About Us

Dr. Allen Hallada

Practice Owner/Veterinarian

Dr. Hallada grew up in rural Wisconsin.  He was a biochemistry major at the UW-River Falls and recipient of the 3M Research award.  He completed his doctorate work at UW-Madison School of Veterinary Medicine where he received the annual award for Proficiency in Small Animal Surgery.

Dr. Hallada was a partner in a multi-doctor mixed animal practice in Winona, MN where he worked on a variety of different animals including exotic large animals such as zebras and reindeer.  He worked for the US Fish and Wildlife Service studying migration patterns of Paddlefish and Sturgeon.

Following his dreams to live in the mountains and do public speaking, he moved to Sun Valley, ID where he lived for the next 7 years.  He spoke throughout the country on delivering outstanding customer service and effective communication in the workplace.  He was also a veterinarian to many celebrities that lived in the area.

Dr. Hallada purchased Mesa Veterinary Hospital in August of 2003.  After performing major equipment upgrades he is finally achieving what he originally set out to do from the time he graduated from veterinary school, to provide a level of veterinary service to companion animals that we humans have.  He continues to perform surgeries, dentistry, and is a strong advocate of wellness in pets.  He is an Elite speaker for Pfizer Animal Health and teaches other veterinarians how to perform safe and effective anesthesia and pain management in pets.

Away from work, Dr. Hallada enjoys downhill skiing, golfing, and biking.
