About Vet


I am an internship trained veterinarian with over 10 years of experience in the field of veterinary medicine. My primary experiences are with small animal medicine (dog and cat) and wildlife medicine. I currently live in the San Francisco Bay Area with my wife, dog, and cat. I have a passion for conservation and research. I strive to always bring my patients the most up-to-date evidenced based medicine available to them. I love taking the time to have in-depth conversations with my clients about their pets' conditions so keep those questions coming!

Fine print: Both California and Maine currently regulate veterinary telemedicine in ways to protect you as consumers and the quality of care your pet receives. I am a strong supporter of these regulations because I believe they protect you and your pet; there is no adequate substitute to a physical exam in veterinary medicine, unlike in human health care. The primary services that I can offer are:

A second opinion on patient treatments and recommendations (ie "does what my vet recommended make sense?" or "I'm not sure I understand what my vet recommended, can you help me understand what it is and why they want it for my pet?" but NOT "is this a correct diagnosis?")

General conversations about conditions (ie "My pet was recently diagnosed with some kind of liver cancer. I know its cancer, but I want to learn more about what my treatment options for him are." but NOT "my pet is throwing up, does he have liver cancer?")

Triage questions (ie "My dog is throwing up every 30min, do I really need to take him to an ER now or can it wait till morning?" or "My dog is scratching at his eye, my vet can't see him for two weeks, is that ok?" but NOT "my dog is throwing up every 30minutes, what's wrong with him?" NOR "my dog is scratching at his eye, what drops can you recommend?")

As part of our conversations I may offer potential explanations of what may be wrong, however these should not be construed as diagnoses. Instead, they are topics that you should bring up to your in person veterinarian. Veterinarians offering more than that in California or Maine may be breaking local regulations.
