I was first hired at the Arguello Pet Hospital in the summer of 1968. I was hired as a kennel person to gain experience in veterinary medicine which was a prerequisite to apply to the veterinary schools. I continued working at Arguello Pet Hospital while I was an undergraduate student at the University of California, Davis.
I was fortunate to gain acceptance to the School of Veterinary Medicine, Davis and graduated in June 1974. After graduation, I immediately began working at the Arguello Pet Hospital as a veterinarian with Elmo Shropshire, DVM.
In 1982, I purchased the practice from Elmo Shropshire. It was a one doctor, one technician and one receptionist veterinary hospital. I dedicated myself to practicing and providing quality medicine and client service. This dedication has enabled the hospital to grow to its present state of six doctors and a staff of over twenty employees. The entire staff is dedicated to provide compassionate care to our patients, their owners and to one another.
My oldest daughter, Cecily, is a second grade school teacher in the Japanese Bilingual Bicultural Program at Rosa Parks in San Francisco. My youngest daughter, Jamie, graduated from the School of Veterinary Medicine, Davis, in June 2008 and has since been practicing with me at Arguello Pet Hospital.
After 40 years of practicing veterinary medicine at Arguello Pet Hospital, I developed several medical issues that required a medical leave of absence from July to December 2014. After this medical leave and seeing improved health, I had chosen to permanently retire from practicing veterinary medicine. I cannot adequately thank the many clients that supported me throughout all these years. I will sincerely miss our friendships and trust that was given to me.
As of January 1, 2015, I have stopped seeing patients at APH. My daughter, Jamie Ina, has taken the position of Medical Director and Chief of Staff. However, I am still helping Jamie with the management of the APH. You may see me at the hospital but it is only in a managerial position.
Since I was young, I have always been around animals and grew up around the pet hospital. Growing up in a house full of animals, a wonderful father as a mentor, and a love of biological sciences, I knew I wanted to become a veterinarian. I began working at Arguello as a technician when I was in high school and always came back during the summer to continue learning throughout my college years.
I studied animal science and earned a bachelor's degree from UC Davis in 2004. I began veterinary school immediately after with an emphasis in small animal medicine. I graduated from UC Davis veterinary school in 2008 and have been working at Arguello as a veterinarian ever since. When I'm not working, I love spending time with my husband, our twins (Mikey and Natalie) and our two dogs (Yoshi and Nori).
In 2014, I began transitioning into the position of medical director with the help of my father. We both have similar work ethic and high standards of care, which made the transition very smooth and relatively easy. I am a very hard worker with a strong dedication to maintaining excellent care to our patients, clients and staff. When I'm not working, I enjoy spending time with my husband, my twins (Natalie and Michael) and my two dogs (Noriko and Yoshi). I love outdoor activities, cooking, arts/crafts, and gardening.
As a child, I dreamt of becoming a veterinarian, but in college, I found a new interest in clinical psychology. That all changed the summer of my junior year when I interned with a small animal veterinarian and realized that the six-year-old me was right and that my true calling was in veterinary medicine.
After graduating with a B.A. in psychology from Smith College in Massachusetts, I returned home to Southern California. There I worked part time as a veterinary technician and went to school part time to fulfill the prerequisites for veterinary school. I also spent a brief period working in human cancer research at the City of Hope National Medical Center.
I graduated from the UC Davis School of Veterinary Medicine in 2010 with an emphasis in small animal medicine. I then completed a one-year rotating internship at VCA San Francisco Veterinary Specialists in 2011. After my internship, I worked between two general practices in the East Bay before coming to Arguello Pet Hospital.
I love working at Arguello Pet Hospital with old and new patients alike. It is such a rewarding experience to be able to support my canine and feline patients from birth to old age. My spare time is primarily spent chasing after my toddler, but I also enjoy cooking new recipes, hiking, and travel (my most recent trip was to Japan...before having a baby).
I am originally from Southern California and moved all across the country before finally settling down in the Bay Area. I obtained my bachelor’s degree from the University of California at San Diego in computer science (double-minoring in cognitive science and sociology) and worked as a scientist at a startup company before moving to the east coast for graduate school in engineering. While I was out there, I made the challenging decision to switch career paths to pursue my childhood dream of becoming a veterinarian.
I completed veterinary school at Texas A&M University in 2010, was inducted into the Phi Zeta Honor Society, and graduated with honors. I then moved to New Jersey to complete a rigorous small animal rotating internship at Garden State Veterinary Specialists. A strong interest in complex medicine cases brought me to New York to complete a more intensive specialty internship in Small Animal Internal Medicine. My first general practice experience was at a busy and well-equipped veterinary hospital in California’s Central Valley.
I eventually moved to San Francisco and joined the staff at Arguello Pet Hospital in 2014. I am proud to be a part of such an amazing team and love that we are able to provide our patients with such a high quality of care. My special interests are in internal medicine, laparoscopic procedures, pain management, and dentistry. I am Fear Free Certified and am a member of the American Association of Feline Practitioners and the International Veterinary Academy of Pain Management.
In my free time, I enjoy exploring nature trails, birding, playing musical instruments, reading about and learning new things, and spending time with my husband, daughter, and two senior cats.
I grew up in Southern California, loving animals and deciding as a child that I wanted to become a veterinarian. I followed many others in the family to college at UC Berkeley, during which time I fell in love with the Bay Area and realized there is no better place to live. I went on to veterinary school at UC Davis, graduating in 1996. I've been working in small animal private practice ever since, with a little diversion to Portland, Oregon and Champaign, Illinois before I returned home to the Bay Area in 2005. I enjoy all aspects of internal medicine, and am especially passionate about client education and preventive medicine.
I live in San Francisco, and I like to spend my free time exploring the city, traveling, reading and hanging out with fellow Francophiles. Most of all I enjoy spending time with friends and family, including my cats Pia and Tiger.

I was born and raised in Los Angeles in a house that was always full of animals (cats, dogs, hamsters, chickens, birds, and many others). The special bond I had with each of my pets motivated me to pursue my dream of becoming a veterinarian. I received my bachelor’s degree from UC Berkeley, then worked as a veterinary assistant at a general practice and at an emergency clinic in the Bay Area for two years. I received my DVM degree from the UC Davis School of Veterinary Medicine where I focused on small animal medicine.
I love all aspects of veterinary medicine, but am especially interested in behavioral medicine, internal medicine, and surgery. I am passionate about building close relationships with my furry patients and their families as well as providing information to help pet owners make the most informed decisions for their pets. I am Fear Free certified and strive to make my patients feel as comfortable as possible during their appointments.
In my free time I enjoy being outdoors, hiking, traveling, weight lifting, and entertaining my Australian Cattle Dog/Border Collie rescue.
