Dr. Rebecca Swimmer grew up in the suburbs of Chicago knowing from the age of five that she wanted to become a veterinarian. It has been her lifelong dream come true to open Vet Villa Animal Hospital and to combine high quality veterinary medicine in a loving environment.


Dr. Swimmer’s educational pursuits began at the University of Illinois where she received her Bachelors of Science with High Honors in Animal Science. While an undergraduate, she developed a special interest in neurology and went on to pursue graduate studies at Harvard University where she graduated with her Masters in Neurobiology.


She continued her educational journey in Boston where she received her Doctorate of Veterinary Medicine from Tufts University. Research has played a large role in her journey, and she has been honored with training grants from the National Institute of Health both as a student at Harvard University as well as during her training at Tufts University. She has presented her research findings at veterinary conferences and has also been published in The Journal of Veterinary Internal Medicine.


After completing her formal education, Dr. Swimmer moved to Los Angeles where she completed a rigorous small animal rotating internship at the Animal Specialty and Emergency Center (ASEC). While at ASEC, she received advanced training with board-certified specialists in Emergency and Critical Care, Internal Medicine, Surgery, Radiology, Cardiology, and Oncology. She further applied this knowledge and honed her skills during her years as an emergency and critical care veterinarian prior to transitioning to small animal general practice. She has also enjoyed donating her time to the community by performing spays and neuters for local rescue foundations.


Dr. Swimmer's professional interests include preventative wellness care for both dogs and cats, trauma medicine, dermatology, and geriatric medicine including hospice care to improve comfort for older patients.


Dr. Swimmer loves sharing her free time with her husband, young daughter, and her two rescue kittens, Atlas and Squirrel. She is excited to be part of the San Gabriel Valley. High quality medicine, state of the art equipment, and compassionate care are the foundations of Vet Villa Animal Hospital.

Dr. Bailey Hand was born in Lihue Kauai, and raised in Laguna Beach, CA. She has been in the

veterinary field since the age of 15, working her way up from kennel attendant to veterinary

assistant to surgical and veterinary technician. An avid horseback rider, she rode in state-wide

equestrian hunter-jumper competitions, winning blue ribbons in numerous shows. She

interned at local equine surgical hospitals, and although horses will always hold a special place in her heart, Dr. Hand decided to pursue her passion in small animal medicine.

Dr. Hand obtained her Bachelor's Degree in Animal Science at Cal Poly, Pomona, and her

Doctorate of Veterinary Medicine at Carlson College of Veterinary Medicine at Oregon State

University. Although she enjoyed Oregon and the changing seasons, she was thrilled to return

to southern California and to join the team of professionals at Vet Villa Animal Hospital. Her

special interests include cardiology, ultrasound and radiology, as well as helping her canine and feline patients receive the best possible medical care.

During her free time, Dr. Hand enjoys spending time at the beach and in the ocean, trying

unique foods and restaurants in Pasadena, going to the gym, and tending to her jungle of house plants. She also loves to spoil her dog, Ellie, and her two cats Theodore and Clarabelle.
