Dr. Tamara Oesterling

Tamara D. Oesterling, DVM (Dr. O) is a native Texan born in Austin, raised in Dallas. She decided at age seven to become a veterinarian often stating “it was a calling, not a choice”.

After spending several years in the Kansas City area, she returned to Texas in 2009 and created Heart of the Hills Veterinary Center. Dr. Oesterling’s professional career includes feline exclusive practice, pharmaceutical research, and development for Pfizer Animal Health (now Zoetis), adverse event reporting to the Food and Drug Administration (for Pfizer), and served as director of veterinary services and primary surgeon for the largest no-kill shelter in the Mid-West. In her spare time, she enjoys cooking, gardening, horseback riding, and collecting beads. Dr. Oesterling is in love with a gentleman, Tom, and lives in Boerne with her daughter, three cats, three dogs (sometimes more), and five chickens.

A personal note: January 2021

Covid-19 has affected my practice. The impact has left me in a place of confusion and wonderment. Our hospital hours are limited because I am short on staff and practicing medicine is more challenging, requires patience and creativity as things just aren’t the way they used to be. But I feel blessed. My clients have been amazing and understanding. I appreciate the support over the past year and hope we can continue to provide the best possible service in a climate of never-ending change.

Tank found his way to our clinic in May of 2010 at 6 weeks old. He won his way into our hearts and hasn’t left since!


Xena and her four sisters were left on our doorstep in September of 2009. Her siblings were adopted out to other homes and Xena stayed as a clinic cat. She is a prowler and is frequently seen dashing across the property in quick pursuit of small creatures.

Tinker Belle

Tinker is an Umbrella Cockatoo born in 2003. She came to live at Heart of the Hills Vet Center in February 2012. She has a lot to say and can be very demanding at times. She gets into a lot of trouble which makes for good stories for Dr. Oesterling’s Newspaper Column. A very tame and friendly Parrot who gives “kisses” and is happy to meet anyone, espcially children.
