Eric M. Irwin

Owner / Hospital Administrator
Eric's Bio
Eric owns Newport Mesa Animal Hospital with his wife Katie, and works as the Hospital Administrator. He has been working here since 2002, after basically growing up running around the hospital. After managing the clinic for 6 years, he purchased the hospital from his father, Dr. Tom. He enjoys working alongside his father (Dr. Tom), whom now strictly practices veterinary medicine anytime that he’s not out surfing! Eric previously worked as a firefighter in Central California but resigned after 6 years to focus on running the family business.

Outside work, Eric spends most of his time on the golf course. He played professional golf for a few years but now plays as an amateur in his free time. When he’s not on the links, he’s spending time with his family. Did we mention he is a die-hard Anaheim Ducks fan AND Green Bay Packers fan?

His pets include Penny (Chihuahua mix), Tobie (Tuxedo cat), Nancy (DLH cat), and Linda (French Bulldog).

Dr. Tom

Dr. Thomas M. Irwin (Dr. Tom)

Veterinarian/Medical Director

Dr. Tom's Bio

Dr. Tom is one of the most relaxed, down-to-earth vets you will ever meet. With over thirty years of small-animal practice experience, you will be in great hands here at Newport Mesa Animal Hospital. Haven’t met Dr. Tom yet? He will be the one running around in shorts and sandals, practicing medicine between sets at his favorite surf breaks.

Dr. Tom attended undergraduate school at University of Hawaii, where he fell in love with surfing. He then continued his education at the University of California at Davis and received his BS in Biology and Animal Science in 1978. He then continued his education at the University of California at Davis, where he received his Doctorate in Veterinary Medicine in 1983. A very “low key and down to earth” person – his practice philosophy is to provide progressive quality medicine in a relaxed, common sense, honest practice with the pets well being of primary importance.

His other passions include his family and recently welcomed new granddaughter Olive! Surfing, hockey and live music are also other passions of his. 

He enjoys spending 1 week per month in San Jose del Cabo surfing, relaxing, helping Dr. Ruben Pawling (local Veterinarian) and two local animal rescues in Los Cabos.

His pets include Miller (Orange tabby – who lives at NMAH).

Following graduation, Dr. Jennifer Keating happily accepted a full-time job offer to return to Newport Mesa Animal Hospital to work right alongside her lifelong Veterinary teacher, Dr. Tom.
