The Viva Team

Dr. Dennis Leon

Dr. Dennis Leon earned his veterinary degree from Cornell University in 2001. Following his veterinary education, Dr. Leon worked in a busy multi-doctor practice in Hayward, California, where he also served as a veterinary consultant to the City of Hayward Animal Services Bureau, Hayward Animal Shelter, Alameda County Animal Control, and San Leandro Animal Shelter. He moved back to his hometown of New York City in 2004 and worked as a relief veterinarian at several small animal hospitals in Manhattan prior to becoming the medical director at Levittown Animal Hospital in 2005. In 2012, Dr. Leon began teaching third and fourth year veterinary students when the Cornell University Hospital for Animals selected him as the Robert W. Kirk DVM Practitioner-in-Residence. After a brief stint in Las Vegas in 2015, he relocated to Portland in 2016. He shares his home with two cats and a dog: Luke, Willamina, and Grace.
