Executive Director

Lilly Villanueva

I always knew that I wanted to work with animals. As a child, I played “cats and dogs” and pretended I was a veterinarian. As my career advanced, I realized it was time to find a way to make a difference in the lives of animals. Once I joined MAH, I knew that I had found the right spot. As Executive Director of MAHE, I am privileged to lead such a strong team that always puts our patients and clients first. My favorite part of working here is being able to build real relationships with people. I want our owners to know that their input and individual needs matter to me. I have 2 cats, Archie and Raider, at home that mean the world to me.

Our Technicians

Brandy, RVT

I have been in the veterinary field for more than 9 years. As a Registered Veterinary Technician, I am able to take on some challenging tasks and better support our doctors. My baby chiweenie, Shanaynay, is my world. I also love naps and flaming hot Cheetos.


Born and raised in Southern California, I graduated from UCLA and decided to pursue a career in the veterinary field. I love being a part of such a compassionate and hard-working team that honors and cares for pets. The team at MAH understands the bond that clients share with their pets. I have two pups of my own at home – Luna and Copernicus.


Growing up in a household full of dogs, I realized my passion at a young age. I always knew that I wanted to work in the veterinary field. After completing my externship at MAHE (PIMA, Veterinary Assistant Program), I was hired on to work with our amazing team of doctors and staff. Mohnacky Animal Hospitals has helped me achieve my passion and further my education.


I was born and raised in Southern California. Animals have always been an important aspect of my life. I have two kitties – Snickers and Fluffy, and the goofiest puppy, Buddy. Working for MAHE has been a rewarding experience for me.


I’ve always had a strong bond with animals. Once I realized I wanted to help animals I started volunteering at animal shelters. I decided that I wanted to take my passion for animals and turn it into a career – I have a Veterinary Assistant certificate and am currently studying to become an RVT. I also have a passion for wildlife and have a wildlife handler’s certification. I can’t wait to help your furry family members and treat them as they are my own. I have two cats at home named Napoleon and Josephene who are my babies.

Our Exam Room Advocates


I truly enjoy working with animals and walking pet owners through the steps of proper healthcare. This job is never boring! There is always something new and exciting to learn. As the lead Exam Room Advocate, I strive to ensure a superior experience in the exam room every time you come in.


Being part of the Mohnacky team is both inspiring and fulfilling. I love having the opportunity to work with clients and their animals, helping give them the most comfortable and positive experience. We have so many adorable fur babies come through our door each day, and being able to give each of them love is the best! I also love going home to give my kitty, “Milo”. and puppy “Banks” tons of love.”


I grew up around animals so being able to come to work every day and help them feel better is the best part of my day! By having a Corgi dog of my own (Tootsie), I understand the importance of being able to take your loved one to a facility that you trust! I am so happy to be a part of such an awesome family!

Our Customer Service Representatives


I love being able to work with animals on a daily basis. I have 2 kitties and a wonderful black lab of my own. As the Lead Customer Service Representative, I strive to provide clients with the best experience possible when they visit. I am committed to Continuing Education so I can help clients safely and properly care for their pets. I am in school to be an Ultrasound Technician and hope to work with animals once certified.
