About Vet

I was born in Israel and raised on the island of Oahu in Hawaii. I have always had a passion for animals and veterinary medicine. Growing up I lived with dogs and cats, raised parakeets and ducks, cared for and rode horses, and volunteered at the Honolulu Zoo veterinary clinic.

I received a BSc in Animal Science from California Polytechnic State University (2009) and a DVM from Colorado State University (2014). I then returned to Hawaii and gained experience working in small animal clinics and a large animal ambulatory practice. I also operated a small animal mobile service. During this time, I explored and incorporated new technologies, including 3D printing (surgical planning/client education from CT images), practice management software, communication platforms, client satisfaction analysis, and health monitoring devices.

I am currently an epidemiology PhD candidate at the Ontario Veterinary College (University of Guelph), continuing to build my knowledge on the application of technology to veterinary practice as part of a unique research lab that focuses on health informatics, digital health, and emerging technology in veterinary medicine ( I lead research on the use of technology in the home setting, with the development and analysis of a pet health technology ecosystem as a tool in feline weight management and other chronic conditions.

In my free time, I enjoy traveling, hiking, camping, water sports, and playing with my adorable 5-year-old niece and hyper 2-year-old nephew.
