Dr. Gerard Laheney
Senior Veterinarian – Shelter Medicine
Like many others, Gerard wanted to be a vet since the young age of 9. Having grown up in Port Washington, he learned from an early age of the North Shore Animal League as his family adopted their first of many animals in 1978. At the age of 15, and just recently having spoken with a friend of the need for a job, Gerard received a letter from North Shore recruiting local high school students. Gerard spent all of his high school years working as a kennel associate and later on the rescue team, and developed a passion for fostering neonate puppies. He went on to the University of Massachusetts at Amherst and received his BS in Animal Science (Pre Vet) and attended veterinary school at the University of Liverpool, UK graduating with a BVSC/MRCVS in 2001. He spent a year in private practice and found the most fulfilling aspect of this job was his contracted work with a local municipal shelter. In 2003, Gerard decided to ‘return to his roots’ and pursue a career at North Shore in Shelter Medicine. In 2007, Gerard was named a Senior Veterinarian and is primarily responsible for the intake of hundreds of animals weekly and managing the health of the 300-400 adoptable animals at North Shore.
Gerard currently shares his home with a rescued Catahoula, “Finn“, and a one-eyed cat, “Frisbee“.
