Tricia M., CVPM – Hospital Administrator

Bio coming soon.

Kelly L. – Director of Nursing

A love for science and animals led Kelly to study animal physiology at the University of California at San Diego. She says her work at Irving in the veterinary field is a perfect marriage of her two passions.

At home, Kelly enjoys spending time with her 3-legged Persian cat Sasha, and her Shepherd/Husky mix Mollie. Kelly says Mollie, a naughty and stubborn puppy at first, helped teach her about canine behavior. Mollie has since turned out to be an awesome companion!

Nate A. – Director of Customer Relations

Nate is a San Francisco native and has lived in the bay area for most of his life. When he was just out of high school, his passion for animal care became prevalent as he began working with shelter dogs. That passion eventually lead Nate to further his pet care career, joining the team at Irving. When he isn’t at work, you may find him playing hockey or inline skating, or enjoying his senior chihuahua - Milo Francis Abernathy IV.

Yuumi W. – Office Manager

Born and raised in San Francisco, Yuumi has a degree in child development and taught toddlers to third graders for 13 years before making the switch to the veterinary field. She has loved animals since she was a small child, and prior to becoming an employee, she had a cat who was a patient here at Irving Pet Hospital.

When she’s not working, Yuumi enjoys reading, eating, taking naps and chasing after her children.

Adriana, RVT – Assistant Nursing Manager

Adriana is originally from Tegucigalpa, Honduras, and grew up in southern California where she attended Humboldt State University, earned her degree in political science, and met her fiancé, Amir.

Shortly after graduation, she realized that her true passion was caring for animals, so she started working at a doggy daycare and on her new goal of becoming an RVT. She took an alternative route course through Veterinary Allied Staff Education to become eligible to take the VTNE, and she passed!

At home, Adriana has a basset hound named Reuben, aka Booboo. He enjoys long naps on the couch and going for walks at Fort Funston. He treats everyone he meets like they’re his best friend. When she’s not taking care of your furry families, Adriana likes to go to the beach with Reuben and Amir and spend time with family and friends.

Nani – Expansion Specialist

Nani’s real name is Sharon Marenco, but she’s been called “Nani” for the past 18 years. Born and raised in the Mission District, Nani graduated from UC Davis with a bachelor’s degree in Animal Science and Management. In 2002, she returned to San Francisco to work as a specialty nurse with SAGE Veterinary Centers. Three years later, she transitioned to management roles, ending up in the SAGE San Mateo location, where she oversaw all aspects of hospital operation.

A life-long animal lover, Nani has loved and taken care of 10 dogs, two cats, and innumerable fish, reptiles, and birds. She doesn’t currently have any pets, but she pet-sits for a golden retriever so often she is like her own dog. Nani is kept very busy by her five children, three of whom are active in travel sports. She loves being outdoors and watching her kids play and compete.
