Dr. Patty Thongnamsap & Dr. Andrea Hsu

Dr. Andrea was a second year student and Dr. Patty a new student when they met in veterinary school at UC Davis.  Fate led them to be paired as “Big Sib” and “Lil Sib” in the program, and they have stayed true to their relationship since.

Dr. Andrea graduated from veterinary school in 2008 and afterwards completed an additional year of internship training at an emergency and specialty hospital in San Diego.  She had such a great time at her internship, that Dr. Patty had to follow in her “Big Sib’s” footsteps to complete the same training program after she graduated from veterinary school in 2009.

Their friendship, experience, and shared dream to create a family and community focused veterinary practice led to their partnership at Animal Medical Hospital. They hope to share their love of pets with you.
