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.
Dana Muwanas, DVM
Since she was a child, Dr. Dana Muwanas has always known she wanted to work with animals. She was raised around animals all her life, from farm animals on her family’s farm to small animals in her own house, and caring for animals has always come naturally to her.
However, the defining moment in Dr. Muwanas’ life that led her toward the veterinary field happened when she was just 10 years old when her family dog suddenly became ill and had to be rushed to the veterinarian. As her family stopped at a very small animal clinic, a veterinarian came out and took her dog in. Dr. Muwanas remembers watching as this veterinarian took care of her dog with great compassion and care. “I realized at that moment that I wanted to help save animals’ lives through medicine.” Dr. Muwanas says.
At 16 years old Dr. Muwanas started volunteering and later working at a small animal hospital in her local area. There she was mentored and able to work alongside great veterinarians that provided excellent care for animals. She got to learn the medical aspect from many different veterinarians as well as interact with clients and their animals, which she loved. She later pursued her undergraduate degree in biology and went on to be accepted into Western University Veterinary School where she gained her veterinary degree.
Being a pet parent herself, Dr. Muwanas knows how stressful and heartbreaking it can be when a pet is not feeling well. For this reason, she prides herself in always going above and beyond to treat her patients as if they were her own.
Dr. Muwanas has a special interest in internal medicine and surgery. She also enjoys teaching clients about their pets’ conditions and providing them with the best treatment options available.
She has a beautiful and energetic German Shepherd named Lexa that loves people and treats, and her hobbies outside of work include going to church, playing basketball, trying new food, and spending time with friends and family.
Emmeline Ye, DVM
Dr. Emmeline Ye has always loved animals, though she didn’t realize her dream of becoming a veterinarian until she was 20 years old. She started out as an Economics Major at UCSD and was completing an externship at an international bank in China when she realized she had no passion for what she was doing. It was at that moment she decided to pursue a career that would make a real difference in the lives of those around her. “I thought about what kind of impact I wanted to make and decided that I wanted to become an expert in animals”, Dr. Ye said of her early years. She was especially driven by her first dog, Coco, who inspired her to educate herself further on animals so she could provide Coco with a happier, healthier life. This eventually led to Dr. Ye wanting to provide a healthy and happy life for all pets, not just her own.
Realizing her passion, Dr. Ye made it a point to get the education needed to become a trusted source for those looking to enhance the lives and wellness of their four-legged family members.
Perhaps one of the most defining moments in Dr. Ye’s early career was again inspired by Coco. “Coco ended up developing a very malignant cancer but because I was in vet school at the time I was able to get her surgery and treatment and extended her life by 2 years.” Dr. Ye said. “That was another experience that further cemented my passion for Veterinary Medicine.”
Today, Dr. Ye continues to be inspired by animals, and especially by her patients. She is always in awe of how resilient and strong animals can be, and how sweet they continue to be even when they are not feeling well. Dr. Ye says she aspires to be more like her patients.
When it comes to treating patients, Dr. Ye makes it a point to always put herself in her client’s shoes. She strives to offer the best standard of care for pets because she would want nothing less than that for her own furry family members.
And speaking of her furry family members, Dr. Ye is the proud mom of four pets, including her two dogs Bean and Feta, and her two cats Sesame and Mianhua (which means Marshmallow in Chinese).
Some fun facts about Dr. Ye: She is fluent in Mandarin Chinese, and in her spare time she likes to play games on her computer and switch while listening to Kpop.
