Brenda Jarillo


Brenda Jarillo, Veterinary Technician Assistant
(she/her/hers)

Brenda’s Bachelor of Fine Arts, earned with high honors from C.W. Post of Long Island University in 2002 lends itself more to her personal time than professional. She promptly left behind the photography studio for a career in hospitality. The ensuing years found her managing restaurants and helming bars in Brooklyn, San Francisco and Boston. Seeking a way to combine further learning with interests she enjoys; Brenda was inspired by her lifelong love of the four legged and furry to pursue a new area of hospitality here within our community-oriented veterinary environment. Her free time finds her buried in innumerable pursuits of creative craft, consuming untold volumes of cheese, biking, canoeing rain or shine with her partner, and napping with her two elderly pups.
