Dr. Jenna Dinstell was born and raised in the San Francisco East Bay Area. She became interested in medicine at a very young age after being inspired by her father, a pediatric hospitalist. After her first Catahoula Leopard dog passed away from bone cancer at the young age of two, she knew she wanted to become a veterinarian and help as many pets and their families as she could. Dr. Dinstell went on to obtain her bachelor in science in Animal Biology from UC Davis with a research emphasis in medical and veterinary entomology. Dr. Dinstell also obtained her Doctor of Veterinary Medicine degree at the University of California Davis.

Following graduation, Dr. Dinstell completed a rotating small animal medicine and surgical internship at a prestigious, referral, emergency and specialty hospital in West Los Angeles where she enjoyed a strong emphasis in emergency medicine and critical care. Dr. Dinstell made the move to Oahu four years ago and has been practicing small animal medicine in Kaneohe since. Her special interests include emergency and internal medicine, but primarily Dr. Dinstell enjoys client education and a collaborative approach to providing excellent care.

Dr. Dinstell resides with her husband, her two dogs (a husky/chow mix and an Italian Spinone), and a couple of guinea pigs. Outside of the hospital, she enjoys hiking, snorkeling, SUP, working out, and finding new places to eat with friends.

Shawna is a local of Honolulu. Growing up, she only had pet fish, but always loved animals! She attended Oregon State University and graduated with a Bachelor of Science in zoology with the initial thought to go on to veterinary school. After five years of being a veterinary nurse, she hasn’t thought of anything else she would rather be!

Outside of work, she loves to do anything outdoors. She brought over her dog, Samson, from Oregon, who also loves the outdoors. If it’s a nice day, you can find them hiking or at the beach, enjoying the Hawaiian sun.
