He was surrounded by his loving wife, Phyllis, who, along with family and friends, will deeply miss his presence.

Dr. Mackie’s legacy extends far beyond his immediate circle. He is survived by his sister, Onah Dee, and nieces and nephews, including Sheila, Corinne, Jonathan, and Chris. Members of the veterinary community worldwide will remember him for his unwavering kindness, spirited personality, and profound passion for animals.

A Lifelong Commitment to Animal Welfare

After earning his Doctor of Veterinary Medicine from Washington State University, Dr. Mackie began his career in animal clinics in Chicago and San Diego. He eventually settled in Los Angeles, where he was struck by the significant number of unwanted pets and the pressing need for affordable spay and neuter services. Partnering with fellow veterinarian Phil Weida, DVM, they established four low-cost spay and neuter clinics throughout the Los Angeles area.

Dr. Mackie’s innovative approach has played an essential role in reducing the population of unwanted pets in the region. He developed a surgical technique that enabled spaying and neutering of animals as young as eight weeks old. His method gained recognition, leading him to travel across the United States, Mexico, and Japan to share his expertise with fellow veterinarians.

A Passion for Adventure and Lifelong Learning

Outside of his professional achievements, Dr. Mackie and his wife enjoyed traveling extensively. They explored numerous countries by land, sea, and air, embodying a spirit of adventure. In his own words, he expressed a sense of fulfillment, stating, “…even if I go tomorrow, it’s been a great ride!”

In memory of Dr. Mackie, his family encourages donations to animal rescue organizations, reflecting his lifelong commitment to animal welfare. His impact on the veterinary community and the lives of countless animals will be felt for years to come.
