be fixed by community spayneuter programs. She then refocused her efforts to address each problem systematically and created lifesaving paths for each type of animal at risk. Now, Austin has been a nokill city for over eight years and is the largest nokill city in America, with a 98 raw save rate. She has taken this methodology to cities like San Antonio, where the save rate has moved from 30 to 90. She now splits her time between two teams, working to keep improving the Austin model while also working with her American Pets Alive team at Maddies Academy to offer apprenticeships and shelter assessments to hundreds of shelters across America.
