NM Vets

Cristina G. Castro, MDVM


Dr. Castro was born and raised here, in Carlsbad, NM and decided to return home to help take care of the pets in her native community. Ever since Dr. Castro was a little girl, she always had a passion to work with and care for animals. She has been successfully practicing veterinary medicine for over 10 years and has proudly been with Carlsbad Animal Clinic since July 1, 2014. Her personal and professional drive, passion, and love to care for animals is what makes the practicing of veterinary medicine to her, not just a great career, but moreover, a true calling of life that is so very special to her.

In her off time, Dr. Castro enjoys going to church, reading, hiking, and going on ghost town tours with her husband, Marco, and their dog, Ms. Milkshake. Dr. Castro and her husband also love traveling and taking scenic road trips together. She adores spending quality time with Marco, Ms. Milkshake, and their two cats, Mr. Jabari and Ms. Snuggle Muffin. Ms. Milkshake is a lively pet-baby that loves to give kisses and is adored by many. Mr. Jabari is a disabled pet-baby who loves life and does not at all realize that he has a disability. Ms. Snuggle Muffin is a pet-baby that certainly holds true to her name and loves to cuddle and snuggle any chance that she gets.

Dr. Castro sincerely wishes any client and any pet-baby a lifetime blessing of health and wellness.

Trista Mills, DVM


Dr. Mills grew up in Indiana and has been in love with animals from a young age. Her compassion and extreme empathy led her to veterinary medicine where she enjoys doing her best to serve both her patients and their owners through compassionate care. She tends to have an almost kinetic energy at the clinic and enjoys the fast paced atmosphere and the general love the Carlsbad community has for their pets. Her veterinary interests are varied and include medical management of critical care cases, particularly, wound management, exotic animal care and husbandry, and soft tissue surgery. When asked, she says her primary job as a veterinarian is to protect the human animal bond through wellness and promotion of quality of life.

Moving to New Mexico after veterinary school was inspired by Dr. Mills’ fiancé, whom she met during veterinary school at Kansas State University. She’s become particularly attached to New Mexico and loves the gorgeous sunsets and fantastic weather. When not at work, she enjoys running, yoga, cooking, reading, hiking, and travelling when she can. Not only does Dr. Mills love taking care of the many critters she sees everyday through the clinic, she has a wide variety of animals at home to take care of as well including: three dogs, three cats, four horses, six ducks, twenty chickens, and forty-two cows.
