Get to know our veterinary team!

Dr. Diana Walker, DVM

Owner & Veterinarian

I attended Texas A&M College of Veterinary Medicine and Biomedical Sciences and have been practicing veterinary medicine since 2013.

Two of the biggest parts of my days consist of client communication and patient care. Being able to provide gold standard communication and care to every client that comes through our doors is something that is valued very highly for both me and my team. I take pride in being able to know how to research new techniques for treatments to common problems and being able to educate a pet’s owner on what is going on with their little, and sometimes not so little, bodies and how we can best treat whatever ailment they are facing. I appreciate being able to build rapport with the family members that entrust me with their pets and being able to advocate for those patients every day.

When I am able to enjoy time away from the clinic, I enjoy baking quite a bit. I also enjoy spending time caring for my own animals which include a rottweiler, 2 dachshunds, chickens, and our very own beehives!

Dr. Kristie Ikels, DVM

Veterinarian

I received my veterinary degree from Texas A&M College of Veterinary Medicine and Biomedical Sciences and have been in practice since June of 2021.

Times have changed and pets are not just pets anymore, but a part of the family. We are entrusted with these family members here at Bryan Animal Clinic daily. Being able to provide even a small comfort to their owner is something that I am proud to do for each patient in my care. It can be something as simple as a reassuring word, or knowing that I will have a technician checking in on their pet overnight, but every time I can make a pet parent more confident in the care their pet is receiving it makes my heart smile. Building these kinds of relationships is a big part of the job, and I love being able to do so in this community. Some of my favorite aspects of this field include: Surgery, Ophthalmology, and Large Animal Medicine and I am so looking forward to being able to add to my knowledge bank as I continue on with Bryan Animal Clinic and Veterinary Medicine.

When I am not busy with my own fur babies, I like to travel, spend time with my family, read, and bake!

Dr. Maria Melgar, DVM

Veterinarian

I graduated from Texas A&M University College of Veterinary Medicine & Biomedical Sciences and started practicing in 2025. I’m so excited to be part of the Bryan Animal Clinic team as I begin my veterinary career.

What I enjoy most about being a veterinarian is the chance to make a real impact—both in the lives of animals and in the relationships I build with clients. I love getting to know people and their pets on a personal level. Learning about different cultures and how people care for their animals is something I find fascinating and deeply rewarding. Even early on in my career, it’s been incredible to see the trust clients place in us to care for their beloved pets.

When it comes to patient care, I believe in compassionate, individualized treatment. I take the time to listen, communicate honestly, and work as a team with each client to find the best path forward. My goal is always to build trust through clear, supportive conversations—because that’s the foundation of great care.

Right now, I’m especially interested in emergency medicine. I enjoy the fast pace and the opportunity to make a difference in critical situations. I’m also passionate about community outreach and education. I believe in making veterinary care more accessible and supporting pet owners with knowledge and resources.

Outside of the clinic, I love playing video games with my friends, spending time with my chinchillas, dogs, and cat, and going to K-pop concerts with my best friend. We travel to different cities for shows and love trying new foods along the way. I’m also a big anime fan and enjoy going to conventions when I can. These hobbies help me relax, recharge, and stay inspired!

Dr. Alyssa Sauer, DVM

Veterinarian

I graduated from the University of Illinois College of Veterinary Medicine and started practicing in 2025.

The thing I love most about being a veterinarian is getting to be a part of the special bond between animals and their families. Our pets are part of the family, and it’s a privilege to be trusted with their health and care. I’m grateful for the relationships I’ve formed and for being there through both the joyful moments and the challenging ones. And of course, the tail wags and soft purrs are a wonderful bonus too!

I believe one of the most important aspects of patient care is good communication. Our patients don’t have voices, so it’s my utmost priority to advocate for them and provide the best care possible. We can learn so much from their body language, and it’s important to make sure they feel comfortable and have a positive experience while in our care. I also truly value client education—not just providing information, but building a partnership with pet owners so we can make decisions together.

My interests in veterinary medicine include nutrition, neurology, surgery, emergency medicine, and internal medicine. Outside of the clinic, I enjoy spending time with my family, traveling, cooking, and watching Aggie football!
