Maycie, RVT

I was born and raised in Southern California and love the outdoors. Working with animals is my passion. I started out as a kennel aide and worked my way up to Registered Veterinary Technician. I have a one-eyed cat named Toulouse and 2 dogs named Carson and Anza.


Trust is a large part of the veterinary experience and I strive to be a trustworthy individual who will provide the best possible care.


I want to meet all of the fur babies! My days are made so much better with each tail wag or slobbery kiss. I love this field and am lucky to be here.


Following in my father’s footsteps, I want to continue our family‚Äôs legacy and provide the excellent care that all of our customers, both two and four-legged, have come to trust.


I have worked in the veterinary field for the past 12 years but I have been an animal lover my entire life! I am presently pursuing licensure as a Registered Veterinary Technician- keeping pets healthy and happy is my goal.
