100% family owned & operated veterinary hospital in Costa Mesa, CA since 1983!

Dr. Thomas Irwin and Dr. Jennifer Keating along with our entire support staff are experienced in all types of veterinary conditions and treatments.

Watch us on CBSN Los Angeles!

“The veterinary industry is under huge strain to meet the demand with a 200% increase in new clients, 34% increase in pet adoption across the US, and a burnout rate among veterinary teams at a shocking 80%. Veterinary hospitals find themselves at 100% capacity daily, emergency clinics are experiencing 6-8 hour wait times and on occasion when they reach capacity they are unable to take on any more patients. Veterinary hospitals are strongly encouraging clients to book routine visits at least 4 weeks in advance and are asking clients to confirm their appointments to ensure sick patients and emergency cases can be seen in a timely manner.”

Our mission:

At Newport Mesa Animal Hospital, we strive to provide our clients & patients with progressive quality medicine in a relaxed, common sense, honest practice while treating your pets like the valued family members that they are.

We love our clients and patients!

Thank you for your kind words! We look forward to exceeding your expectations during every single visit.

I’ve been bringing my cats here for years. I’ve seen Dr. Tom and Dr. Keating. They’re amazing with my babies. They care for my animals as if they were their own. I’m always confident we’re getting the best care here. I wish they saw more types of animals so I could bring the rest of my creatures here!

Dr. Tom has been our family vet for over 25 years. He has a down-to-earth approach to medicine and doesn’t try expensive tests or new procedures just because they’re available. We highly recommend him as a vet to take care of your many generations of family pets.
