Dr. Donnie Hoff

Owner, Veterinarian

How long have you been practicing?
Since 2013

Where did you go to school?
Colorado State University

What do you pride yourself in when it comes to veterinary medicine and/or taking care of your patients?
I take great pride in effectively communicating with clients about their pet’s health concerns and needs. Being able to convey complicated disease processes, treatment options, and patient prognosis in a way that makes sense to each individual client is of vital importance to ensure each pet’s well-being.

What do you like to do in your free time?
I enjoy carpentry, outdoor activities such as hiking, playing musical instruments (poorly), and spending time with my non-judgmental family members: Camber the cat (head honcho of the household, quite judgmental actually), two Bassett Hounds, Mayday (the 3-legged angel) and Amelia (the boss, 2nd in command, thinks she is 1st in command), a duo of tree frogs, and two sulcata tortoises, Morla and Morticia.

Veterinarian

Practicing four years

Where did you go to school?
Kansas State University College of Veterinary Medicine

What do you pride yourself in when it comes to veterinary medicine and/or taking care of your patients?
Taking care of patients when they need me the most gives me the biggest sense of pride as a veterinarian. I enjoy working with all of my patients, from their first puppy visit to their senior years. Working out a complex case with my team gives me a great feeling of accomplishment because it allows me to foster the human-animal bond. Becoming a veterinarian took a lot of hard work, and it is my pleasure to serve my community and their pets.

What do you like to do in your free time?
On my free time I enjoy traveling, browsing social media, hanging out with my pets, and cooking. A perfect day would include being home with my boyfriend, Scott, planning our next getaway.

Jd Messineo
Practice Manager

I have been a part of Castlerock Pet Hospital for the last 12 years. I went to Texas A&M Central Texas and graduated with a Bachelor’s in Business Management. I have always worked closely with animals. I love my job. I couldn’t even think about doing something else. I take pride in creating an environment where people feel comfortable leaving their 4 legged loved ones with us for quality and loving care. I treat everyone’s pets like they are my own. Vet med is very special to me and very close to my heart. I love helping pets and people. I love seeing people’s faces when they pick up their pet from us. They are so happy to see them. It makes me feel good that we helped make that happen. I also take pride in knowing what the best products are out there for us to use and know everything about them. In my free time, I love to ride dirt bikes. I race 80-100 mile enduro races about once a month. I live on a 100-acre ranch. We have a working goat dairy and have just about every animal you can think of.

Makayla Urbantke

Veterinarian Technician

I have been practicing for 5 years and still learning new things every day. I started going to online school at Cedar Valley College this year and will be achieving my Associate’s in animal sciences. I take pride in educating clients on what is best for their pets so that they can take the absolute best care of their babies! Though I am still learning new things myself, I love putting my new knowledge to use. In my free time, I enjoy lying on the couch, snuggling up with my dogs, and watching a good movie or TV series I’m currently binge-watching. On the weekends, however, I love to spend time with my friends and family whether it be out for dinner or at the bar for a good night of dancing!

Veterinarian Technician

I am a Vet Tech at Castlerock Pet Hospital. I have a German shepherd named Roxy and a Crested Gecko named Arty. I have been working with animals since I was 15 years old, where I started out in the Kennels taking care of the animals. Though that I had gained the knowledge and experience to become a vet tech. I have now been a Vet Tech for 4 years. I love getting the chance to work with animals every day, and making a difference in the lives of our patients and clients. Also, I like to ensure that our clients leave feeling informed and at ease after every visit. I believe in giving a personal touch in the caretaking of the patients so they are comfortable during their visits. My hobbies include photography, hiking, and listening to live music.

Meredith Solis

Veterinarian Technician

I got started in the vet field after a friend recommended it to me. I have never looked back I went to a private business school, but clearly that wasn’t my calling. I have 3 dogs a cat and a fish. I love my job because I am rewarded with giving our pets a better quality of life. My tails consist of MJ, my Black Mouth Cur, Hercules, first toy poodle, Ziggie, second toy poodle, Hades, my adorable black cat, and last but not least my fish Percy. I love that my passion for animals has led me to a great place. I get to love, save, cherish, and honor beautiful animals. Pets are my passion!

Grace Whitman

Veterinarian Technician

Round Rock High School

I take a lot of pride in being there to help ease the patient or owner’s anxiety and provide them comfort. It’s an honor getting to know all the animals and seeing familiar faces. I’m always learning something new from our patients.  

If I’m not with my Cat Gus or sleeping, I’m out playing volleyball with my friends or studying languages I want to learn and improve on. Currently, I’m studying Spanish and continuing to study American Sign Language. 

Amber
Amber Goodwin-Tillis

Veterinarian Technician

My name is Amber and I have three dogs. I foster, rescue, and rehome dogs whenever I have the opportunity. I have been practicing for just under a year however I had the wonderful opportunity to work with a veterinarian in Mexico at her practice every summer for about 4 years as a teenager. I pride myself on the passion I have for this field. I love that every day is a learning opportunity. Of course, working with animals is my favorite part of my job, but I love working with their owners just as much. Having an animal and its owner leaves happy, educated, and content is just one of the many great things about being a Vet Tech. In my free time, I enjoy rock climbing and hiking trails with my German Shepherd Zoe.

Nichole Hoff
LVT

I went to PIMA Medical Institute Las Vegas, NV campus. Although I take great pride in caring for all of our patients, I have a special soft spot for geriatric pets with chronic medical conditions. I tend to gravitate towards the white-faced, old-timer, arthritic canine, and spicy senior cats in kidney failure or diabetic most. On the opposite end of the spectrum, I have a keen interest in neonatal kitten care and husbandry. Having experience in the veterinary field of not only general practice but specialty medicine and emergency, I take pride in sharing the knowledge and tricks I have gained over the years to clients and colleagues alike.

Now that I’m out of the desert I have started to dabble in some fruit and vegetable gardening. Was drowning in cantaloupe, okra, and cherry tomatoes last year, definitely planning better for this year. I enjoy cooking and trying new recipes from Pinterest. Love summer weekends at Lake LBJ with my in-laws, boating, hiking, and exploring new areas in Texas. Squished on the couch under two basset hounds and our cat is probably where I spend too much of my free time though, but love my three and four-legged kids.
