Colleen Olson is a receptionist at Bay Area Bird and Exotics Hospital, where she began working in June 2025. She holds a Bachelor of Science degree in Medical and Veterinary Sciences from the University of New Hampshire. In 2024, she relocated to the Bay Area, bringing with her a lifelong passion for animals and a strong background in veterinary science.
Colleen’s love for animals began at a young age, starting as a hobby through horseback riding and working at a local barn. Over time, this evolved into pet sitting for friends and family, and eventually, into a dedicated career path during her college years. Inspired by her natural connection with animals and the camaraderie she found among her peers, she became committed to contributing to high-quality pet care. Her favorite part of working with animals is discovering each one’s unique personality.
She first realized she was in the right profession while working at her college’s state veterinary diagnostic lab. The opportunity to collaborate with and learn from veterinary professionals confirmed her desire to continue in the field.
Outside of work, Colleen enjoys spending quality time with friends and family, practicing yoga, reading, hiking, and skiing. Her lifelong passion for horses began at age eight, and she spent four years living on a dude ranch in Montana before moving to California. Colleen loves meeting new people, exploring new places, and is always in search of her next adventure.
