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


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.


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.


Growing up I was always surrounded by animals from dogs and cats to chickens, goats & cows so I always had a “hunch” of what I wanted to do when I got older. Working at MAHE and meeting all your furry babies is exciting. I love being able to be part of the reason your baby feels better.


I grew up in San Diego and I have always had a passion to work with animals and MAHE has given me the perfect opportunity to do so. I am currently working towards becoming an RVT. I can’t wait to help your animals feel better! I have two kitties at home – Duke and Callie and they are my babies.


I’ve grown up in Southern California always surrounded by dogs, cats, chickens, and horses. I’m currently a student at the University of Arizona getting my undergraduate degree with the plan to attend veterinary medicine school after I graduate. MAHE has given me the most amazing opportunity to get my foot in the door in the veterinary community. I couldn’t be more grateful for this hospital, the people in it, and all the animals I get to help. My animals are everything to me, so I love to help with other people’s babies any way I can!

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!
