Our Veterinary Team

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 1860s, Dr. Dielmann found himself at Trinity University for his undergraduate degree.

Eventually, he followed in the family’s footsteps and graduated from Texas A&M with a Doctorate of Veterinary Medicine in 2018. Since graduation, he has found a passion for orthopedic and soft tissue surgery, as well as cardiology and neurology. Initially, he worked at a small animal practice in the Alamo Heights area, but he always enjoyed the more emergent cases that walked in the door.

After 4 years, he decided to take that medicine to the emergency field and try to help patients that had nowhere else to turn.

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

Dr. Alan Mosley grew up in South Texas and has returned home to work with us at Hill Country Animal Emergency Hospital. He started life in Corpus Christi until he left to go to Texas A& M for the best 8 years of his life, graduating from veterinary school in 2003. Since graduation, he has practiced in multiple locations across the southern United States and even spent a couple of years across the pond in the United Kingdom after marrying his beautiful limey bride. Although he got his start working in mixed animal practice, he soon realized that he was more fulfilled helping clients and pets at night with their emergencies.

Dr. Mosely really enjoys snowboarding and walking the golf course, without being very good at either. Usually, he spends his free time working on his honeydew list or watching his young daughter, trying to keep her and Baloo, the family’s Australian Shepherd, out of trouble.
