Michael Schonefeld, Hospital Administrator

Michael joined Long Drive Dog & Cat Hospital in 2022. He’s been in animal medicine for over 25 years and has served in various capacities. His love of animals started while growing up on a farm in South Texas. He raised show pigs while in school and continue to help his dad with cattle on the family farm.

After graduating from Texas A&M University, he continued his work in animal medicine by becoming a practice manager. He has always had animals in his life and will continue.

In his spare time, he works on the family farm and spends time with his wife, son, and chocolate Labrador, Junebug. Since his son got married, he has added a wonderful daughter-in-law and a growing family. Camping and the outdoors is a part of his happy place. He also loves boating and hunting with his family. Traditions and passing down family values are great gifts to give younger generations.

One of his goals in animal medicine is to educate staff and clients so they can advocate for their animals and raise healthy, happy pets. Education is the key to a happy animal life.

Interesting facts: Michael has raised dogs, cats, chickens, emus, cattle, pigs, goats, saltwater fish, rabbits, and birds, as well as having experience in treating large cats, apes and monkeys, large exotics, and Clydesdale horses.
