Very nice - *Dr. Serrano. Explained why chemo treatments need to be done before the surgery in order to shrink cancer & see borders of cancer. Will need CT scan of area when halfway thru a regimen of pre-surgery chemo.

Great experience as a first timer. I barely waited to be helped when I checked in. The staff and Dr. Serrano were all very friendly and helpful. Dr. Serrano explained everything to me in a very clear manner. He was also kind and friendly. Was referred over by my general doctor and can see why. Highly recommended.

I cannot say enough good things about this wonderful surgeon, who performed my Hand Assited Laproscopic Nephrectomy and enabled me to donate a kidney to my husband. I had an excellent outcome from my surgery. I felt well prepared before my surgery, and well taken care of and safe throughout my hospital stay. Dr. Serrano has an excellent bedside manner and patiently answered all my questions and addressed my concerns. My husband and I will be forever grateful to Dr. Serrano, Dr. Morgan and the entire Hartford Hospital Transplant Team of Superheroes :)

Unfortunately, I have being dealing with many Doctors over the years and Dr Serrano is as good as it gets. He staff is equally amazing. I had been dealing with Doctors from Yale New Haven and they just weren't as competent. He takes the time, so you understand what you need to do. Every question received a thoughtful response. He is awesome!!
