Dr. Tan was born in London, England, and not long after, her family moved to Canada . She graduated from The University of Glasgow with her veterinary degree (BVMS, MRCVS) in 2002. After working in Scotland at the PDSA and an emergency hospital, she briefly moved  back to Canada. Following Canada, Dr. Tan moved to Texas, where she practiced veterinary medicine in  Austin for five years. Wanting to be closer to family, Dr Tan has settled in Bethesda.

 Special veterinary interests include surgery, geriatric medicine, pain management, and dentistry.  Since last year, she has been volunteering at The National Zoo with the primates as an interpreter for visitors. In her spare time, she enjoys the outdoors, especially with her two large mutts Achilles and Bruisor.
