She is originally from Santa Monica, CA, and has been in the veterinary field since graduating high school. Leah started as a high-volume spay and neuter surgical assistant at various shelters in Los Angeles. After three years, she wanted to try out specialty/emergency medicine, and accepted a position as a radiology assistant at ASEC and transferred to the surgical department after a year. In 2016, Leah became a registered veterinary technician. Over the next five years, she worked primarily as a surgical technician and cross-trained in the ECC/ICU department.

She primarily taught fourth-year veterinary students during their small and large animal anesthesia rotation. Professionally, Leah loves critical anesthetic case management, local/regional anesthesia, exotics, teaching, and lecturing. Outside of work, Leah loves to try out local food spots, travel to different countries, play volleyball, swim, and snuggle with her mischievous cat, Obi.
