Muñoz, personalize your pet’s veterinary care to ensure they get exactly what they need, when they need it. With over 30 years of combined experience treating various species of animals, you will feel confident that your pet is in caring and competent hands. We offer the time and compassion you want, and the expertise your pet needs.

A Veterinary Technician is a Skilled Nurse for Pets

We are always pleased when a client tells us that they really like and appreciate Dr. Montor and Dr. Diana M. Muñoz. Behind the scenes, they enlist the help of a talented group of pet nurses, which are normally called technicians, in the veterinary field. These technicians perform many of the same procedures as nurses working in the human medical field. Our technicians assist our doctors with surgeries and on their own do dental cleanings, lab work, take x-rays, place IV catheters, and a list of other services too lengthy to list here.

While many veterinary technicians have been trained exclusively on the job (with proper supervision) over many years, others have additionally attended multiyear college programs. In all cases, veterinary technicians, just like human nurses, are the backbone of the veterinary medical team. They are instrumental to Dr. Montor and Dr. Diana M. Muñoz in helping you to keep your pet happy and healthy.

Dr. Diana M. Muñoz

Dr. Diana Muñoz was born and raised in the beautiful island of Puerto Rico. Growing up on the island made her realize the problem with overpopulation and homeless animals. She decided to pursue her dreams to become an advocate for the innocent with no voice.

She received her Doctorate in Veterinary Medicine from Tuskegee University in 2011. Dr. Muñoz enjoys performing soft tissue surgery, dentistry, and internal medicine. She also enjoys educating and encouraging pet owners in taking a proactive approach to preventative medicine. “An ounce of prevention is worth a pound of cure”.

Dr. Muñoz is local to St. Petersburg. She married her high school sweetheart Gino and together they have a daughter named Paola. In her spare time, she enjoys biking and kayaking. She also loves traveling and experiencing new culinary cuisines with her husband and daughter.

Ashley Baker

Office Manager

I am a St. Pete native that has worked in medicine since I was 17: started with veterinary medicine for five years, switched to human medicine, and now back with animals starting in 2021. My favorite part of working with animals is the opportunity to meet every pet's individual personality and work with people who have the same interest in medicine.

I have four rescues; three cats (Luna, Jiji, Sinister) and a yorkie terrier (Abbi). In my free time, I enjoy crafting, spending time with loved ones, visiting nature preserves, reading, and pursuing my interest in psychology.

Lead Veterinary Technician

I started my career in veterinary medicine in 2015, first as a receptionist and then as a technician a year after. I have a passion for marine mammals (especially dolphins) which drove my desire to work with animals. I love having the opportunity to see all our patients and hang out with my coworkers every day. They always make me laugh and help to keep a smile on my face.

In my freetime, I spend time with my three human babies and six fur babies; my cat (Pico De Gato), rabbit (Chubs), and four dogs (Jordan, Ella, Toby, and Ali).

Jesus M. Cruz

Veterinary Technician

My name is Jesus M Cruz. I was born and raised on the beautiful island of Puerto Rico. I’ve been in the veterinary field for exactly 5 years and counting, I’m very passionate about animals. I have worked with a series of exotic species and have had the pleasure to visit some of their natural habitats. 
At a young age I realized how beautiful our planet was, and I decided to journey into The exotic animals world. During my journey I learned that in order to protect ,and care for everything that lives on this planet. We have to first understand it and respect it . That’s why I make sure that pet parents feel comfortable leaving their little furry friends under my care.

Marika Weber

Veterinary Assistant

I’ve always loved animals and wildlife, but my passion for veterinary medicine started after college, when I worked at a sea turtle rehabilitation hospital for 5 years. After this adventure, I decided I wanted to pursue my veterinary nursing degree at St. Pete College, which landed me in St. Petersburg. I love learning and applying everything I do at school to the care of your fur baby!   In my free time I enjoy kayaking, biking or exploring new places. 

Alexis Underwood

Client Care Coordinator

I am a Florida girl, born & raised. I’ve always loved animals more than life itself & getting to meet all the fur babies & their parents is what makes this the best job! My goal in life is to pet as many animals as humanly possible. I have 8 fur babies, 6 dogs & 2 cats: 4 pitbulls, 1 English bulldog, a rat terrier mix, & 2 domestic short-haired cats. They are the absolute light of my life & I would be lost without animals in my life.
