Cesar Simon Vazquez, DVM, Owner
Meet Dr. Cesar Simon
Dr. Cesar Simon was born and raised in Madrid, Spain. His lifelong love for both medicine and animals made veterinary medicine a natural calling.
Dr. Simon began his career in the early 1990s, working on a rabbit farm in Spain before advancing to roles as a freelance small animal practitioner. In 1998, he moved to England, where he spent eight years practicing veterinary medicine in both small and large animal clinics, as well as working with the British Ministry of Agriculture.
In 2008, Dr. Simon relocated to the United States, where he has since served in small animal clinics and at the University of Texas. He is certified through the Educational Commission for Foreign Veterinary Graduates and the Texas Board of Veterinary Medical Examiners.
Outside of his veterinary work, Dr. Simon enjoys spending time with his family—his son is his greatest joy. A passionate cook, he loves preparing his famous paella and other traditional Spanish dishes for friends and loved ones. He also enjoys reading, particularly on topics of history, philosophy, and psychology.
Dr. Simon is fluent in Spanish and conversational Italian and shares his home with his partner Lydia, a ball python named Manolo, and a cat named Basil.

Shaiel “Noa” Caldiero
Receptionist
Born in Argentina and raised between there and Houston, Texas, Noa brings a warm, bilingual, and “crazily caring” approach to the front desk. With two years of hands-on kennel experience under her belt, she recently brought her passion for animal care to her role as a Receptionist. For Noa, the best part of the job is interacting with our wonderful clients and getting to see all of their furry “babies” every day. She takes pride in keeping the clinic running smoothly, handling everything from opening and closing duties to processing files with a smile.
Life Outside the Clinic
Before joining the veterinary field full-time, Noa gained valuable customer service experience working at Jamba and Subway. When she isn’t at the clinic, she loves spending quality time with her close-knit family—including her mom, dad, sister, and grandma—especially during their Sunday outings. She also dedicates her free time to volunteering and serving at her church. She is a big fan of playing video games with friends and taking herself on independent solo dates to go shopping or see a movie. While she grew up surrounded by lots of cats and two sweet Chihuahuas, she treats every pet that walks through our doors as her own!
Leah Fowler
Veterinary Technician
Leah Fowler is a dynamic presence at Pet Clinic on Bellfort, where she has been a key part of the clinic team since July 2025. With three years of total experience in the veterinary field—spanning both customer-facing receptionist roles and direct animal care as a technician—Leah brings a well-rounded and deeply empathetic perspective to her work. Unsurprisingly, her absolute favorite part of the day is getting to bond with all the dogs and kitties that come through the doors, as well as collaborating alongside her clinic teammates.
Born and raised right here in Houston, Texas, Leah holds a high school degree and spent years working in the service industry and at a boutique before transitioning her customer care skills to the veterinary world. Outside of work, she is a proud dog mom to her beloved doodles, Annie and Alfie, whom she describes as the absolute best babies in the world. When she isn’t at the clinic, you can find her traveling, shopping, catching up on well-deserved sleep, and spending quality time with her boyfriend, friends, and family. She brings such great energy to the team that she even has her own signature clinic sign-off: “Peace, love, Bellfort!”

She is also a strong swimmer, enjoys painting with watercolors, and is an avid reader who is on track to finish an amazing 100 books this year!

She originally joined the clinic family in March 2024, and after a brief relocation to Wisconsin, happily returned to the team in April 2026.

Born in Yoro, Honduras, Kassy moved to Houston at the age of ten. She built her veterinary career from the ground up, starting out as a kennel technician and working her way up to her current role. She is also proudly Fear Free Certified, ensuring every visit is as stress-free as possible for her patients. When it comes to animal care and customer service, Kassy’s philosophy is simple: it all comes down to “patience and care.”
Outside of work, Kassy’s “kids” are her five beloved pets: Apollo (a Malinois mix), Spike (an Akita), Sapphire (a Siamese cat), Opal (a Domestic Shorthair cat), and Ash (a Pittie mix). She is fully bilingual in English and Spanish, loves country music and all things Western, and spends her days off enjoying road trips, traveling, and attending church.
