This man should not be working with any children. My 25 year old son still has a phobia of dentists after his experience with Derenzo. He screamed at my son when he was a toddler and forcefully restrained him and tapped on his teeth with a large dental tool because my son didn't open his mouth wide enough. My daughter witnessed all of this as she was having a cleaning in a chair near him. Back then, parents weren't allowed in the exam and procedure area with their kids. I could hear my son screaming and crying from the front waiting room area. I filed a complaint and nothing was ever done. I highly recommend taking your child ANYWHERE other than here. This man is barbaric and shouldn't be allowed near any children. read more

I took my 7 year old son to visit George Derenzo, DDS today after waiting three weeks for an appointment. My son is afraid of the dentist because he's had to have a couple of teeth pulled. When the dentist went to exam Chance, he put his hands up to ask him what was he doing? The dentist immediately said, 'I'm not taking this case. I'm not doing this'. And asked us to leave. He was totally unprofessional. Once I complained, and called him an ass he threatened to call 911. I told him to go right ahead and I'll be right there when they came. His staff must be used to it because not only didn't they call but acted like they understood his behavior. When we got back into the car, Chance asked if he did anything wrong. I told him no! It's ok to be afraid. If you have a question, ask it. He also asked why they were calling the police. I told them because they didn't like what I said. read more

They recommend my child have a root cannal. She did with an the dentist they recommend. I was they were the ones to put the crown on. I have to take off of work without pay for the appointments. I made an appointment the office canceled. Made a second appointment the office canceled. Finally we when to the third appointment. The dentist just looked in her mouth and told me they do not do this type of work. Why then did they let me make on appointment for a crown if they were going to do it. read more

DO NOT TAKE YOUNG KIDS HERE!! Let's just start at the beginning... I took my daughter to *my* dentist for her first cleaning where I found out she had two cavities. They told me I should take her to a pediatric dentist to have the work done. I was reluctant to take my 3 year old daughter to Dr. Derenzo based on the reviews but sadly, this was the only pediatric dentist in Delaware that my insurance accepted. I figured I would make my own assesment before going to Aston, PA (which was the next closest in my network). So I made the call. The first time I called I was put on hold and while I was holding, someone picked up and accidently hung up the phone. So I called back. When I said I was just holding and got disconnected the girl told me I hung up on them. I told them I didn't and she said that I did. (Way to argue with a new patient - First Strike) So I brought my daughter in for the visit. I knew she had two cavities so they needed to take X-rays. The woman who did her x-ray was not very impressive. She SAID the right things but she was so monotone and insincere. She was so obviously annoyed that my 3 year old daughter wasn't staying still. She had zero skills on how to get a toddler to cooperate. Dr. Derenzo came in the room when the x-rays were finished. He was not personable at all. I think he said maybe 3 words to my daughter. He just told me she had two and a half cavities and that they would try to do them in office with nitrous oxide since she had a hard time keeping still in the seat. The lady who did the x-ray promised my daughter stickers which she did not get. I left there feeling extremely uneasy. I told my daughter we would need to come back to the dentist for her cavity. She asked if we could go to the other dentist. I told her we couldn't and she got upset and said she didn't like the new dentist. (Neither did I sweetheart - Strike Two.) So the time is here! Cavity Fill Day! We pull up to Dr. Derenzo's office and right away my daughter says "NOOOO MOMMY! NOT THIS DENTIST!!!" Great - Can't wait to start this. I do my best to be upbeat and assure her that this dentist is great and nothing will hurt. We get to the back and the dental assistant puts the nitrous oxide mask on my daughters face. No warning. No coaxing. Just puts it on her face and walks away. My daughter freaked out and took it off. The lady just stood there looking at my daughter and looking at me like there was something wrong with my daughter. SHE IS 3 YEARS OLD! YOU JUST PUT A FOREIGN OBJECT ON HER FACE WITH NO WARNING! Moron! So I had to get up and coax my daughter and convince her to keep it on. Just then Dr. Derenzo comes in and they lay the chair back. My daughter covered her mouth. She was freaked out by this point. They both had the most annoyed looks on their faces. Neither one of them tried at all to calm her down and get her to open her mouth. Instead the assistant held my daughters face while Dr. Derenzo pried her mouth open with his metal tool!!! I sat there in horror. It took every ounce of me to not freak out and snatch my daughter out of the chair. THEY DIDN'T EVEN TRY TO GET HER TO OPEN HER MOUTH! They just forced it open!!!!! She was so upset. I was so upset. When he was done looking in her mouth my daughter was crying and jumped off the chair and ran to me. Dr. Derenzo said our next step is to give her a shot in her butt to sedate her and that she would have to be strapped down. Sorry dude. This was Strike Three. I left there, put my glasses on and quietly cried the whole way home. I cannot believe that this place is a pediatric practice. They have ZERO skills with young children. Please - do yourself a favor and do not take your children there. read more

George Derenzo should NOT be working with children yet runs a pediatric dentistry! At our first visit he criticized my parenting. At our second visit for my son's first procedure, by the grace of God, we were seen by his associate for my son's 1st tooth extraction and crown. She was amazing and his recovery was immediate. Unfortunately, she only works Mondays and at our third visit, Dr. Derenzo yelled at my son, was impatient and rude. He said, to my son and I quote, "You aren't going to keep asking me questions about what I am going to do and if it will hurt. You're tooth hurts right, well I am going to fix it!" and when my son said that hurts, his response was "What hurts? I'm not even touching you. You need to stop moving and stop talking" Please note, the procedure started at am and he did not finish until 11:30 a.m. Adults have a hard time getting fillings or extractions, imagine a 6 year old who is being yelled at in a stern tone of voice during the entire procedure! At the dentist's first break, I told him perhaps he needed to be more patient, less rude, and that his associate was better at dealing with children, and I would make future appointments with his associate if he continued to treat my child in this manner. His response was "I think that is an excellent idea" while he walked away from me. At no time did he apologize or acknowledge his actions. He is also extremely rude to his staff. The dental assistant was nice and patient, yet the Dr. Derenzo yelled at her several times during the procedure in an insulting and demeaning manner. When we finished my son cried and was so upset partly because he was in pain but mostly because the dentist was yelling at him. It's been more than 24 hours since his procedure, his mouth is still extremely swollen and my son can hardly eat. When his associate completed the first procedure none of this occurred and we are all amazed at how well a 6 year old had done during such a painful procedure. Perhaps it is time from Dr. Derenzo to retire as a pediatric dentist. He does not have the patience to deal with his adult staff yet alone children, imagine how he is treating his patients who are all minors, and from what I have seen are mainly within the ages of 4 - 8 years old, if he disrespects his team in front of patients. I do NOT recommend this dentistry to anyone and if I could post the review with ZERO stars I would have! My review will be in English & Spanish as I note a lot of Hispanic patients come to this practice and the parents allow their children to enter alone without realizing how Dr. Derenzo down talks the children, his patients, and his team. read more
