Dr. Kim Bercovitz, D.V.M.

Dr. Kim Bercovitz is Castro Valley Companion Animal Hospital’s Practice Owner since January of 2018. She is an East Bay native, having grown up right here in Hayward, California and attended Moreau Catholic High School. From there she went to the University of California at Davis where she earned her Bachelor of Science degree in Biology. As an undergraduate, Dr. Bercovitz demonstrated the combination of intellectual curiosity and a desire to be of service by acting as a peer counselor, studying American Sign Language (ASL), and doing research using a goat model for human Rheumatoid Arthritis.

Expanding on her interests in medicine and animal care, she then went on to receive her Doctor of Veterinary Medicine from the University of California Davis School of Veterinary Medicine in 2001. Ever a local gal inside she returned to Castro Valley to establish her practice in the field, helping animals and their human caretakers alike.

Dr. B as her clients like to call her lives in Castro Valley with her husband, two children, and four dogs. Dr. B volunteers with Early Alert Canines and in her free time enjoys camping, reading with her book group, and spending quality time with her “fur” and “not-furred” kids.

One of the most common things we hear is about Dr. B’s incredible bedside manner. She truly cares about both her patient’s and her client’s well-being, while also practicing the best medicine.

He routinely lectures on a variety of subjects at veterinary symposiums and conferences and is a strong advocate for the legalization of ferrets in California.

Dr. Gandolfi is one of the founders of Fix Our Ferals, an all-volunteer spay and neuter clinic for homeless cats, and served as it’s Veterinary Director for over 12 years. He taught the critical care course for the RVT Program at Western Career College and sat on the College’s Advisory Board. He also conceived and acted as Veterinary Director of the 1991 Oakland Firestorm Lost Pet Hotline. Before becoming a veterinarian, he taught high school Chemistry, Astronomy, and Algebra.

Today, Dr. G is moving his main focus over from General Western Veterinary Medicine to Traditional Chinese Veterinary Medicine and is only accepting new patients for TCVM. However, he will continue to see his existing patients for Western Medicine, as well as remain as one of our Veterinary Surgeons on staff. Dr. G has always been interested in his professional growth and is very excited to embark on this new journey in Traditional Chinese Veterinary Medicine.

And we are so very thankful she did. She is incredibly thorough and kind, always giving her all to every case she works with.

Our support staff:

Each of our staff members has a variety of domestic as well as exotic pets of their own at home. (We tried to get them to pose too but their agents wanted too much money for a photo shoot.) For you, our client, this means that they have personal experience in the care, needs, and handling of your special friend.

She had been a Registered Veterinary Technician for years, having worked with several of our staff and Dr. Bercovitz at another clinic. She came to Castro Valley Companion Animal Hospital along with Dr. B in 2011 but wound up moving to Yuba City after a few years. Now, several more years later after making the move, she makes the long commute to be CVCAH’s Practice Manager.

Marci resides in Yuba City with her husband of 16 years, and her two boys: Calvin, 14 years old, and Jason, 11 years old. And let’s not forget all of the different animals she has! They currently have four cats: a 5 and ½-year-old Domestic Shorthair named Spider Crab, two 4-year-old Domestic Shorthairs named Ninja and Mr. Squee, and lastly a 1-year-old Domestic Shorthair named Goonie.  Not to mention all the kittens she is constantly fostering and finding wonderful forever homes for.

But it’s not just cats that reside in Marci’s household. She also has 7 Tarantulas: A Chilean Rose Hair, a Mexican Red Rump, a Chilean Copper, a Green Bottle Blue, a Brazilian Red and White, a Chaco Golden Knee, and a Curly Hair Tarantula! She also has a Veiled Chameleon, a Leopard Gecko, two Box Turtles, and wild toads in her backyard. 

When she’s not at CVCAH, she’s working at the Yuba City Animal Shelter or going to business school. Marci is one of the hardest workers we have ever had the pleasure of knowing. Our team has only grown and improved with her leadership. Look forward to the many more positive changes she will bring to our practice!


Veterinary Technician

Angie and her husband of 20 years have been residents of Castro Valley for the past 17 years. She has always loved animals since she was a child, being that she grew up with every type of critter you can imagine, from Horses to Lizards.

Angie and her husband currently have over ten different critter children. They have two wonderful Labradors, named Rig and Moose, a 50 pound African Sulcata named Sammy, 2 Box Turtles, 3 Red Eared Sliders, several different fish and Koi, and a beautiful chicken named Booty. When Angie is not at work assisting doctors in the exam rooms, and helping Dr. Gandolfi in surgeries, she is an avid hunter and outdoors-woman, spending most of her spare time camping and hunting big game all across the United States.

Angie has been with Castro Valley Companion Animal Hospital since 2007. She is dedicated to and does an excellent job of making sure all patients, no matter big or small, are taken care of and given the love they deserve away from home.


Veterinary Technician

Lily was born in Castro Valley but grew up in Hayward. She is a graduate of Mt. Eden High School and has been in Veterinary Medicine since 2012. She is currently enrolled in Penn Foster to get her license to become a Registered Veterinary Technician. The love and concern for animals’ well-being must run in her family. For she has two sisters who both also happen to work in the veterinary field! She has two fur babies, a 6-year-old Chihuahua Mix named Ladybird and a 6-month-old Domestic Long Hair Kitty named Yumi.

Lily is really interested in Animal Dentistry and Surgical Procedures. Once she becomes a Registered Veterinary Technician, she will be able to be more involved in such procedures. She loves horror movies and musicals and is really interested in painting, sewing, crafting, and drawing. Her creative side was so strong that she originally thought she wanted to be a tattoo artist. However, her love for animals was even stronger.

We are very excited to have Lily on our team! Her love for animals shows at each and every appointment. She already knows so much but is always willing to learn more. We feel her attention to detail combined with her concern for animals, and friendly disposition will make any pet owner feel confident in trusting her with their pet.

Michelle, R.V.T.

Veterinary Technician

Michelle has been a veterinary technician for 10 years and got her license as a registered veterinary technician in 2018. She has one cat of her own named Kinten who is 6 years old and was found on the porch of her previous job as a kitten. She loves baking amazing treats in her spare time and often shares with the staff. She also loves everything Disney. She enjoys spending time with her family and especially loves being an auntie to her niece and nephew.


Kennel Technician

Marianne grew up here in Castro Valley and has always loved the small town feel of it. She also knew she would always wind up working with animals and has been in the Veterinary Field since 2001. She came over with Dr. B from another hospital in 2013 and had been diligently doing maintenance at the hospital ever since.

Although Marianne loves all animals, her favorite animals are cats. She loves their personalities, even when they’re a little bit spicy. She has her own cat, a Torti named Neko, and while she is a lovable sweetheart at home, she turns into “Mr. Hyde” when taken anywhere else. Outside of animals, she loves movies and books and has an extensive library of both.

Marianne works hard to give the hospital it’s impeccable appearance, by taking care of the plants in the front of the hospital and backyard, cleaning and disinfecting rooms and floors, as well as helps decorate for the holidays. When we get a little shorthanded, she is also able to assist as a veterinary assistant by helping hold animals for vaccinations, or blood draws, calming and relaxing animals while doing so.
