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’s 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.

Our Exam Room Advocates


After completing my undergraduate degree, I found a calling in veterinary medicine. I wanted to work with the doctors and the clients in a way that facilitates the best possible care for our patients. As your Lead Exam Room Advocate, I get to do the work that I love, ensure quality patient care, and provide an amazing client experience.


I enjoy meeting all of our clients and their furbabies! I love providing them with the best care and I strive to make all of our clients feel like they are family.

Lacie – Lead CSR

I have had a passion for animals since a very young age. I’ve been working with animals since I was 15. Working at MAHVs a dream come true. Being able to provide an exceptional experience for you and your pet makes each day better! I have 2 blind kitties and a scruffy dog of my own that drives my passion to see others just as happy about their furry pawed family members!


Born and raised in Southern California, I find happiness in making connections with our clients and their furbabies. As a fellow pet owner myself, I treat every pet that comes through our doors as if they are my own. I enjoy treating every client as family, with welcoming arms and a huge smile.


I was born and raised in North Texas. I have loved animals my entire life and getting to work with them is a dream come true. I have 2 dogs of my own – a Dalmation named Pongo and Bubba the Great Dane. I love being able to provide exceptional care to you and your furbabies!
