Meet Nathan

I was born in Shreveport, Louisiana and moved to Defiance when I was four years old. I currently live in Defiance and, up until recently, worked at Mercy Health Defiance Hospital in the emergency room and as a house supervisor. I enjoy spending time with my kids and fishing with my dad. I am board-certified and practice in Family Medicine.

Nathan was amazing. He was able to squeeze my son into his schedule on short notice. He seemed genuinely concerned and quick to start him on a treatment so he could start feeling better.

It's always a good experience at this clinic. Nathan Auch is through, listens to and addresses my concerns. He explains everything with a kind demeanor and is very knowledgeable. I will continue going to him until he retires!
