Elizabeth McCalley, DVM, CCRT


Helping animals has been my life’s passion. When I was 13 years old, I adopted my first dog, Coco, after many years of begging my parents. It was quickly apparent that Coco was very ill. My mom warned me that she might not make it. Not willing to accept that fate for my new best friend, I began researching her symptoms online. I asked my veterinarian to prescribe her a different antibiotic, and after taking the new medication, she quickly recovered. From that point on, being an excellent veterinarian was my mission. This led me from Texas to New York to pursue an undergraduate degree at Cornell University in animal science and back to Texas A&M University for veterinary school.

After graduation, I began practicing in Austin, Texas, for a major corporate pet hospital. I relocated with that practice to “America’s finest city,” San Diego. I instantly fell in love with the pet-centric culture of San Diego. After gaining much valuable experience, I decided I wanted to enter into a private practice setting to provide a more personalized experience for my clients and their pets. I became the medical director at a boutique pet clinic in Coronado. This eye-opening experience showed me what dedication to excellence in this field can do for pet health and nurture long-lasting relationships with pet parents. During my tenure there, I attained AAHA accreditation for the clinic—a feat only achieved by 15% of veterinary practices—and became Fear Free certified.

I am grateful to be able to work as a partner with my clients to ensure that their pets live long and healthy lives. I strive to provide every pet and pet parent with the quality of care that I would expect for my own dog, Radar.

Mollie O'Brien

Veterinary Assistant/Client Service Representative

Hi, my name is Mollie! I was born and raised in San Diego, and hope to never leave. I first started working in the veterinary field a year and a half ago, and I have enjoyed every day of it. My goal is to provide clients and patients with the same level of care that I expect for my own dog, Bear, who is a 10-year-old Shepherd/ Rottweiler mix. In addition to Bear, I own a corn snake named Copper, two African dwarf frogs named Chad and DJ, and a few fish.
