Erin Alexander, DVM, Partner

Del Rio Veterinary Diagnostic HospitalDr. Alexander enjoys helping people through sharing her love of medicine and animals. Dr. Alexander grew up in Devine and graduated in 1993 from Texas A&M with a Bachelors Degree in Animal Science. After graduation, she worked at San Antonio Livestock & Rodeo. She was responsible for compiling show results, writing press releases, and coordinating college interns. After a year in San Antonio, Dr. Alexander returned to Texas A&M and went on to receive her teaching certificate. She taught 8th grade science at Spring Branch Middle School in Houston. After three years of teaching, her love of animals and fascination with medicine could not be denied. Her journey continued from teaching to becoming a veterinary receptionist and then a technician, which served as a great training for her lifelong career choice as a veterinarian.

She graduated from Texas A&M School of Veterinary Medicine in 2005 and went on to practice in a mixed animal veterinary hospital in Fayetteville, NC. Like all true Texans, Dr. Alexander found her way back to Texas in 2006 and has not left since.

“I’m very much looking forward to settling in Del Rio. I know the city is looking for more veterinarians, and I’m ready to help,” states Dr. Alexander.

When not at the veterinary hospital, Dr. Alexander and her husband, Jay, can be found in Rockport fishing for trout or redfish. Dr. Alexander and her husband, Jay, own four dogs, three hunting dogs and one enthusiastic heeler mix rescue named Rose.

“Talking to pet parents about pet care is so important. I like to take the time to listen and communicate with clients, which they appreciate,” says Dr. Alexander. “Visiting with my clients and solving their pet’s problems is why I’m a veterinarian.”

Del Rio Veterinary Diagnostic HospitalIn 2005, Dr. Whitten earned his degree in Agribusiness with a minor in Economics from Texas A&M University. After a brief time in the banking industry, “I knew I wanted to go back to my roots which was being with animals. I grew up on a ranch in Eldorado, Texas, and animals were a part of everyday life. I missed it. So in 2009, I went back to Texas A&M as a veterinary student.” After graduation in 2013, Dr. Whitten worked in a mixed animal practice in South Texas.

At DVDH, Dr. Whitten has access to cutting edge veterinary medical equipment. The on-site diagnostic tools allow him to quickly and affordably diagnose and treat his patients. “Getting these animals well and out of pain quickly means a lot. It’s the reason why we are here,” states Dr. Whitten.

Dr. Whitten is a member of the American Veterinary Medical Association and the Texas Veterinary Medical Association. When not caring for animals, Dr. Whitten enjoys family time with his wife and sons. His hobbies include: hunting, fishing and golf.

“Opening my own veterinary hospital has been a dream of mine,” said Dr. Whitten “and when the opportunity to open a veterinary hospital in Del Rio was presented, I knew it was right.”

Dr. Whitten, his wife Amy, and their three sons, Walker, Barrett, and Reed, look forward to building a life in Del Rio. “Building long-term relationships with the people in Del Rio and the border region is something I look forward to.”
