I have deviled osteoporosis after radiation treatment for rectal cancer. We discussed the goods and the bags of taking medication, I was particularly worried about GI problems as it has taken me three years to recover from chemo and radiation, three years of nausea, diarrhea etc. Dr Z was very sensitive about my concerns and we agreed on a treatment plan after a comprehensive discussion. I felt very reassured and confident.

Dr. S always listens to my concerns and takes action right away to solve them. If it wasn't for him I wouldn't of found out about my thyroid cancer. He listened to me about my worries and went above and beyond for me. He ended up referring me to my surgeon and even though it wasn't his field of expertise he trusted to send me to the right place. I am so happy I have Dr. Z and I always look forward to see him.

Doctor Zawidniak is patient, easy to talk and a person who makes a sad situation bearable.

5 out of 5 stars

Dr. Zawidniak is approachable and clearly very knowledgeable in his field. Takes time to follow up by asking questions and explains the why or why nots to different treatments. Pretty responsive through the online messaging portal when I've had issues. The staff I've interacted with have all been polite and professional.

Dr Zawidniak is knowledgeable and professional, and, important to me, easy to talk to; a good doctor and a nice guy.

5 out of 5 stars

Dr. Zawidniak is very down to earth. Very easy to talk to. He explained my issue carefully to me to make sure I understand, which I think it is one of the most important things for patient to understand their illness especially now Dr is given 15 minutes only to spend with us, but he was able to accomplish all that in that time frame in a very kind and understand way without rushing me out the door like sadly many doctors are doing working under pressure
