Meet Our Vets


Dr. Zach Dielmann

Associate Veterinarian

Dr. Zach Dielmann originally hails from Austin, but has strong roots in San Antonio that he just couldn't escape! With a family history of San Antonio dating back to the 1860's, Dr. Dielmann found himself at Trinity University for his undergraduate degree where he majored in Biology, minored in Spanish, and was an All-American on the swim team.

After Trinity, he worked in the veterinary field, gaining experience at places such as the San Antonio Humane Society and Texas Biomedical Research Facility before he followed in the family footsteps and graduated from Texas A&M with a Doctorate of Veterinary Medicine. Since graduation, he has found a passion for orthopedic and soft tissue surgery, as well as cardiology and neurology.

In his free time, he enjoys spending time with his wife and son, hiking, rock climbing, and generally anything outside!

Dr. Lewis Radicke

Dr. Lewis Radicke is a local San Antonian that has always had a passion for animals, graduating from Texas A&M with a double major in Veterinary Science and Animal Science in 1971, and then receiving his Doctor of Veterinary Medicine in 1975. He has been a prominent figure in the San Antonio veterinary community for over 40 years and opened Lincoln Heights Animal Hospital at it's current location in 1990. Before many of the specialty centers opened, it was Dr. Radicke that provided a wide array of surgical procedures not commonly performed by "general practitioners" that helped LHAH stand out as anything BUT general!


Dr. Radicke has a passion for Southwest and the Four Corners area art that frequently takes him to Santa Fe to support the local art community. Besides Santa Fe, he also can frequently be found traveling the world and enjoying new experiences as well as fishing in many exciting locations.
