Veterinary Assistant

Hi my name is Pat. My good friends call me Pat. Prior to my new and exciting role here at Happy Tails Animal Hospital I was working in the glamorous world of movie production. You may recognize me from my work on the Masked Singer, or Raiders of Lost Ark. Someday I hope to return to production and finish my work on "Gumby, The Real Life Stories from my Childhood". It's set to release in early 2031 with an All Star cast. When you're in the office don't hesitate to ask me about how George Clooney came up with the name for Casamigos. Boom....

Best vet ev-er!!! Lucy, my 2 yr old Boxer, loves Dr. Berka!! No more dragging her into the vet's office. She's super excited to see her doctor now and practically drags me behind her so she can see her!
Hi my name is Margaret and it's spelled just like it sounds. I'm a fun loving pet owner with a passion for watching people read and creating my own sub-titles to life. My fortunecookie said I would land my dream job, and I did. I'm an amazing cook and together my family and I have won 29 top cooking awards. I'm currently working with Pat (I'm a good friend so i can call him Pat) to produce my own cooking show but Martha Stewart has not yet confirmed to play my sous chef. I have pets and I love to talk about them, but I really like practicing my juggling routine in the lobby. Cheers and feel free to jump in and join my during my lunch break juggle sessions. They are epic and sometimes contain bowling pins on fire.

Your pet may end up loving her more than you. Paws down, the best furry life saver on Earth!

About Our Clinic

We met Dr. Berka when our lab Henry was having some health issues. She helped us through a rough time (and rescued us from an incompetent vet) with love for our dog, compassion for us, and expert medical care for our best furry friend. We would follow her anywhere (and we have for the last 3-4 years). We are so happy she now has her own practice because it means she is sticking around So Cal for good.
Keri was born and raised in Brightwaters, NY.  She received her Bachelor of Arts in Biology-Chemistry from Skidmore College in Saratoga Springs, NY, in 2000, and her Doctorate of Veterinary Medicine from the University of Missouri – Colombia in 2004.  When not saving small furry lives, she enjoys running, golfing, and hiking with her husband, Ethan. Ethan and Keri have lived in Huntington Beach since 2011. They have one “child” – Blue Great Dane puppy named Lavender Lee. 

One of our representatives will be happy to contact you within 24 hours. For urgent needs call us at: 714-891-7600

Hi my name is Alex. I have a dry sense of humor and I love making people laugh. When I'm not working here I can be found writing new material for my standup routine that I give on Saturday nights. My other passion is competing in plank challenges. I can easily do 20 minutes and if you challenge me I'm sure to win. Cheers and what do you say when a tarantula and spider cross the road? The answer is easy if you think about it. Why....
