"Extremely nice stuff. They make you feel welcome. Dr. Gunia is a highly qualified professional that gave me reassurance everything is going to be okay. She is very kind and the best, she took the time to explain my options. Very pleased with my first time appointment." -Marie

"Dr. Gunia is hands down the best surgeon I’ve ever had. She was extremely personable and caring, and explained everything to me in “regular person”-speech, not doctor lingo. She ended up doing a partial mastectomy in my R breast, removing a large lump which was thankfully not malignant. I will definitely use her again if I have any further issues with my breasts. I HIGHLY recommend her as a surgeon and a breast doctor!" -Juleah
