Our Registered Veterinary Technicians

Fara, RVT

Working with animals has always been my passion. I started my journey from volunteering at Escondido Humane Society and decided to become an RVT at Stanbridge University, Irvine. After graduation, I decided to travel and gain experience working with less fortunate animals such as feral cats and stray dogs. I came back to the US and had the opportunity to join MAHE and work with an amazing team.

Our Veterinary Assistants


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 in San Diego I always knew I had a passion for animals and when I got older I realized I wanted to turn that passion into a career. Here at MAHE I get that opportunity and I love helping everyone’s furry babies! I recently studied animal law and hope to become a RVT soon. At home I have a dog, Buddy and a tortoise named Dino.


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.


My name is Chelsey and ever since I can remember I wanted to work with animals. Being a vet tech makes me very happy to know I can help heal the hurt animals and bring life back into the sick animals . My passion for the vet world grows stronger everyday, never a dull moment with our furry friends.

Our Exam Room Advocates


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!


I have always had a passion working with animals so I joined the veterinary field in 2015. Joining the MAHE team has been a very rewarding experience for me. I have had the opportunity to learn new things and truly enjoy going to work everyday. I love getting to cuddle with all the fur babies that come my way throughout my day. I am so glad to be a part of such a great team.


I was born and raised in Southern California and grew up with animals all my life. I’ve always had a love for animals. I’ve had pets – hamsters and rats to dogs, cats, and fish. I wanted to take that love a step further and turn it into a career.

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.


Working at MAHE has been a life-changing experience- I love working with our clients and establishing new relationships. I strive to help clients choose the best care for their pets.

Kennel Attendant


Growing up I always enjoyed learning about animals. I loved watching animal documentaries before going to school. Working at MAHE Has been a very satisfying experience and I love taking care of the boarders because of all their unique personalities. I have one dog at home named Zorro and he is my goodest boy.

Client Liaison


My name is Joeie and I am a Client liaison for MAHE. I’ve lived in California all my life. When I was in high school, I was a member of the FFA (The future farmers of America.) This program provided me with all the abilities to train and raise a guide dog for the blind. I have always loved and cared for animals since I was a little girl. My main focus is to provide your animals with the best care possible. Thank you for welcoming me into the Mohnacky Family.
