Growing up in Casper, Wyoming, Dr. Hermilo Gonzalez knew that he wanted to raise his family in Wyoming. He attended the University of Arizona for Medical School, and returned to Wyoming to attend a 3 year Family Practice Residency program in Casper. After completing training, he joined the medical staff at Johnson County Healthcare Center in 1992. He and his wife, Gina have 3 children, and stay very busy in the community. The family enjoys Buffalo, and love the Big Horn Mountains. They participate in many sporting activities, fishing, hunting, bowling, and group activities. They are also active in their local church.

Working in Buffalo is great because our medical staff is very professional. I am proud to work with them.
