Dr. Sornson knew I had several other serious problems going on associated with my lymphoma treatments and asked whether I would prefer postponing my 4 MOHS surgeries scheduled for that day. I decided I wanted to go ahead as scheduled, but I truly appreciated that he offered me the option. Very caring.

Dr. Sornson is a wonderful doctor and an extremely kind and empathetic person. His bedside manner helps patients feel comfortable. He is enthusiastic and energetic despite a busy schedule and never makes you feel like you are a burden or inconvenience. I have seen him twice for postpartum skin issues, and I always feel like I can trust him 100 percent.
