  • Jocelyn Medina
    Customer Care Team

    Jocelyn knew she wanted to be in the veterinary field from the first moment she tended to an injured pigeon. She was only 9 years old when she was exploring the rocks and mountains with her pup, Fifi. She laid her eyes on sad, lonely pigeon sitting on a rock. When she noticed it wasn't flying away, she approached it and knew immediately something was wrong. Young Jocelyn scurried to give the pigeon food and shelter. For a week, Jocelyn tended to the pigeon's wounds until it could finally fly again. Jocelyn was sad that she would never see this pigeon again, but felt joy after seeing the pigeon fly away. This brings her to her caring, and gentle approach with all of our patients here at CAH. Today, Jocelyn lives in Penngrove with Fifi, and recently adopted a Pit bull named Leelah from the Petaluma Animal Shelter. Jocelyn loves her job as a veterinary assistant, and is working towards her goal of becoming a Registered Veterinary Technician.
