Patient Comments (6)
we have been accustomed to rushed appointments while other patients are given adequate exam time. In today’s appointment you treated our daughter without care and without patience and you were rude. You physically showed that you were annoyed by Anabella. My daughter was simply asking questions but, you belittled her and at the same time you offended me. Anabella is only five years old and as far as I know most five year olds are curious and talkative.
It was such a sad day for us. The lack of compassion for our disabled children was the worst we have ever experienced. Dr. Gerontis couldn't have and didn't want to be bothered with us. She didn't so much as grimace throughout our visit. If you have a disabled child you couldn't be in worse hands or a more wrong place than her office. Her bedside matter was atrocious-probably the worst that we have ever experienced. Doctors in pediatrics are expected to treat the whole child!!!

My son has been a patient of Dr. Gerontis for 19 years. She is the best! My son was born prematurely at 25 1/2 weeks and we have been a patient of hers since the NICU. She is very professional and always takes the time to explain everything to us so we understand what is going on. I Highly recommend Dr. Gerontis, couldn't say enough good things about her.

Dr. Gerontis is an excellent doctor. Her office is beautiful and her staff are a pleasure to work with. They go out of their way to help accommodate you. They work hard and don't put up with bully parents (Sara). It is refreshing to see how they put the patients first
It was great. She knows her job made me feel comfortable. So far she's the only person I go too.

Terrible. Her staff is terribly rude and I(and my friends and family), will NEVER return. I was hung up on and told my family had bad attitudes. Horrible experience... Sara Walther
