​Director Doctor of Veterinary Medicine

Satoru Yonezawa

They are children with a life of the same weight as us in a small body. I would like to face the attacking demons of disease, study hard every day with a strong will, and provide daily medical care without forgetting the perspective of the owner and the importance of one life.

The origin of the hospital name is   origin = atom = "atom".

I want to help sick animals.

That is the origin of Atom.

And I would like to make it a hospital where staff who share that origin gather together.

I want to help sick animals, especially animals that cannot breathe due to respiratory diseases.

With this in mind, I have continued research, developed various surgical treatments, and treated many children.

I would like to play a role as a family doctor, such as various preventive medicine, internal medicine, surgery, and various medical treatments.


We appreciate your continued patronage.
