Evelyn Sagastume, DVM
Founder and Owner
In May 2014, Dr. Evelyn purchased an existing hospital and has worked hard on changing the practice to offer personalized care to the pets in her community. Today, clients enjoy a family-friendly practice that includes cutting-edge technology, a passionate medical team, and some of Southern California’s best doctors who are committed to the health and happiness of their patients.
In addition to a strong passion for preventive medicine and client education for her patients and their families, Dr. Evelyn has a longstanding interest in internal medicine, specifically the diagnosis and management of endocrine diseases like diabetes.
She also prides herself on being a practice owner who can shape her practice to provide progressive care and educational content to her clients in order to help her patients maintain a long and healthy life. She is passionate about ensuring clients have the information they need to be the best pet parents possible.
When she’s not at the hospital, Dr. Evelyn is an active member of multiple state and local veterinary medical associations. She is currently a member of the House of Delegates for the California Veterinary Medical Association. In her free time, she enjoys traveling around the world, participating in multiple outdoor activities, and playing the piano. She is also the proud pet parent of a very spoiled kitty named Mango, who you can catch up with every Monday on Petsadena’s Instagram page.

Eileen Reyna, DVM
Born and raised in Southern California, Dr. Eileen Reyna left her career in the fashion industry to pursue veterinary medicine – her true passion.
In preparation for entrance to veterinary school, she attended Pasadena City College and Cal Poly Pomona. In 2013, she earned her doctorate in Veterinary Medicine from Western University of Health Sciences. Since then, she has gained experience and knowledge working in Small Animal Practice for the past seven years.
Her professional interests range from dermatology, internal medicine, and preventative care, though her favorite part about veterinary medicine is educating and collaborating with pet parents in an effort to provide the best care possible for their furry family members.
In her leisure time, Dr. Reyna enjoys camping, hiking, and spending time with her family and 5 dogs – Abbie, Mochi, Taco, Bella, and Pugsley.
Erika Budde, DVM
California is the seventh and final place called home for Dr. Budde who was born and raised in the Midwest, attended college in New England, and then spent many years in Tennessee and Hawai’i.
Dr. Budde’s pathway into veterinary medicine was non-traditional. She graduated from Smith College in 2000 with a degree in physics. After completing internships in both physics and engineering she realized that was not her passion and instead applied the problem-solving skills learned from those experiences to the business world. Fifteen years later, veterinary medicine was calling and she could no longer fathom working in any other field. She completed the prerequisite courses at the University of Hawaiʻi at Mānoa and experience hours at the Honolulu Zoo before moving to SoCal to attend Western University of Health Sciences, graduating with her Doctor of Veterinary Medicine degree in 2020.
Her professional interests include public health, preventive care, and integrative medicine. She is currently enrolled in acupuncture training and hopes to be certified by June 2021.
Despite her busy schedule, Dr. Budde is an avid volunteer and firmly believes in giving back to the community. Her other personal interests are global travel, photography, and cooking.
