Technician Assistant

My name is Marshall. I’ve been lucky enough to work at Stone Ridge VMC for the last 2 years. Working with animals has been a life-long dream of mine and thanks to Stone Ridge, I’m living my dream.

A little about me: I have a beautiful wife and 3 crazy boys ages 1,2, and 3… talk about having your hands full! The family doesn’t stop there: we have an 11 year old pit mix, Killer AKA Bubba AKA Handsome Old Man. Then there’s Tuna, a 7 week old Chihuahua. Wink (he has one eye) is our 9 month old cat. Last but not least, we have 5 chickens. Sometimes I think, “Are the kids the crazy ones or are we?”

The years prior to my joining the Stone Ridge team, I was dedicated to martial arts training and worked in my family business of teaching martial arts. Since selling the business, I’m beyond happy to continue my education in what God called me to do- caring for animals. An added bonus is I get to serve on an amazing team.  I’m grateful to learn from and work alongside amazing professionals at Stone Ridge and feel blessed to be able to care for the furry members of your family.


Technician Assistant

Hi guys! My name is Lidia and I am currently a senior at Sam Houston State University, eager to pursue a career in veterinary medicine. I am originally from Houston but currently reside in Conroe because it’s closer to school.

I started my career in Vet Med about a year ago, starting as a CSR at an emergency hospital and later landing a job at Stone Ridge VMC. My favorite aspect is often learning more and more about the industry and also assisting Spanish-speaking clients! I’ve always told myself I want to be a voice for the fur babies that can’t speak for themselves and it’s even better when I’m able to help my community while I’m saving lives.

I dream of becoming a veterinarian that works with both large and small animals. I would love to specialize in either reproduction or general surgery in the near future. However, after graduation, I am interested in pursuing a masters program in business as I intend to build and operate my own clinic in the future.

In my free time I love to sing, go out to dance, and binge watch shows till I can’t anymore! My favorite dishes are anything in tomato-based sauce, anything smothered, and rice! I taught myself how to cook when I left home and have fallen in love with it.

At home, I have 4 fur babies- 2 cats and 2 dogs, so I have my hands full! I am the youngest of 4 siblings, so you already know I am the crazy child as well.

Client Care Specialist

I’ve always loved working around animals and being able to help people.

My favorite part about being a ccs is the interactions with the owners and their animals and being able to help any way possible.

I have 2 dogs, one is Stella Rose who is a Husky Mix and she just turned 2 years old. Also, I have Bailey who is a silver lab and just turned 1. They are both very energetic dogs who love the zoomies.

I have 2 brothers and an older brother named Tyler who is a year and a half older. He is 25 and has a younger brother named Nathan who is 7 years younger, and he is 17. My dad works in the oil and gas industry and my mom is a teacher.

Something interesting about me is that I am French but also, I have a little bit of polish.

Something on my bucket list is to go skydiving. In the next 5 years I would like to have a house built.
