Dr. Mizera was extremely thorough during my first visit with her and took the time to explain every step of the process. She was kind, had a great sense of humor, and always maintained a positive attitude that made me feel comfortable. Her interpersonal skills were exceptional-she even called me personally to provide updates on my results. She answered all of my questions and those of my husband patiently, kept me well informed, and made me feel confident that I was receiving excellent care. I truly appreciate her compassion, professionalism, and dedication to her patients.

Dr. Mizera is simply the best, from day one to the last visit. Went in with 4 adult children who were worried about the diagnosis and about losing their mom. She answered each and every of their numerous questions and put to rest their worries and anxiety. That was my children. As for me in my most vulnerable moments, she was very kind, relatable and knew her onions. All I know is, it made a big difference in my care. I went through my treatment with ease knowing that God, Dr. Mizera and my whole team were behind me solidly.

It has been a very positive experience for me. The doctor was very kind, friendly, took the time to explain the results, didn't make me feel rushed or judged, and reduced my overall anxiety and stress greatly. The nurses and technicians have all been wonderful. I have a lot of anxiety in general about going to doctors' offices and the doctor and staff really helped relieve that anxiety and reduce my stress. I would definitely recommend to others.
