Dr. Rufner was very creative and open-minded regarding my Lyme disease and use of all kinds of treatments. He was brilliant and had a range of experience that made for a great visit. The question I brought was not all that difficult, but he handled it well. The paperwork in advance was repetitive and should've been done online to save time for staff to do more important things. The office needs a new investment in software so patients don't have to write their name over and over and staff don't have to transcribe what they have a hard time reading anyway. Single payer would be a good alternative to this insurance mess we have created and perpetuate!!!

Very welcoming staff who were friendly, professional and timely. Dr Sieja was extremely knowledgeable and didn’t try to up sell me on a battery of tests that I did not need yet. Dr Sieja helped me to understand the process of finding out what is ailing me and informed me of next steps. He lied out realistic expectations which was very refreshing.

Kevin is truly an amazing provider and the world needs more people like him. Highly skilled and knowledgeable, and he also has a rare quality I wish more docs exhibited - he truly cares about his patients as human beings. I'm not just a statistic to him and he doesn't just go with the SOP - he embodies medical care the way it should be done: with care, consideration, and using the art of science to treat each person as a unique individual. I am very grateful to have Kevin as my doctor and trust him completely.
