From the great vibe in the office, to the high-tech equipment, Gage Endodontics is where you want to go if you need a Endodontist. Dr Castellano treated me. I found her to be knowledgable, professional, empathetic and completely honest about my treatment options. I recommend this practice without hesitation.

I was pleased with my visit. I was lost and I called for directions. They were so nice and told me to take my time. I arrived on time and I was received with smiles The dental assistant and dentist were fabulous. They explained everything as they did the root canal. Later that evening I received a text to check in on how I was doing. I felt special and important. I love the time and energy the whole staff took to make me feel welcome. The endodontist was the best. Patient and understanding. I recommend Gage Endodontics to anyone needing a root canal. They are the best. Thank you all for your kindness and support.

I don’t do well at the dentist’s office, and root canals are the worst. Dr. Castellanos did an excellent job talking me through the process. I actually dosed off during the procedure for a few seconds. Entire office staff was great.

Had a very excellent experience at Gage endontics . Was nervous about having root canal treatment . All the staff were pleasant and welcoming .Dr Castellanos was professional and explained everything , Unfortunately my tooth was unable to be saved. I still felt that Dr Castellanos gave her best effort to help me. I would highly recommend this office .

I had a great experience during my consultation. The doctor was professional, thorough, and took the time to clearly explain everything and answer my questions. The staff was also very kind and welcoming. I left feeling informed and much more at ease.

I had an excellent experience at Gage Endodontics, especially with Dr. Jennifer Castellanos, D.D.S. She is highly intelligent, knowledgeable, and brings a reassuring sense of warmth and lightness to her care. I was being treated for a periradicular radiolucency, and what could have been a painful and uncomfortable procedure turned out to be very manageable. Under Dr. Castellanos’s care, I felt at ease the entire time—the two-hour appointment went by surprisingly quickly. She performed a bicuspid restoration and precisely eliminated the infected area using advanced laser technology. Her skill and attention to detail were evident throughout the procedure. Her assistant Elizabeth was just as wonderful. I truly cannot recommend this dental office enough.
