Dr Walker diagnosed my father’s Pancreatic Cancer in the very earliest stages. We were able to have three good years with our dad as he battled his cancer.

I definitely recommend him to anyone who is in pain and needs to know why! His assistant Kristen is incredible! When dr.

The front office staff were friendly and welcoming and most of the back office staff were just as lively. Not one person was short with me, impatient or dismissive of me. I’m grateful my primary doctor sent me here."
