Amanda is a friendly face that is always willing to help!

Erin: Treatment Manager

Erin was a young Petaluma transplant, doing most of her growing up here. We first met her when she started volunteering with us in 2000 at age 15, hired in 2004 and has been with us ever since. She has three cats, senior kitty Phoebe, Scrub who was adopted from Petaluma Animal Services, and Nell who also came from PAS.

Taslynn: Receptionist

Taslynn is a true Petaluman, she and her brother were both born and raised here. At home she has a kitty named Gene who is an adorable wild child and the cutest most lovable puppy Charlie, both were adopted from PASF. Her experience with customer service and history of pharmacy knowledge is an asset to our team. On her off time she is taking classes at Santa Rosa Junior College for the Veterinary Technician Program.

April: Receptionist

April moved to Petaluma in 1993 with her family.  An experienced business owner of various endeavors, she has decided to take a different path in life, joining us in December 2013.  She is very happy to be with us and has enjoyed getting to know each of our clients.  At home she has a dog named Ellie and one kitty, Katie.

Ashley: Receptionist

Ashely is a Sonoma County native who journeyed to Oregon for 6 years while finishing school and returned to California for Cosmetology School, where she graduated in 2012.  In the last two years Ashley realized, after the passing of her beloved dog Tati, she wanted to work with animals.  She got her foot in the door at a pet boarding and care facility where she gained both knowledge and skills in basic pet care.  Following this new path has led her to us and we are so happy she is part of our team.

Sarah: Veterinary Assistant

Sarah joined our team in late December 2017.  She was born and raised right here in Petaluma and graduated from Casa Grande High School.  While working full time, Sarah is also studying to become a Registered Veterinary Technician.  Of course she has fur babies at home, Juneau the kitty and her dog Denali (both after her favorite place, Alaska).  On her off time she enjoys being outdoors – snowboarding, camping, or fishing – but most times you can find her doing her favorite two things: eating or sleeping.  Her positive energy and compassion for animals shines through every day and we are so glad she is with us.

Mystic works hard by hardly working and that is how we like it. She is a love and a joy to have as a part of our family here at Brandner.


RETIRED: Dr. Barry J. Santero, D.V.M: Veterinarian

It is with mixed feelings that we announce that Dr. Barry Santero has retired.  It has been a slow transition over the last two years, yet too quick in many ways.  We truly appreciate his dedication, compassion, friendship, and humor.  He will be deeply missed, but after 40 years of commitment to the community and their pets, he deserves the opportunity to spend more time with his grandchildren, traveling, and supporting his favorite sports team (the San Francisco Giants, of course!).  The entire staff at Brandner Veterinary Hospital wish him the best as he embarks on new adventures. -March 29, 2016
