  • Ed Hsu, VMD
    The Honolulu Pet Clinic welcomes Dr. Ed Hsu. Dr. Hsu is a graduate of University of Pennsylvania School of Veterinary Medicine and also earned a M.P.H from the School of Public Health from the University of California, Los Angeles with a concentration on Tropical & Infectious Diseases & Parasitology. He completed an internship at the Sacramento Animal Medical Group with every intention of continuing in general practice, but the lure of emergency medicine was too much to ignore. After having worked as an emergency/critical care veterinarian at many of the premier specialty and referral practices in Los Angeles over the last 15 years, he is returning to general practice with the purchase of The Honolulu Pet Clinic. Known for his fondness for Pomeranians, lop eared bunnies and polydactyl cats, when not caring for his patients, Dr. Hsu may be found paddle boarding, SCUBA diving, riding his motorcycle, trying to work his way through a 10,000 DVD movie collection or spending time with his 2 dogs and 9 cats.

We are delighted!
