I think Dr. K is absolutely professional and compassionate. I didn't have a clue what this appointment entail. I call him Dr. K welcomed me and assured me I was in the right space at the right time. He's pretty cool.

I'm not sure what I would do without Dr. Kubiak.

I've travelled extensively since my initial cancer diagnosis 4.5 years ago. Kubiak is the most knowledgeable in the latest treatment potions, and proactive in sharing these treatment options with me of any of the five doctors I've seen since my initial diagnosis.

Dr. Kubiak is an extraordinary physician. My work took me all over the US. I've seen six doctors at different facilities since my diagnosis. Dr. Kubiak is far and away the best... He understand the latest protocols, is professional, kind, encouraging & funny!

Because he persisted at getting the insurance to approve my current medication, my condition has improved and not on a steady decline.

I've seen no fewer than seven doctors over the last three years because of my travel schedule. Dr. Kubiak was very impressive. He listened carefully and explained things well without being condescending.

All good.

Main issue is lack of continuity with provider, having a new provider nearly every visit, and now being informed that I will have to travel to Billings for future apppointments.
