Our Doctors

Drs. Greg and Leigh Gallegos took over ownership of Lancaster Pet Clinic in June of 2010. They are both California natives who graduated from Kansas State University Veterinary School. After living and working in the Midwest for 12 years, they moved back to California to be close to family. They continue to do what they love, caring for our furry friends and are looking forward to a bright future for Lancaster Pet Clinic.

Dr. Katherine LeJeune has always had a love for science and animals, and has wanted to be a veterinarian since she was little. She grew up in Louisiana and moved to Mississippi to pursue her dream. After spending 7 years in Mississippi and getting her degree, she decided to travel west. She found a family at Lancaster Pet Clinic, where she began working in June 2017. Dr. Kat's furry family consists of her cats Imy and Miyu, and her Corgi, Winston.
